Как изменить url через js - Исправление ошибок и поиск оптимальных решений проблем

I have the following code that changes the pages from within JavaScript:

var newUrl = [some code to build up URL string];
window.location.replace(newUrl);

But it doesn’t change the top URL, so when someone clicks the back button it doesn’t go back to the previous page.

How can I have JavaScript change the top URL as well so the browser back button works.

Simple assigning to window.location or window.location.href should be fine:

window.location = newUrl;

However, your new URL will cause the browser to load the new page, but it sounds like you’d like to modify the URL without leaving the current page. You have two options for this:

Use the URL hash. For example, you can go from example.com to example.com#foo without loading a new page. You can simply set window.location.hash to make this easy. Then, you should listen to the HTML5 hashchange event, which will be fired when the user presses the back button. This is not supported in older versions of IE, but check out jQuery BBQ, which makes this work in all browsers.
You could use HTML5 History to modify the path without reloading the page. This will allow you to change from example.com/foo to example.com/bar. Using this is easy:

window.history.pushState("example.com/foo");

When the user presses «back», you’ll receive the window’s popstate event, which you can easily listen to (jQuery):

$(window).bind("popstate", function(e) { alert("location changed"); });

Unfortunately, this is only supported in very modern browsers, like Chrome, Safari, and the Firefox 4 beta.

If you just want to update the relative path you can also do

window.location.pathname = '/relative-link'

"http://domain.com" -> "http://domain.com/relative-link"

Hmm, I would use

window.location = 'http://localhost/index.html#?options=go_here';

I’m not exactly sure if that is what you mean.

The best way to redirect the user to another URL is by using window.location.assign (See https://developer.mozilla.org/en-US/docs/Web/API/Location/assign).

Nevertheless, if what you want is to change the URL of the page without redirecting the user, then you may use the window.history.replaceState function (See https://developer.mozilla.org/en-US/docs/Web/API/History/replaceState). A combination of this and window.history.pushState is what Single Page Applications (SPAs) use nowadays to keep track of the user navigating throughout the application so that the back button works as expected

You can take a look at the examples in the documentation links I provided to give you an idea on the usage of these functions

If you want it to work in browsers that don’t support history.pushState and history.popState yet, the «old» way is to set the fragment identifier, which won’t cause a page reload.

The basic idea is to set the window.location.hash property to a value that contains whatever state information you need, then either use the window.onhashchange event, or for older browsers that don’t support onhashchange (IE < 8, Firefox < 3.6), periodically check to see if the hash has changed (using setInterval for example) and update the page. You will also need to check the hash value on page load to set up the initial content.

If you’re using jQuery there’s a hashchange plugin that will use whichever method the browser supports. I’m sure there are plugins for other libraries as well.

One thing to be careful of is colliding with ids on the page, because the browser will scroll to any element with a matching id.

With HTML 5, use the history.pushState function. As an example:

<script type="text/javascript">
var stateObj = { foo: "bar" };
function change_my_url()
{
   history.pushState(stateObj, "page 2", "bar.html");
}
var link = document.getElementById('click');
link.addEventListener('click', change_my_url, false);
</script>

and a href:

<a href="#" id='click'>Click to change url to bar.html</a>

If you want to change the URL without adding an entry to the back button list, use history.replaceState instead.

window.location.href contains the current URL. You can read from it, you can append to it, and you can replace it, which may cause a page reload.

If, as it sounds like, you want to record javascript state in the URL so it can be bookmarked, without reloading the page, append it to the current URL after a # and have a piece of javascript triggered by the onload event parse the current URL to see if it contains saved state.

If you use a ? instead of a #, you will force a reload of the page, but since you will parse the saved state on load this may not actually be a problem; and this will make the forward and back buttons work correctly as well.

answered Sep 25, 2008 at 22:19

I would strongly suspect this is not possible, because it would be an incredible security problem if it were. For example, I could make a page which looked like a bank login page, and make the URL in the address bar look just like the real bank!

Perhaps if you explain why you want to do this, folks might be able to suggest alternative approaches…

[Edit in 2011: Since I wrote this answer in 2008, more info has come to light regarding an HTML5 technique that allows the URL to be modified as long as it is from the same origin]

jQuery has a great plugin for changing browsers’ URL, called jQuery-pusher.

JavaScript pushState and jQuery could be used together, like:

history.pushState(null, null, $(this).attr('href'));

Example:

$('a').click(function (event) {

  // Prevent default click action
  event.preventDefault();     

  // Detect if pushState is available
  if(history.pushState) {
    history.pushState(null, null, $(this).attr('href'));
  }
  return false;
});

Using only JavaScript history.pushState(), which changes the referrer, that gets used in the HTTP header for XMLHttpRequest objects created after you change the state.

Example:

window.history.pushState("object", "Your New Title", "/new-url");

The pushState() method:

pushState() takes three parameters: a state object, a title (which is currently ignored), and (optionally) a URL. Let’s examine each of these three parameters in more detail:

state object — The state object is a JavaScript object which is associated with the new history entry created by pushState(). Whenever the user navigates to the new state, a popstate event is fired, and the state property of the event contains a copy of the history entry’s state object.

The state object can be anything that can be serialized. Because Firefox saves state objects to the user’s disk so they can be restored after the user restarts her browser, we impose a size limit of 640k characters on the serialized representation of a state object. If you pass a state object whose serialized representation is larger than this to pushState(), the method will throw an exception. If you need more space than this, you’re encouraged to use sessionStorage and/or localStorage.
title — Firefox currently ignores this parameter, although it may use it in the future. Passing the empty string here should be safe against future changes to the method. Alternatively, you could pass a short title for the state to which you’re moving.
URL — The new history entry’s URL is given by this parameter. Note that the browser won’t attempt to load this URL after a call to pushState(), but it might attempt to load the URL later, for instance after the user restarts her browser. The new URL does not need to be absolute; if it’s relative, it’s resolved relative to the current URL. The new URL must be of the same origin as the current URL; otherwise, pushState() will throw an exception. This parameter is optional; if it isn’t specified, it’s set to the document’s current URL.

Browser security settings prevent people from modifying the displayed url directly. You could imagine the phishing vulnerabilities that would cause.

Only reliable way to change the url without changing pages is to use an internal link or hash. e.g.: http://site.com/page.html becomes http://site.com/page.html#item1 . This technique is often used in hijax(AJAX + preserve history).

When doing this I’ll often just use links for the actions with the hash as the href, then add click events with jquery that use the requested hash to determine and delegate the action.

I hope that sets you on the right path.

I was wondering if it will posible as long as the parent path in the page is same, only something new is appended to it.

So like let’s say the user is at the page: http://domain.com/site/page.html
Then the browser can let me do location.append = new.html
and the page becomes: http://domain.com/site/page.htmlnew.html and the browser does not change it.

Or just allow the person to change get parameter, so let’s location.get = me=1&page=1.

So original page becomes http://domain.com/site/page.html?me=1&page=1 and it does not refresh.

The problem with # is that the data is not cached (at least I don’t think so) when hash is changed. So it is like each time a new page is being loaded, whereas back- and forward buttons in a non-Ajax page are able to cache data and do not spend time on re-loading the data.

From what I saw, the Yahoo history thing already loads all of the data at once. It does not seem to be doing any Ajax requests. So when a div is used to handle different method overtime, that data is not stored for each history state.

I’ve had success with:

location.hash="myValue";

It just adds #myValue to the current URL. If you need to trigger an event on page Load, you can use the same location.hash to check for the relevant value. Just remember to remove the # from the value returned by location.hash e.g.

var articleId = window.location.hash.replace("#","");

In this quick article, we’ll discuss how to change the URL in JavaScript by redirecting. We’ll go through a couple of different methods that you can use to perform JavaScript redirects.

JavaScript is one of the core technologies of the web. The majority of websites use it, and all modern web browsers support it without the need for plugins. In this series, we’re discussing different tips and tricks that might help you in your day-to-day JavaScript development.

When you’re working with JavaScript, you often need to redirect users to a different page. JavaScript provides different ways of doing that.

Today, we’ll discuss how to perform URL redirections in vanilla JavaScript and with the jQuery library.

How to Change the URL in Vanilla JavaScript

In this section, we’ll go through the different built-in methods provided by JavaScript to implement URL redirection. In fact, JavaScript provides the location object, a part of the window object, which allows you to perform different URL-related operations.

The `location.href` Method

The location.href method is one of the most popular ways to perform JavaScript redirects. If you try to get the value of location.href, it returns the value of the current URL. Similarly, you can also use it to set a new URL, and users will then be redirected to that URL.

Let’s go through the following example.

console.log(location.href);
// prints the current URL

location.href = 'https://code.tutsplus.com';
// redirects the user to https://code.tutsplus.com

As you can see, it’s fairly easy to redirect users with the location.href method. Since the location object is part of the window object, the above snippet can also be written as:

1	window.location.href = 'https://code.tutsplus.com';

So in this way, you can use the location.href method to change the URL and redirect users to a different webpage.

The `location.assign` Method

The location.assign method works very similarly to the location.href method and allows you to redirect users to a different web page.

Let’s quickly see how it works with the following example.

1	location.assign('https://code.tutsplus.com');

As you can see, it’s pretty straightforward. You just need to pass the URL in the first argument of the assign method, and it will redirect users to that URL. It’s important to note that the assign method maintains the state of the History object. We’ll discuss this in detail in the next section.

The `location.replace` Method

You can also use the location.replace method to perform JavaScript redirects. The location.replace method allows you to replace the current URL with a different URL to perform redirection.

Let’s see how it works with the following example.

1	location.replace('https://code.tutsplus.com');

Although the location.replace method looks very similar to the location.href and location.assign methods of redirecting users to a different URL, there’s an important difference between them. When you use the location.replace method, the current page won’t be saved in the session, and it’s actually removed from the JavaScript History object. So users won’t be able to use the back button to navigate to it.

Let’s try to understand it with the following example.

// let’s assume that a user is browsing https://code.tutsplus.com

// a user is redirected to a different page with the location.href method
location.href = 'https://design.tutsplus.com';

// a user is redirected to a different page with the location.replace method
location.replace('https://business.tutsplus.com');

In the above example, we’ve assumed that a user is browsing the https://code.tutsplus.com webpage. Next, we have used the location.href method to redirect the user to the https://design.tutsplus.com webpage. Finally, we’ve used the location.replace method to redirect the user to the https://business.tutsplus.com webpage. Now, if the user clicks on the back button, it would go back to https://code.tutsplus.com instead of https://design.tutsplus.com, since we’ve used the location.replace method, and it has actually replaced the current URL with https://business.tutsplus.com in the History object.

So you should understand the difference between location.replace and other methods before you use them. You can’t use them interchangeably since the location.replace method alters the state of the JavaScript History object. And thus, if you want to preserve the state of the History object, you should use other methods of redirecting users.

How to Perform URL Redirections With jQuery

Although vanilla JavaScript offers enough options when it comes to URL redirection, if you’re still wondering how to do it with the jQuery library, we’ll quickly go through it in this section.

In jQuery, you can use the attr method to perform redirection, as shown in the following snippet.

1	$(location).attr('href', 'https://design.tutsplus.com');

As you can see, it’s fairly easy to redirect users with jQuery!

So that’s it for the different ways of performing JavaScript redirects. And with that, we’ve reached the end of this quick article as well.

Conclusion

Today, we discussed how you can implement JavaScript redirects. We discussed different methods that you can use to perform JavaScript redirects, along with some examples.

Свойства window.location

window.location

.origin
Базовый URL (Протокол + имя хоста + номер порта)

.protocol
Протокол (http: или https)

.host
Доменное имя + порт

.hostname
Доменное имя

.port
Имя порта

.pathname
Строка пути (относительно хоста)

.search
Часть строки, которая следует после? (включая ?)

.hash
Часть строки, которая следует после # (якорь или идентификатор фрагмента)

.href
Полный URL

Разница между host и hostname

В моем примере выше ты заметишь, что

host

hostname

возвращают одно и то же значение. Так в чем же разница. Ну, это связано с номером порта. Давай взглянем.

URL без порта

https://voiti-v-it.com

window.location.host; // ‘voiti-v-it.com’
window.location.hostname; // ‘voiti-v-it.com’
window.location.port; // »

URL с портом

http://voiti-v-it.com:8080

window.location.host; // ‘voiti-v-it.com:8080’
window.location.hostname; // ‘voiti-v-it.com’
window.location.port; // ‘8080’

Таким образом,

host

будет содержать номер порта, тогда как

hostname

будет возвращать только имя хоста.

Как изменить свойства URL

Ты можешь не только вызвать свойства объекта

location

чтобы получить информацию об URL. Ты можешь использовать его для установки новых свойств и изменения URL. Посмотрим, что я имею в виду.

http://voiti-v-it.com:8080

window.location.host; // ‘voiti-v-it.com:8080’
window.location.hostname; // ‘voiti-v-it.com’
window.location.port; // ‘8080’

Вот полный список свойств, которые ты можешь изменить:

http://voiti-v-it.com:8080
window.location.host; // ‘voiti-v-it.com:8080’
window.location.hostname; // ‘voiti-v-it.com’
window.location.port; // ‘8080’

Единственное свойство, которое ты не можешь установить, это

window.location.origin

Это свойство доступно только для чтения.

Объект Location

window.location

возвращает объект

Location

который дает тебе информацию о текущем местоположении страницы. Ты также можешь получить доступ к объекту Location несколькими способами.

http://voiti-v-it.com:8080

window.location.host; // ‘voiti-v-it.com:8080’
window.location.hostname; // ‘voiti-v-it.com’
window.location.port; // ‘8080’

Объект доступен таким образом, потому что является глобальной переменной в браузере.

window.location vs location

Каждый из 4х свойств выше указывают на один и тот же объект

Location

Я лично предпочитаю

window.location

и на самом деле не буду использовать

location

Главным образом потому, что

location

читается больше как общий термин, и кто-то может случайно назвать свою переменную, которая переопределяет глобальную переменную. Взять, к примеру:

// https://www.samanthaming.com

location.protocol; // ‘https’

function localFile() {
const location = ‘/sam’;
return location.protocol;
// ❌ undefined
// локальная «location» преопределяет глобальную переменную
}

Я думаю, что большинство разработчиков знают, что

window

является глобальной переменной. Так что у тебя меньше шансов вызвать путаницу. Поэтому я рекомендую использовать

window.location

вместо

location

Вот мой личный порядок предпочтений:

// ✅
1. window.location // 🏆
2. document.location
// ❌
3. window.document.location // почему бы просто не использовать #1 or #2 😅
4. location // чувствуется слишком двусмысленно 😵

Конечно, это всего лишь мои предпочтения. Ты эксперт в своей кодовой базе, лучшего способа нет, лучший всегда тот, который подходит тебе и твоей команде.🤓

Методы window.location

window.location

.assign()
Навигация происходит по указанному URL

.replace()
Навигация происходит по указанному URL & и текущая страница удаляется из истории

.reload()
Перезагружает текущую страницу

.toString()
Returns the URL

window.location.toString

Вот определение из MDN

Этот метод возвращает USVString URL. Версия только для чтения

Location.href

Другими словами, ты можешь использовать его для получения значения

href

из

// https://voiti-v-it.com

window.location.href; // https://voiti-v-it.com

window.location.toString(); // https://voiti-v-it.com

Что касается использования, я не смог найти много информации о том, что лучше; но если ты это сделаешь, пожалуйста, поделись в комментах 😊. Я нашел тест производительности на разницу.

Один момент, который я хочу отметить в отношении этих тестов скорости, заключается в том, что они зависят от браузера. Различные браузеры и версии будут иметь разные результаты. Я использую Chrome, поэтому href вышел быстрее остальных. Так что я буду этим пользоваться. Также я думаю, что он читается более явно, чем

toString()

Совершенно очевидно, что

href

предоставит URL, тогда как

toString

выглядит как нечто, преобразуемое в строку.😅

assign vs replace

Оба эти метода помогут тебе перейти по другому URL. Разница в том, что

assign

сохранит твою текущую страницу в истории, поэтому твой пользователь может использовать кнопку «назад» для перехода к ней. Принимая во внимание метод

replace

он не сохраняет его истории. Это немного смущает, да? Меня тоже. Давай пройдемся по примерам.

Assign

1. Открыть новую вкладку
2. Перейти https://voiti-v-it.com (текущая страница)
3. Загрузить нвоую страницу 👉 `window.location.assign(‘https://www.w3schools.com’)`
4. Нажать «назад»
5. Вернемся на 👉 https://voiti-v-it.com

Replace

Текущая страница

Мне просто нужно подчеркнуть «текущая страница» в определении. Это страница прямо перед

assign

или

replace

1. Открыть новую вкладку
2. Перейти www.developer.mozilla.org
3. Перейти https://voiti-v-it.com 👈 это будет текущая страница
4. window.location.assign(‘https://www.w3schools.com’); // Перейдет к #3
4. window.location.replace(‘https://www.w3schools.com’); // Перейдет к #2

Как сделать редирект страницы

Теперь ты знаешь, что мы можем изменить свойства

window.location

присвоив значение с помощью

Точно так же существуют методы, к которым мы можем получить доступ для выполнения некоторых действий. Итак, что касается «как перенаправить/редиректить на другую страницу», то есть 3 способа.

// Установить свойство href
window.location.href = ‘https://voiti-v-it.com’;
// Использование Assign
window.location.assign(‘https://voiti-v-it.com’);
// Использование Replace
window.location.replace(‘https://voiti-v-it.com’);

replace vs assign vs href

Все три перенаправляют, разница связана с историей браузера.

href

assign

здесь одинаковы. Они сохранят твою текущую страницу в истории, а

replace

— нет. Так что, если ты предпочитаешь опыт создания, когда навигация не может вернуться на исходную страницу, используй

replace

Таким образом, вопрос сейчас:

href

assign

Я считаю, что это личные предпочтения. Мне больше нравится

assign

потому что это метод, поэтому мне кажется, что я выполняю какое-то действие. Также есть дополнительный бонус в том, что его проще тестировать. Я писал много Jest-тестов, поэтому, используя метод можно просто замокать данные.

window.location.assign = jest.fn();
myUrlUpdateFunction();
expect(window.location.assign).toBeCalledWith(‘http://my.url’);

Но для тех, которые болеют за

href

для редиректа страницы. Я нашел тест производительности и он работает в моей версии Chrome быстрее. Опять же, тесты производительности варьируются в зависимости от браузера и разных версий, сейчас это может быть быстрее, но, возможно, в будущих браузерах всё может измениться.

Как это все появилось 👍

Ладно, я готов с вами поделиться как появилась эта шпаргалка. Я гуглил, как редиректить на другую страницу, и столкнулся с объектом

window.location

Иногда я чувствую, что разработчик является журналистом или детективом — для того, чтобы собрать всю доступную информацию, приходится много копаться и прочесывать разные источники. Честно говоря, я был ошеломлен материалами, они все были “о разном”, а я просто хотел всё из одного источника. Я не мог найти много полной информации, поэтому я подумал, а расскажу-ка я об этом в шпаргалке!

Источник

The Window.location read-only property returns a
Location object with information about the current location of the
document.

Though Window.location is a read-only Location
object, you can also assign a string to it. This means that you can
work with location as if it were a string in most cases:
location = 'http://www.example.com' is a synonym of
location.href = 'http://www.example.com'.

See Location for all available properties.

Value

Examples

Basic Example

alert(location); // alerts "https://developer.mozilla.org/en-US/docs/Web/API/Window/location"

Example 1: Navigate to a new page

Whenever a new value is assigned to the location object, a document will be loaded
using the URL as if location.assign() had been called with the modified
URL.

Note that navigation-related sandbox flags may result in an exception being thrown and the navigation failing.

location.assign("http://www.mozilla.org"); // or
location = "http://www.mozilla.org";

Example 2: Reloading the current page

Example 3

Consider the following example, which will reload the page by using the replace() method to
insert the value of location.pathname into the hash:

function reloadPageWithHash() {
  location.replace(`http://example.com/#${location.pathname}`);
}

Example 4: Display the properties of the current URL in an alert dialog

function showLoc() {
  const logLines = ["Property (Typeof): Value", `location (${typeof location}): ${location}`];
  for (const prop in location) {
    logLines.push(`${prop} (${typeof location[prop]}): ${location[prop] || "n/a"}`);
  }
  alert(logLines.join("n"));
}

// in html: <button onclick="showLoc();">Show location properties</button>

Example 5: Send a string of data to the server by modifying the `search` property

function sendData(data) {
  location.search = data;
}

// in html: <button onclick="sendData('Some data');">Send data</button>

The current URL with «?Some%20data» appended is sent to the server (if no action is
taken by the server, the current document is reloaded with the modified search string).

Example 6: Using bookmarks without changing the `hash` property

<!DOCTYPE html>
<html lang="en-US">
  <head>
    <meta charset="UTF-8" />
    <title>MDN Example</title>
    <script>
      function showNode(node) {
        document.documentElement.scrollTop = node.offsetTop;
        document.documentElement.scrollLeft = node.offsetLeft;
      }

      function showBookmark(bookmark, useHash) {
        if (arguments.length === 1 || useHash) {
          location.hash = bookmark;
          return;
        }
        const bookmarkElement = document.querySelector(bookmark);
        if (bookmarkElement) {
          showNode(bookmarkElement);
        }
      }
    </script>
    <style>
      span.intLink {
        cursor: pointer;
        color: #0000ff;
        text-decoration: underline;
      }
    </style>
  </head>

BCD tables only load in the browser

Redirecting to a URL is one of the most common activities performed by JavaScript. As such, JavaScript offers multiple different ways to support redirects from the code level. In this article we’ll look at how to change a URL using JavaScript, reviewing each of the potential methods in turn.

1. Using the Location Interface

The first approach uses the Location interface. Take the following sample JavaScript code and HTML markup:

JavaScript

function goGoogle() {
  window.location = 'http://google.com'
}

HTML

<button onclick="goGoogle()">Google it</button>

When the button defined in the HTML above is clicked, it invokes function goGoogle(). This function modifies the window object’s location property, which redirects the user to the main Google Search page.

Syntax

The syntax for redirecting via window.location is as follows:

window.location = URL

This code is flexible, and will work perfectly fine even if you omit the keyword window. Additionally, you can set the href property of location, which will also perform the desired redirect.

Location methods

The location property has several useful methods associated with it. Below are three of the most commonly-used methods:

location.assign(URL): This method redirects the user to the specified URL. The user’s browser history will be updated with the new URL visited.

location.reload(URL): This method refreshes the current page.

location.replace(URL): This method, similar to assign, redirects the user to the specified URL. The critical difference is that the replace() method does not update the user’s browser history (more detail below), preventing the user from navigating back to the current page. This can be helpful when you need to hide a page from being exposed to the user.

Note: In all cases above, the URL parameter is a String.

2. Using the History API

The second approach to changing the URL is using the History API. The browser’s session history is accessible via the history object in JavaScript. This object has several methods, three of which we explore below:

back() – this method navigates the user back one entry in their browser history, as though the user pressed the “back” button in their browser.

forward() – this method navigates the user forward one entry in their browser history, as though the user pressed the “forward” button in their browser.

go(target) – this takes a user directly to an entry. This method takes a parameter, target, which controls the redirection. This can be a URL string, in which case the user is redirected to the URL specified, or a number. If a number is provided, the user is moved forwards (in the case of positive numbers) or backwards (in the case of negative numbers) in their browser history. Passing “0” to this function refreshes the page.

The following example code shows how to use the go() method to navigate the user’s browser history:

JavaScript

function go2pagesBack() {
  history.go(-2)
}

Invoking the go2pagesBack() function is similar to pressing the browser’s back button twice, due to our choice to send “-2” as a parameter to history.go().

Note: If the user does not have enough pages in their history to accommodate the request, the go() method will redirect as far as it can. For example, if you have only one page in your history, history.go(-2) will only go back one page.

3. Create an HTML hyperlink

The final method of redirecting the user is simply creating an HTML hyperlink that controls the navigation. Take the following example HTML markup:

HTML

<a href="http://codota.com/">Codota</a>

● The <a> element defines a hyperlink, with the text between the tags being presented to the user.

● The href attribute sets the link’s destination, redirecting the user to the provided URL.

This method uses HTML only, but can be easily modified as needed using JavaScript.

Note: It is possible to change the href attribute, for instance, by using the setAttribute() method.

Как заменить ссылку в «href» с помощью javascript? Проведем несколько примеров. заменим ссылку в href, потом заменим текст, и последним заменим и текст и ссылку по одному нажатию!

Как заменить адрес ссылки «href» javascript

Огромное количество способов «заменить адрес ссылки javascript».

Рассмотрим пример изменения адресы в атрибуте href через javascript.

Нам понадобится :

Возьмем тег div.

Поместим вовнутрь onclick с функцией.

<button onclick=»changeURL()»>Изменить адрес</button>

Далее нам понадобится ссылка, где у нас есть атрибут «href» и обратиться к тегу через id .

<a href=»https://ya.ru/» id=»yandex»>Yandex</a>

далее нам нужно написать ту самую функцию — она будет очень простая :

Стенд для визуализации процесса замены ссылки в реальном времени.

У нас будет вот такая ссылка :

<a href=»https://ya.ru/» id=»yandex»>Yandex</a>

Чтобы увидеть замену ссылки в реальном времени — нажмите на кнопку «Изменить адрес» и смотрите на адрес выше данной строки.

Пример ссылки с измененным адресом ссылки

И теперь та же самая ссылка уже в коде:

Как заменить текст в ссылке

Возьмем этот же пример, только чуть его модернизируем! Напоминаю, что вы можете взять любой способ onclick и обратиться к тегу

Изменим внутри тега название функции :

<button onclick=»changeURL_1()»>Изменить текст</button>

В теге ссылки изменим id — должен быть уникальным.

<a href=»https://ya.ru/» id=»yandex1″>Yandex</a>

И немного javascript :

Тестируем замену текста в ссылке :

Yandex

Замена текста в ссылке и адреса в «href» javascript

И третьим пунктом следим оба скрипта в один, чтобы мы смогли по одном нажатию заменить и текст и адрес ссылки.

Кнопка :

<button onclick=»changeURL_2()»>Изменить адрес и текст</button>

Ссылка :

<a href=»https://ya.ru/» id=»yandex2″>Yandex</a>

javascript :

Результат:

Yandex

javascript заменить текст во всех ссылках

Если мы заменяли текст в определенной ссылке, то почему бы не заменить текст во всех ссылках!?

Сделаем кнопку, чтобы было видно добавление текста ссылкам :

<button onclick=»send_atr();»>button</button>

Добавим атрибут style с цветом красный — red

function send_text()
{
var links = document.querySelectorAll(«a»);
links.forEach(link => {
link.innerHTML = «Новое содержимое во всех ссылках»;
})
}
}

Добавим вторую , чтобы изменить содержание текст а ссылки ещё раз…

И две ссылки для наглядности.

Чтобы увидеть изменение текста ссылки, две подопытные ссылки

Подопытные ссылки :
текст

текст

Кнопки для добавления всем ссылкам атрибута.

javascript заменить адрес во всех ссылках.

Следующим пунктом заменим все адреса ссылок на всей странице!

Алгоритм аналогичный!

HTML

Чтобы вы могли сделать замену ссылке нажав по кнопке, нам потребуется такая кнопка button + onclick с функцией:

<button onclick=»send_newlink();»>Добавим новый адрес во все ссылки</button>

javascript

Опять немного javascript…

function send_newlink()
{
var links = document.querySelectorAll(«a»);
links.forEach(link => {
link.href=»https://google.com»;
})
}

Результат замены, чтобы протестировать замену ссылок на всей странице нажмите по кнопке, а потом по любой ссылке… либо откройте исследовать элемент и сможете наблюдать в процессе, за любой ссылкой..
