我如何重定向到另一个网页?

How can I redirect the user from one page to another using jQuery or pure JavaScript?


One does not simply redirect using jQuery

jQuery is not necessary, and window.location.replace(...) will best simulate an HTTP redirect.

window.location.replace(...) is better than using window.location.href, because replace() does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.

If you want to simulate someone clicking on a link, use location.href

If you want to simulate an HTTP redirect, use location.replace

For example:

// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");

// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";

WARNING: This answer has merely been provided as a possible solution; it is obviously not the best solution, as it requires jQuery. Instead, prefer the pure JavaScript solution.

$(location).attr('href', 'http://stackoverflow.com')

Standard "vanilla" JavaScript way to redirect a page:

window.location.href = 'newPage.html';


If you are here because you are losing HTTP_REFERER when redirecting, keep reading:


The following section is for those using HTTP_REFERER as one of many secure measures (although it isn't a great protective measure). If you're using Internet Explorer 8 or lower, these variables get lost when using any form of JavaScript page redirection (location.href, etc.).

Below we are going to implement an alternative for IE8 & lower so that we don't lose HTTP_REFERER. Otherwise you can almost always simply use window.location.href.

Testing against HTTP_REFERER (URL pasting, session, etc.) can be helpful in telling whether a request is legitimate. (Note: there are also ways to work-around / spoof these referrers, as noted by droop's link in the comments)


Simple cross-browser testing solution (fallback to window.location.href for Internet Explorer 9+ and all other browsers)

Usage: redirect('anotherpage.aspx');

function redirect (url) {
    var ua        = navigator.userAgent.toLowerCase(),
        isIE      = ua.indexOf('msie') !== -1,
        version   = parseInt(ua.substr(4, 2), 10);

    // Internet Explorer 8 and lower
    if (isIE && version < 9) {
        var link = document.createElement('a');
        link.href = url;
        document.body.appendChild(link);
        link.click();
    }

    // All other browsers can use the standard window.location.href (they don't lose HTTP_REFERER like Internet Explorer 8 & lower does)
    else { 
        window.location.href = url; 
    }
}

Use:

// window.location
window.location.replace('http://www.example.com')
window.location.assign('http://www.example.com')
window.location.href = 'http://www.example.com'
document.location.href = '/path'

// window.history
window.history.back()
window.history.go(-1)

// window.navigate; ONLY for old versions of Internet Explorer
window.navigate('top.jsp')


// Probably no bueno
self.location = 'http://www.example.com';
top.location = 'http://www.example.com';

// jQuery
$(location).attr('href','http://www.example.com')
$(window).attr('location','http://www.example.com')
$(location).prop('href', 'http://www.example.com')

2018年02月24日56分15秒

This works for every browser:

window.location.href = 'your_url';

It would help if you were a little more descriptive in what you are trying to do. If you are trying to generate paged data, there are some options in how you do this. You can generate separate links for each page that you want to be able to get directly to.

<a href='/path-to-page?page=1' class='pager-link'>1</a>
<a href='/path-to-page?page=2' class='pager-link'>2</a>
<span class='pager-link current-page'>3</a>
...

Note that the current page in the example is handled differently in the code and with CSS.

If you want the paged data to be changed via AJAX, this is where jQuery would come in. What you would do is add a click handler to each of the anchor tags corresponding to a different page. This click handler would invoke some jQuery code that goes and fetches the next page via AJAX and updates the table with the new data. The example below assumes that you have a web service that returns the new page data.

$(document).ready( function() {
    $('a.pager-link').click( function() {
        var page = $(this).attr('href').split(/\?/)[1];
        $.ajax({
            type: 'POST',
            url: '/path-to-service',
            data: page,
            success: function(content) {
               $('#myTable').html(content);  // replace
            }
        });
        return false; // to stop link
    });
});

I also think that location.replace(URL) is the best way, but if you want to notify the search engines about your redirection (they don't analyze JavaScript code to see the redirection) you should add the rel="canonical" meta tag to your website.

Adding a noscript section with a HTML refresh meta tag in it, is also a good solution. I suggest you to use this JavaScript redirection tool to create redirections. It also has Internet Explorer support to pass the HTTP referrer.

Sample code without delay looks like this:

<!-- Place this snippet right after opening the head tag to make it work properly -->

<!-- This code is licensed under GNU GPL v3 -->
<!-- You are allowed to freely copy, distribute and use this code, but removing author credit is strictly prohibited -->
<!-- Generated by http://insider.zone/tools/client-side-url-redirect-generator/ -->

<!-- REDIRECTING STARTS -->
<link rel="canonical" href="https://yourdomain.com/"/>
<noscript>
    <meta http-equiv="refresh" content="0;URL=https://yourdomain.com/">
</noscript>
<!--[if lt IE 9]><script type="text/javascript">var IE_fix=true;</script><![endif]-->
<script type="text/javascript">
    var url = "https://yourdomain.com/";
    if(typeof IE_fix != "undefined") // IE8 and lower fix to pass the http referer
    {
        document.write("redirecting..."); // Don't remove this line or appendChild() will fail because it is called before document.onload to make the redirect as fast as possible. Nobody will see this text, it is only a tech fix.
        var referLink = document.createElement("a");
        referLink.href = url;
        document.body.appendChild(referLink);
        referLink.click();
    }
    else { window.location.replace(url); } // All other browsers
</script>
<!-- Credit goes to http://insider.zone/ -->
<!-- REDIRECTING ENDS -->

But if someone wants to redirect back to home page then he may use the following snippet.

window.location = window.location.host

It would be helpful if you have three different environments as development, staging, and production.

You can explore this window or window.location object by just putting these words in Chrome Console or Firebug's Console.

2018年02月24日56分15秒

JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows..

var currentLocation = window.location;

Basic Structure of a URL

<protocol>//<hostname>:<port>/<pathname><search><hash>

enter image description here

  1. Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))

  2. hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.com. A server provides services using the name of the host.

  3. port -- A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.

  4. pathname -- The path gives info about the specific resource within the host that the Web client wants to access. For example, stackoverflow.com/index.html.

  5. query -- A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).

  6. hash -- The anchor portion of a URL, includes the hash sign (#).

With these Location object properties you can access all of these URL components

  1. hash -Sets or returns the anchor portion of a URL.
  2. host -Sets or returns the hostname and port of a URL.
  3. hostname -Sets or returns the hostname of a URL.
  4. href -Sets or returns the entire URL.
  5. pathname -Sets or returns the path name of a URL.
  6. port -Sets or returns the port number the server uses for a URL.
  7. protocol -Sets or returns the protocol of a URL.
  8. search -Sets or returns the query portion of a URL

Now If you want to change a page or redirect the user to some other page you can use the href property of the Location object like this

You can use the href property of the Location object.

window.location.href = "http://www.stackoverflow.com";

Location Object also have these three methods

  1. assign() -- Loads a new document.
  2. reload() -- Reloads the current document.
  3. replace() -- Replaces the current document with a new one

You can use assign() and replace methods also to redirect to other pages like these

location.assign("http://www.stackoverflow.com");

location.replace("http://www.stackoverflow.com");

How assign() and replace() differs -- The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.

You can change the location object href property using jQuery also like this

$(location).attr('href',url);

And hence you can redirect the user to some other url.

Should just be able to set using window.location.

Example:

window.location = "https://stackoverflow.com/";

Here is a past post on the subject:

How do I redirect to another webpage?

2018年02月24日56分15秒

Before I start, jQuery is a JavaScript library used for DOM manipulation. So you should not be using jQuery for a page redirect.

A quote from Jquery.com:

While jQuery might run without major issues in older browser versions, we do not actively test jQuery in them and generally do not fix bugs that may appear in them.

It was found here: https://jquery.com/browser-support/

So jQuery is not an end-all and be-all solution for backwards compatibility.

The following solution using raw JavaScript works in all browsers and have been standard for a long time so you don't need any libraries for cross browser support.

This page will redirect to Google after 3000 milliseconds

<!DOCTYPE html>
<html>
    <head>
        <title>example</title>
    </head>
    <body>
        <p>You will be redirected to google shortly.</p>
        <script>
            setTimeout(function(){
                window.location.href="http://www.google.com"; // The URL that will be redirected too.
            }, 3000); // The bigger the number the longer the delay.
        </script>
    </body>
</html>

Different options are as follows:

window.location.href="url"; // Simulates normal navigation to a new page
window.location.replace("url"); // Removes current URL from history and replaces it with a new URL
window.location.assign("url"); // Adds new URL to the history stack and redirects to the new URL

window.history.back(); // Simulates a back button click
window.history.go(-1); // Simulates a back button click
window.history.back(-1); // Simulates a back button click
window.navigate("page.html"); // Same as window.location="url"

When using replace, the back button will not go back to the redirect page, as if it was never in the history. If you want the user to be able to go back to the redirect page then use window.location.href or window.location.assign. If you do use an option that lets the user go back to the redirect page, remember that when you enter the redirect page it will redirect you back. So put that into consideration when picking an option for your redirect. Under conditions where the page is only redirecting when an action is done by the user then having the page in the back button history will be okay. But if the page auto redirects then you should use replace so that the user can use the back button without getting forced back to the page the redirect sends.

You can also use meta data to run a page redirect as followed.

META Refresh

<meta http-equiv="refresh" content="0;url=http://evil.com/" />

META Location

<meta http-equiv="location" content="URL=http://evil.com" />

BASE Hijacking

<base href="http://evil.com/" />

Many more methods to redirect your unsuspecting client to a page they may not wish to go can be found on this page (not one of them is reliant on jQuery):

https://code.google.com/p/html5security/wiki/RedirectionMethods

I would also like to point out, people don't like to be randomly redirected. Only redirect people when absolutely needed. If you start redirecting people randomly they will never go to your site again.

The next part is hypothetical:

You also may get reported as a malicious site. If that happens then when people click on a link to your site the users browser may warn them that your site is malicious. What may also happen is search engines may start dropping your rating if people are reporting a bad experience on your site.

Please review Google Webmaster Guidelines about redirects: https://support.google.com/webmasters/answer/2721217?hl=en&ref_topic=6001971

Here is a fun little page that kicks you out of the page.

<!DOCTYPE html>
<html>
    <head>
        <title>Go Away</title>
    </head>
    <body>
        <h1>Go Away</h1>
        <script>
            setTimeout(function(){
                window.history.back();
            }, 3000);
        </script>
    </body>
</html>

If you combine the two page examples together you would have an infant loop of rerouting that will guarantee that your user will never want to use your site ever again.

2018年02月24日56分15秒

var url = 'asdf.html';
window.location.href = url;

2018年02月24日56分15秒

You can do that without jQuery as:

window.location = "http://yourdomain.com";

And if you want only jQuery then you can do it like:

$jq(window).attr("location","http://yourdomain.com");

2018年02月24日56分15秒

This works with jQuery:

$(window).attr("location", "http://google.fr");

# HTML Page Redirect Using jQuery/JavaScript

Try this example code:

function YourJavaScriptFunction()
{
    var i = $('#login').val();
    if (i == 'login')
        window.location = "login.php";
    else
        window.location = "Logout.php";
}

If you want to give a complete URL as window.location = "www.google.co.in";.

Basically jQuery is a JavaScript library and for doing some of the things like redirection, you can use pure JavaScript, so in that case you have 3 options using vanilla JavaScript:

1) Using location replace, this will replace the current history of the page, means that it is not possible to use the back button to go back to the original page.

window.location.replace("http://stackoverflow.com");

2) Using location assign, this will keep the history for you and with using back button, you can go back to the original page:

window.location.assign("http://stackoverflow.com");

3) I recommend using one of those previous ways, but this could be the third option using pure JavaScript:

window.location.href="http://stackoverflow.com";

You can also write a function in jQuery to handle it, but not recommended as it's only one line pure JavaScript function, also you can use all of above functions without window if you are already in the window scope, for example window.location.replace("http://stackoverflow.com"); could be location.replace("http://stackoverflow.com");

Also I show them all on the image below:

location.replace

2018年02月24日56分15秒

So, the question is how to make a redirect page, and not how to redirect to a website?

You only need to use JavaScript for this. Here is some tiny code that will create a dynamic redirect page.

<script>
    var url = window.location.search.split('url=')[1]; // Get the URL after ?url=
    if( url ) window.location.replace(url);
</script>

So say you just put this snippet into a redirect/index.html file on your website you can use it like so.

http://www.mywebsite.com/redirect?url=http://stackoverflow.com

And if you go to that link it will automatically redirect you to stackoverflow.com.

Link to Documentation

And that's how you make a Simple redirect page with JavaScript

Edit:

There is also one thing to note. I have added window.location.replace in my code because I think it suits a redirect page, but, you must know that when using window.location.replace and you get redirected, when you press the back button in your browser it will not got back to the redirect page, and it will go back to the page before it, take a look at this little demo thing.

Example:

The process: store home => redirect page to google => google

When at google: google => back button in browser => store home

So, if this suits your needs then everything should be fine. If you want to include the redirect page in the browser history replace this

if( url ) window.location.replace(url);

with

if( url ) window.location.href = url;

2018年02月24日56分15秒

On your click function, just add:

window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
    window.location.href = "http://www.google.com";
});

2018年02月24日56分15秒

Try this:

location.assign("http://www.google.com");

Code snippet of example.

2018年02月24日56分15秒

You need to put this line in your code:

$(location).attr("href","http://stackoverflow.com");

If you don't have jQuery, go JavaScript with:

window.location.replace("http://stackoverflow.com");

2018年02月24日56分15秒

jQuery is not needed. You can do this:

window.open("URL","_self","","")

It is that easy!

The best way to initiate an HTTP request is with document.loacation.href.replace('URL').

2018年02月24日56分15秒

First write properly. You want to navigate within an application for another link from your application for another link. Here is the code:

window.location.href = "http://www.google.com";

And if you want to navigate pages within your application then I also have code, if you want.

2018年02月24日56分15秒

You can redirect in jQuery like this:

$(location).attr('href', 'http://yourPage.com/');

2018年02月24日56分15秒

To just redirect to a page:

  window.location.href = "/destination.html";

Or if you need a delay:

setTimeout(function () {
  window.location.href = "/destination.html";
}, 2000);   // Time in milliseconds

jQuery allows you to select elements from a web page with ease. You can find anything you want in a page and then use jQuery to add special effects, react to user actions, or show and hide content inside or outside the element you have selected. All these tasks start with knowing how to select an element.

function redirect () {
    $('selection').animate({
        marginLeft: 100px; //Put some CSS animation here
    }, 500, function () {
      // OK, finished jQuery staff, let's go redirect
      window.location.href = "/destination.html";
})

Imagine someone wrote a script/plugin that is 10000 lines of code?! Well, with jQuery you can connect to this code with just a line or two.

ECMAScript 6 + jQuery, 85 bytes

$({jQueryCode:(url)=>location.replace(url)}).attr("jQueryCode")("http://example.com")

Please don't kill me, this is a joke. It's a joke. This is a joke.

This did "provide an answer to the question", in the sense that it asked for a solution "using jQuery" which in this case entails forcing it into the equation somehow.

Ferrybig apparently needs the joke explained (still joking, I'm sure there are limited options on the review form), so without further ado:

Other answers are using jQuery's attr() on the location or window objects unnecessarily.

This answer also abuses it, but in a more ridiculous way. Instead of using it to set the location, this uses attr() to retrieve a function that sets the location.

The function is named jQueryCode even though there's nothing jQuery about it, and calling a function somethingCode is just horrible, especially when the something is not even a language.

The "85 bytes" is a reference to Code Golf. Golfing is obviously not something you should do outside of code golf, and furthermore this answer is clearly not actually golfed.

Basically, cringe.

2018年02月24日56分15秒

In JavaScript and jQuery we can use the following code to redirect the one page to another page:

window.location.href="http://google.com";
window.location.replace("page1.html");

2018年02月24日56分15秒

Javascript:

window.location.href='www.your_url.com';
window.top.location.href='www.your_url.com';
window.location.replace('www.your_url.com');

Jquery:

var url='www.your_url.com';
$(location).attr('href',url);
$(location).prop('href',url);//instead of location you can use window

2018年02月24日56分15秒

Here is a time-delay redirection. You can set the delay time to whatever you want:

<!doctype html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <title>Your Document Title</title>
    <script type="text/javascript">
        function delayer(delay) {
            onLoad = setTimeout('window.location.href = "http://www.google.com/"', delay);
        }
    </script>
</head>

<body>
    <script>
        delayer(8000)
    </script>
    <div>You will be redirected in 8 seconds!</div>
</body>

</html>

2018年02月24日56分15秒

I just had to update this ridiculousness with yet another newer jQuery method:

var url = 'http://www.fiftywaystoleaveyourlocation.com';
$(location).prop('href', url);

2018年02月24日56分15秒

There are three main ways to do this,

window.location.href='blaah.com';
window.location.assign('blaah.com');

and...

window.location.replace('blaah.com');

The last one is best, for a traditional redirect, because it will not save the page you went to before being redirected in your search history. However, if you just want to open a tab with JavaScript, you can use any of the above.1

EDIT: The window prefix is optional.
