从URL（如php的$ _GET）获取jQuery / Ajax的数据？

问题描述：

What I'm wanting to do is take a URL like myurl.com/page.php?data1=x&data2=y&data3=z and get each piece of data and use it in a jQuery function. Is there any built in way to do that?

To clarify, when I navigate to (say, pasting the url into the address bar, or going to it via a bookmark) I want jQuery to do something with that data.

As a bonus, if it also includes something to check if the data is set to something, that would be great.

我想要做的是使用像myurl.com/page.php?data1=x&这样的网址。 data2 = y＆amp; data3 = z并获取每个数据并在jQuery函数中使用它。有没有内置的方法呢？ p>

澄清一下，当我导航到（比如将网址粘贴到地址栏中，或通过书签转到它）时，我想要jQuery 用这些数据做点什么。 p>

作为奖励，如果它还包括检查数据是否设置为某物的东西，那就太棒了。 p> DIV>

A quick way to do it would be if your javascript code is embedded in a php file (not an external link to a .js file), you could just do a PHP print right in between your <script></script> tags. It would work with bookmarks and pasting the URL to the address bar.

For example:

<script type="text/javascript">
var get_var;
get_var = <? print $_GET['varname']; ?>;
// some jQuery code here
</script>

This should only be used as a proof of concept. This is vulnerable to XSS attacks, and should not be used in production. This list of XSS prevention techniques is a good place to start (but outside the scope of the OP's question).

You're looking for how to get values from the query string. Here's pretty much the same question:

Perhaps a plugin like jQuery.url.js would work or maybe Url parser.
