Hello,

How to get the query string in javascript?

Like this:

Code: 
<script type="text/javascript">
function getp(){
var p = ????GET P????
document.write('this is ' + p);
}
</script>

<div onclick="getp()">Click to show p</div>

If this website was www.example.com/index.php?p=fun then 'This is fun' had showed up..


How can I get this work?

First step. To find the full URL of the page, use document.location
HTML: 
<html>
<head><title>Test</title>

function qstring(){
   var q = document.location ;
   alert( q );
}
</script>
<body>

<button onclick='qstring();' >Query String</button>
</body>
</html>

Now, you have to figure out how to get the query string from the URL.

The query string lives at window.location.search. That being said, there's a neat little function I posted over at Stack Overflow that will probably save you a lot of work. Let me know if you have any questions about it.
