How to get "GET" request parameters in JavaScript? [duplicate]

Question

How to get "GET" variables from request in JavaScript?

Does jQuery or YUI! have this feature built-in?

Answer 1

Update June 2021:

Today's browsers have built-in APIs for working with URLs (URL) and query strings (URLSearchParams) and these should be preferred, unless you need to support some old browsers or Opera mini (Browser support).

Original:

All data is available under

window.location.search 

you have to parse the string, eg.

function get(name){    if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))       return decodeURIComponent(name[1]); } 

just call the function with GET variable name as parameter, eg.

get('foo'); 

this function will return the variables value or undefined if variable has no value or doesn't exist

Answer 2

You could use jquery.url I did like this:

var xyz = jQuery.url.param("param_in_url"); 

Check the source code
