How to get URL parameter using jQuery or plain JavaScript?

Question

I have seen lots of jQuery examples where parameter size and name are unknown.

My URL is only going to ever have 1 string:

http://example.com?sent=ye

Another solution that uses jQuery and JSON, so you can access the parameter values through an object.

var loc = window.location.href;
var param = {};
if(loc.indexOf('?') > -1)
{
    var params = loc.substr(loc.indexOf('?')+1, loc.length).split("&");

    var stringJson = "{";
    for(var i=0;i

Assuming your URL is http://example.com/?search=hello+world&language=en&page=3

After that it's only a matter of using the parameters like this:

param.language

to return

en

The most useful usage of this is to run it at page load and make use of a global variable to use the parameters anywhere you might need them.

If your parameter contains numeric values then just parse the value.

parseInt(param.page)

If there are no parameters param will just be an empty object.
