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         


        

Answer 1

This is based on Gazoris's answer, but URL decodes the parameters so they can be used when they contain data other than numbers and letters:

function urlParam(name){
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
    // Need to decode the URL parameters, including putting in a fix for the plus sign
    // https://stackoverflow.com/a/24417399
    return results ? decodeURIComponent(results[1].replace(/\+/g, '%20')) : null;
}
