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=yes 

I just want to detect:

1. Does sent exist?
2. Is it equal to "yes"?

Best solution here.

var getUrlParameter = function getUrlParameter(sParam) {     var sPageURL = window.location.search.substring(1),         sURLVariables = sPageURL.split('&'),         sParameterName,         i;      for (i = 0; i < sURLVariables.length; i++) {         sParameterName = sURLVariables[i].split('=');          if (sParameterName[0] === sParam) {             return sParameterName[1] === undefined ? true : decodeURIComponent(sParameterName[1]);         }     }     return false; }; 

And this is how you can use this function assuming the URL is,
http://dummy.com/?technology=jquery&blog=jquerybyexample.

var tech = getUrlParameter('technology'); var blog = getUrlParameter('blog');
