How to retrieve the value of querystring from url using Javascript
- by ybbest
The following is a Javascript function I found on the internet , I keep here just in case I need to use it again.
function getParameterByName(name)
{
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location.search);
if(results == null)
return "";
else
return decodeURIComponent(results[1].replace(/\+/g, " "));
}
You can also add this method to jquery as below.
$.getParameterByName = function (name) {
name = name.replace( /[\[]/ , "\\\[").replace( /[\]]/ , "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(window.location.search);
if (results == null)
return "";
else
return decodeURIComponent(results[1].replace( /\+/g , " "));
};
$(document).ready(function () {
alert($.getParameterByName("id"));
});
