What does this code GetParameterValues function do?

Question

I would like to know what this code does? I am using it almost all the time but I don't know what it does.

   function GetParameterValues(param) {
            var url = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
            for (var i = 0; i < url.length; i++) {
                var urlparam = url[i].split('=');
                if (urlparam[0] == param) {
                    return urlparam[1];
                }
            }
        }

And is there any other function which could get query string parameter directly ?

Hi @developer sp1 ,

It extracts one named parameter from the QueryString (URL), for example:

http://domainname.com/page.aspx?parameter1=xxx&parameter2=yyy  
  
var value=getQueryStringParameter('parameter1');  

In SharePoint environment, you can use JsRequest.js to achieve the same function like this:

JSRequest.EnsureSetup();  
var value=JSRequest.QueryString['parameter1'];
