get url variables by using this method:
function sc_getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}

Example calling:

var calltype = sc_getUrlVars()["calltype"];
if(calltype){
if(calltype == 'editpaymentmethod'){
