function GetUrlMenuCode() { 
var url = window.location.href; 
var parameter = url.substring(url.indexOf('?') + 1); 
parameter = parameter.split('&'); 
var reg = /MenuCode=/g; 
var menuCode = ""; 
for (var i = 0; i < parameter.length; i++) { 
reg.lastIndex = 0; 
if (reg.test(parameter[i])) { 
menuCode = parameter[i].replace("MenuCode=", ""); 
break; 
} 
} 
return menuCode; 
}
