var resultObj = {};
var search = window.location.search;
if(search && search.length > 1){
var search = search.substring(1);
var items = search.split('&');
for(var index = 0 ; index < items.length ; index++ ){
if(! items[index]){
continue;
}
var kv = items[index].split('=');
resultObj[kv[0]] = typeof kv[1] === "undefined" ? "":kv[1];
