js获取URL传参

var GetRequest=function() { 
        var url = location.search; //获取url中"?"符后的字串 
        var theRequest = new Object();
        if (url.indexOf("?") != -1) {
            var str = url.substr(1);
            strs = str.split("&");
            for (var i = 0; i < strs.length; i++) {
                theRequest[strs[i].split("=")[0]] =         
                unescape(strs[i].split("=")[1]);
             }
        }
        return theRequest;
    } 

var Requests = new Object();
Requests = GetRequest();
//取值:****.html？name=123
//即获得Requests["name"]的值为123
