对于每次从地址栏获取信息，自己每次拆分，很少麻烦，在同事的启发下，封装一个获取地址栏信息的函数

var xinXi = (function(){

        var url = window.document.location.href.toString();

        var u = url.split("?");

        if(typeof(u[1]) == "string"){

                u = u[1].split("&");

                var get = {};

                for(var i in u){

                        var j = u[i].split("=");

                        get[j[0]] = j[1];

                }

                return get;

        } else {

                return {};

        }

})();
