url 中文乱码问题解决

function getRequest() {
       var url = window.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 ++) {
              //就是这句的问题
             theRequest[strs[i].split("=")[0］=decodeURI(strs[i].split("=")[1]);
             //之前用了unescape()
             //才会出现乱码
          }
       }
       return theRequest;
    }
