两个页面js方法兼容

 1 //Js获取Url参数
 2 function request(paras) {
 3     var url = location.href;
 4     var paraString = url.substring(url.indexOf("?") + 1, url.length).split("&");
 5     var paraObj = {};
 6     for (i = 0; j = paraString[i]; i++) {
 7         paraObj[j.substring(0, j.indexOf("=")).toLowerCase()] = j.substring(j.indexOf("=") + 1, j.length);
 8     }
 9     var returnValue = paraObj[paras.toLowerCase()];
10     if (typeof (returnValue) == "undefined") {
11         return "";
12     } else {
13         return returnValue;
14     }
15 }

1 //获取url中的参数
2 var request =
3 {
4     QueryString: function (val) {
5         var uri = window.location.search;
6         var re = new RegExp("" + val + "=([^&?]*)", "ig");
7         return ((uri.match(re)) ? (uri.match(re)[0].substr(val.length + 1)) : null);
8     }
9 };

1 if (typeof (request) == "undefined") {
2     request = function () { };
3 }
4 request.QueryString = function (val) {
5     var uri = window.location.search;
6     var re = new RegExp("" + val + "=([^&?]*)", "ig");
7     return ((uri.match(re)) ? (uri.match(re)[0].substr(val.length + 1)) : null);
8 }
