这里是一个获取Url带Questring参数的Javascript客户端解决方案，相当于ASP的Request.QueryString，PHP的$_GET，代码如下：
|
<script language="javascript"> function GetRequest() { var url = location.search; //获取url中"?"符后的字串 var theRequest = new Object(); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("&"); for(var i = 0; i < strs.length; i ++) { theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); } } return theRequest; } </script> |
然后我们通过调用此函数获取对应参数值，以此获取url串中所带的同名参数：
|
<script language="javascript"> var Request = new Object(); Request = GetRequest(); var 参数1, 参数2, 参数3, 参数N; 参数1 = Request['参数1']; 参数2 = Request['参数2']; 参数3 = Request['参数3']; 参数N = Request['参数N']; </script> |
二、正则分析法
代码如下：
|
<script language="javascript"> function GetQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i"); var r = window.location.search.substr(1).match(reg); if (r!=null) return unescape(r[2]); return null; } alert(GetQueryString("参数名1")); alert(GetQueryString("参数名2")); alert(GetQueryString("参数名3")); </script> |
