js獲取url引數的方法有很多。

1.正則分析

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; 
}

呼叫方法： alert(GetQueryString("引數名1"));alert(GetQueryString("引數名2")); alert(GetQueryString("引數名3"))；

2.

function GetRequest() { 
var url = location.search; //獲取url中"?"符後的字串 
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; 
} 
 

呼叫方法： <Script language="javascript"> var Request = new Object(); Request = GetRequest(); var 引數1,引數2,引數3,引數N; 引數1 = Request['引數1']; 引數2 = Request['引數2']; 引數3 = Request['引數3']; 引數N = Request['引數N'];
