js獲取url引數值的兩種方式

 

方法一：正則分析法 

複製程式碼程式碼如下:
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")); 

方法二

 

複製程式碼程式碼如下:
<Script language="javascript"> 
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; 
} 
</Script> 

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']; 
</Script>
