JS獲取url參數值的兩種方式

1. 正則分析法

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; 
} 

調用方法：

alert(GetQueryString("參數名1"));alert(GetQueryString("參數名2")); 
alert(GetQueryString("參數名3")); 

1. 方法二

<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> 

調用方法：

<Script language="javascript"> 
	var Request = new Object(); 
	Request = GetRequest(); 
	var 參數1,參數2,參數3,參數N; 
	參數1 = Request['參數1']; 
	參數2 = Request['參數2']; 
	參數3 = Request['參數3']; 
	參數N = Request['參數N']; 
</Script>
