使用JavaScript获得URL在参数值

方法一：

function getUrlParam(name) { 

    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); //构造一个含有目标參数的正則表達式对象 

    var r = window.location.search.substr(1).match(reg); //匹配目标參数 

    if (r != null) return unescape(r[2]); return null; //返回參数值 

}

方法二：

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;

}

var Request = new Object();

Request = GetRequest();

var 參数1,參数2,參数3,參数N;

參数1 = Request['參数1'];

參数2 = Request['參数2'];

參数3 = Request['參数3'];

参数N = Request['参数N'];
