js获取地址栏参数2种最简单方法

//普通参数
function GetQueryString(name)
{
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r!=null)return unescape(r[2]); return null; ----------------------->return为""也是可以的
}//中文参数（防止乱码的）
function GetQueryString(name)
{
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r!=null)return decodeURI(r[2]); return null; ----------------------->return为""也是可以的

}

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;
} //调用方法
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'];
