js获取地址栏参数2种最简单方法
NO1:(本人最喜欢)
//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
}
// 调用方法
alert(GetQueryString(
"参数名1"
));
alert(GetQueryString(
"参数名2"
));
alert(GetQueryString(
"参数名3"
));
第二种:
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'];
