JavaScript 獲取GET中的值

 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;
}

//將url作爲參數傳入
var strUrl='http://localhost/phone/phone.php?UserEvent=SignIn&EnterpriseID=0000011&UserName=1004';
alert (GetQueryString(str,'UserEvent'));

function GetQueryString(url,name)

var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var arr=url.split("?");
//alert(arr.length);
//alert(arr[1]);
var r = arr[1].match(reg);
if (r!=null) return unescape(r[2]); return null;
