获取url中的参数值

一、简单方便

function getQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); var r = window.location.search.substr(1).match(reg); if (r != null) return decodeURI(r[2]); return null; }

二、麻烦

var urlparam = window.location.search; if (urlparam.indexOf("XXX") > 0 ) { var index = urlparam.indexOf("XXX"); var strXXX = urlparam.substring(index + 3); var str = strXXX.substring(0, strXXX.indexOf("&")); }
