调用 pagebeforechange方法
$(document).bind("pagebeforechange", function (e, data) {
if (typeof data.toPage === "string") {
var u = $.mobile.path.parseUrl(data.toPage);
var flag = Mobile.Page.checkurl(u.hrefNoHash);//执行验证
if (!flag) {
localStorage.setItem("url",u.hrefNoHash);
data.toPage = "login.html";
}}
