修改密码成功后，倒计时三秒后，跳转到登录页面

简单描述：需求上说，修改密码完成之后，要有个倒计时3秒，倒计时完成之后，才返回到登录页面，而不是修改完密码，立即返回到登录的页面

代码：

//html代码
<div class="portlet light bordered" id="loginbox">
       <div class="tab-content">
           <div class="row">
               <form action="" class="horizontal-form" method="post" id="searchForm" autocomplete="off">

总结：代码就这一点，主要用到了 window.setInterval(code, delay), 具体了解请查阅https://developer.mozilla.org/zh-CN/docs/Web/API/Window/setInterval
