前端 js 实现简单 表单提交

1. 登录页 验证用户身份,登录成功之后等待一定秒数,跳转到操作页面

<html>   <head>     <title>Login.html</title>          <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">     <meta http-equiv="description" content="this is my page">     <meta http-equiv="content-type" content="text/html; charset=UTF-8">          <!--<link rel="stylesheet" type="text/css" href=http://www.mamicode.com/"./styles.css">-->     <script type="text/javascript">       function checkuser() {          if($(uname == "lala") && $(pwd) == "123") {            return true;          }else {             return false;          }       }              function $(id) {         return document.getElementById(id).value;       }      </script>   </head>      <body>     <form action="ok.html">       u:<input type="text" id="uname"/><br>       p:<input type="password" id="pwd"/><br>       <input type="submit" value=http://www.mamicode.com/"登录" onclick="return checkuser()"/>     </form>   </body> </html> 

2. 登录成功页面中,等待5秒

<html>   <head>     <title>ok.html</title>          <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">     <meta http-equiv="description" content="this is my page">     <meta http-equiv="content-type" content="text/html; charset=UTF-8">          <!--<link rel="stylesheet" type="text/css" href=http://www.mamicode.com/"./styles.css">-->     <script type="text/javascript">         function tiao() {           clearInterval(mytime);           window.open("manage.html","_self");         }                  setTimeout("tiao()",5000);                  function changeSec() {            //得到myspan值            $(myspan).innerText=$(myspan).innerText-1;         }                   function $(id) {         return document.getElementById(id);       }         var mytime = setInterval("changeSec()",1000);     </script>   </head>      <body>     登录成功,<span id="myspan">5</span>秒后自动跳转到管理页面   </body> </html> 

3. 写一个manage.html 即可
