PHP输出显示一秒钟

Question

我有一个网址http://www.example.com/?req=welcome.

要获取参数,req我使用PHP如下:

      echo $_GET['req'];

这将显示正文中的消息,但此输出应在一秒后消失.

我怎么做？

Answer 1

<div id='req'><? echo $_GET['req']; ?></div>

然后使用JavaScript:

window.addEventListener('load', function (){
      setTimeout(function (){
         document.getElementById('req').textContent = '';
      }, 1000); // 1000 is 1s. Set this to how many seconds you want to allow the request to be displayed for.
});
