PHP：在指定的时间内回显消息

本文介绍了PHP：在指定的时间内回显消息的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想显示一个字符串您的状态已发布，持续约3秒钟，而不是我希望它消失的时间。

I want to display a string "Your status has been posted" for something around 3 or so seconds than I want it to go away.

截至目前我有一个新闻提要，用户可以在其中发布消息，并在它们发布后回显该文本字符串，直到重新输入URL。有人有什么建议吗？

As of right now I have a news feed where the user can post messages and after they post it echoes that string of text until the url is re-enetered. Does anyone have any suggestions?

if ($_POST['submit']) { $body = $_POST['body']; if ($body) { include ('connect.php'); $date = date("Y-m-d"); $email = $_SESSION['email']; $who = mysql_query("SELECT firstname FROM people WHERE email = $email"); $insert = mysql_query(" INSERT INTO status VALUES('','$email','$body','$date')"); echo ('Your status has been posted <p></p>'); } else echo 'Status required to post into news feed! <p></p>'; } ?>

状态：

感谢您的帮助！

推荐答案

您需要添加一些JavaScript才能执行此操作。以下是入门的概述：

You need to add some JavaScript to do this. Here is an outline to get you started:

<p id="info-message">Your status has been posted</p> <script> setTimeout(function(){ document.getElementById('info-message').style.display = 'none'; /* or var item = document.getElementById('info-message') item.parentNode.removeChild(item); */ }, 3000); </script>

另外，您可能希望淡出效果。为此，我建议使用jQuery或Scriptaculous之类的库。

Also you may want fade-out effects. For that I'd recommend using a library like jQuery or Scriptaculous.

哦，顺便说一下，您的脚本容易受到 SQL注入的影响。 >始终转义您的查询参数（或使用准备好的查询）！

Oh, by the way, your script is vulnerable to SQL injection. Always escape your query parameters (or use prepared queries)!
