带有计时器的JavaScript警报框 [英] JavaScript alert box with timer

问题描述

我想显示警告框但是在一定的时间间隔内。是否可以在JavaScript中使用？

I want to display the alert box but for a certain interval. Is it possible in JavaScript?

推荐答案

如果您希望在某段时间后出现警报，则可以使用以下代码：

If you want an alert to appear after a certain about time, you can use this code:

setTimeout(function() { alert("my message"); }, time);

如果您希望在指定的时间间隔过后出现并消失警报，那么您就出局了好运触发警告后，浏览器将停止处理javascript代码，直到用户单击确定。当显示确认或提示时，会再次发生这种情况。

If you want an alert to appear and disappear after a specified interval has passed, then you're out of luck. When an alert has fired, the browser stops processing the javascript code until the user clicks "ok". This happens again when a confirm or prompt is shown.

如果你想要出现/消失的行为，那么我建议使用像 jQueryUI的对话框小工具之类的东西。 。下面是一个关于如何使用它来实现这种行为的快速示例。

If you want the appear/disappear behavior, then I would recommend using something like jQueryUI's dialog widget. Here's a quick example on how you might use it to achieve that behavior.

var dialog = $(foo).dialog('open');
setTimeout(function() { dialog.dialog('close'); }, time);
