Javascript function to reload a page every X seconds?
提问by Tom
A couple of questions:
几个问题：
I've never really used JS listeners other than
onclickandonkeyevents, so I wondered if someone could help me with what I need in order to reload the page every X seconds?Secondly, the page contains bare minimum, literally just one input box. Do I still need to include the html
headandbody?
除了
onclick和onkey事件之外，我从未真正使用过 JS 侦听器，所以我想知道是否有人可以帮助我解决我需要的每 X 秒重新加载页面的问题？其次，页面包含最少的内容，实际上只有一个输入框。我还需要包含 html
head和body吗？

You don't need Javascript for this simple function. Add in the page header:
这个简单的功能不需要 Javascript。在页眉中添加：
<meta http-equiv="Refresh" content="300">
300 is the number of seconds in this example.
300 是本例中的秒数。

To reload the page after 5 seconds (5000 milliseconds) using JavaScript, add the following to the bottom of the page:
要使用 JavaScript 在 5 秒（5000 毫秒）后重新加载页面，请将以下内容添加到页面底部：
<script type="text/javascript">
setTimeout(function () { location.reload(true); }, 5000);
</script>
As Greg Hewgill notes, you can also accomplish this with the meta refresh tag:
正如 Greg Hewgill 所指出的，您还可以使用元刷新标签来完成此操作：
<meta http-equiv="Refresh" content="5">
Strictly speaking, you do still need <html>and <body>tags. Some browsers may render the page correctly without them, but your are safest to include them.
严格来说，你仍然需要<html>和<body>标签。某些浏览器可能会在没有它们的情况下正确呈现页面，但包含它们是最安全的。
