Javascript函数每X秒重新加载一次页面？

A couple of questions:

几个问题：

I've never really used JS listeners other than onclick and onkey events, so I wondered if someone could help me with what I need in order to reload the page every X seconds?

我从来没有真正使用过除了onclick和onkey事件之外的JS监听器，所以我想知道是否有人可以帮我解决我需要的每隔X秒重新加载页面的问题？
Secondly, the page contains bare minimum, literally just one input box. Do I still need to include the html head and body?

其次，页面包含最小的，实际上只有一个输入框。我还需要包含html头部和身体吗？

You don't need Javascript for this simple function. Add in the page header:

这个简单的功能你不需要Javascript。添加页眉：

<meta http-equiv="Refresh" content="300">

300 is the number of seconds in this example.

300是此示例中的秒数。

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指出的那样，您还可以使用元刷新标记完成此操作：

<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，你仍然需要和标签。有些浏览器可能会在没有它们的情况下正确呈现页面，但最安全的是包含它们。
