问题描述

我有一个iframe，我想每15秒刷新一次，但我不知道该怎么做或者甚至可能。如果是，我将如何在不使用JavaScript的情况下这样做。如果需要JavaScript，请发布我将如何在JavaScript中执行此操作。谢谢。

I have an iframe which I would like to refresh every fifteen seconds, but I'm not sure how to do this or if it is even possible. If it is, how would I go about doing this without the use of JavaScript. If JavaScript is necessary then please post how I would do it in JavaScript. Thank you.

推荐答案

您可以使用元标记在包含的HTML文件的HEAD元素内实现此目的在iframe内：

You might be able to achieve this using a meta tag, inside the HEAD element of the HTML file being included inside the iframe:

<meta http-equiv="refresh" content="5" />

这将每5秒刷新一次页面。请参阅维基百科条目。

This will refresh the page every 5 seconds. See the Wikipedia entry.

但是，使用JavaScript，这是要走的路：

However, using JavaScript, this is the way to go:

function reloadIframe() {
    var iframe = document.getElementById('my-iframe');
    iframe.src = "http://some/url/";
    setTimeout("reloadIframe()", 5000);
}
window.onload = reloadIframe;

这将重新加载ID my-iframe 每隔五秒，将其指向 http：// some / url 。

This will reload the iframe with ID my-iframe every five seconds, by pointing it to http://some/url.
