是否body.onload等待的IFrame？ [英] Does body.onload wait for IFrames?

问题描述

我知道的onload 活动等待页面资源烧制之前加载 - 图片，样式等

I know that onload event waits for page resources to load before firing - images, stylesheets, etc.

但是，这是否包括页面内的IFrame？换句话说，它是保证所有的子帧的的onload 取值将总是先于父母的火呢？

But does this include IFrames inside the page? In other words, is it guaranteed that all the child Frames' onloads will always fire before the parent's does?

另外，请让我知道如果浏览器的行为之间变化。

Also, please let me know if behavior varies between browsers.

推荐答案

正如我在我的网页看到，每个iframe中得到了独立的onload，和顶架的onload不等待的iframe火。

As I see on my pages, each iframe got independent onload, and top-frame onload doesn't wait for iframes to fire.

我在我的网站有GIF / PNG横幅，有时加载很慢，所以我把它们放进iframe中，这让整个网站和onload事件工作得更快。

I got gif/png banners on my site that sometimes loads very slowly, so I put them into iframe and that made whole site and onload event to work faster.
