iframe.contentWindow.document Chrome的替代？ [英] iframe.contentWindow.document Chrome alternative?

问题描述

我如何在Chrome中调用以下内容？ iframe.contentWindow.document

How would I call the following in Chrome? iframe.contentWindow.document

推荐答案

c $ c> iframe.contentWindow.document ，但是您可能会陷入一些折磨：如果文件设置为 iframe.src 属性正在本地访问（即使用file：//协议），该属性在Chrome中无法访问。如果您指定相对文件地址并尝试在不使用IIS或Apache等Web服务器的情况下（通过简单地双击它）来测试脚本，就会发生这种情况。这同样适用于 iframe.contentDocument 。

Chrome does in fact support iframe.contentWindow.document, but there's a little wrinkle that you've probably fallen prey to: if the file set to the iframe.src property is being accessed locally (i.e. using the "file://" protocol), that property is inaccessible in Chrome. This will happen if you specify a relative file address and attempt to test the script without using a web-server like IIS or Apache (by simply double-clicking it). The same also applies to iframe.contentDocument.

我碰到过类似的问题， Chrome不会接受动态附加到iframe的事件处理程序。然后我在这篇文章中发现了这个注释，并且用Apache进行了测试，嘿，它突然开始工作了。

I ran into a similar problem where, for some odd reason, Chrome would not accept event handlers dynamically attached to iframes. Then I found the note in this article, tested with Apache, and hey presto, it suddenly began to work.
