访问iframe中的javascript ckeditor对象 [英] access javascript ckeditor object within an iframe

问题描述

假设我有一个iframe的页面，并且在iframe中有一个ckeditor实例，我想从包含的页面中销毁。

Lets say I have a page with an iframe and within the iframe I have a ckeditor instance that I want to destroy from the containing page.

我通常会尝试像这样：

var iframe_document = document.getElementById("iframe_id").contentWindow.document;
for(var i in iframe_document.CKEDITOR.instances)
  iframe_document.CKEDITOR.instances[i].destroy();

但是看起来ckeditor实例不能以这种方式访问​​。

However it appears that the ckeditor instance can not be accessed this way. Is it possible to destroy the instance from outside the document similar to this?

为了澄清确切的错误是无法读取未定义的属性实例

To clarify the exact error is "cannot read property 'instances' of undefined"

推荐答案

全局变量属于窗口，而不是文档，请尝试：

Global variables belong to the window, not to the document so try this:

var iframe_CKEDITOR = document.getElemenyById("iframe_id").contentWindow.CKEDITOR;
for(var i in iframe_CKEDITOR.instances)
  iframe_CKEDITOR.instances[i].destroy();
