删除元素时的CKEditor事件？ [英] CKEditor event when deleting an element?

问题描述

在JavaScript（或CKEditor）中有一种方法来检测图像从CKEditor中移除的时间。
我需要一个与图片一起插入的字幕元素，但是一旦我删除了图片，该标题也应该删除。

Is there a way in JavaScript (or CKEditor) to detect when an image is removed from CKEditor. I need it for a caption element which is inserted together with the image, but once I delete the image, the caption should be deleted aswell.

任何帮助

推荐答案

没有像 onDelete 或 onImageRemovedFromContent 。但有少数事件可以帮助你。

There are no special event like a onDelete or onImageRemovedFromContent. But there are few events that can help you.

editor.on('afterUndoImage', function( e ){ ... } )

但 afterUndoImage 仅在上激活 $ c>命令，不会在手动删除元素时触发。

But afterUndoImage fires only on Undo command, does not fires on manual deleting of elements.

editor.on('afterCommandExec', function( e ){ ... } )

CKEditor使用 execCommand （大多数），所以对许多内容的变化，所以你可以检查差异与regex例如。火灾。

CKEditor changes content with execCommand (mostly), so that fires on many content's change, so you can check the diff with regex for example.

也可以使用插件 onchange 检测内容的更改，它将 onUndo ， onRedo ， afterCommandExec 等。

Also you can use plugin onchange to detect the changes of contents, it combines onUndo, onRedo, afterCommandExec, etc.
