CKEditor 4.8.0版本focusout事件绑定无效，求解决方案

Hey there, let's work through why your focusout event isn't firing for the CKEditor instance tied to note-content. Since you can already use getData() and setData() without issues, we know the editor instance is correctly referenced—so the problem is likely with how or when you're binding the event.

Here are a few targeted solutions to try:

1. Use CKEditor's Native blur Event Instead #

CKEditor 4 has a built-in blur event for editor instances, which is often more reliable than directly using focusout on the instance itself. Give this a shot:

CKEDITOR.instances['note-content'].on('blur', function() {
  alert('ready');
});

2. Bind the Event After Editor Initialization #

If you're trying to attach the event before the editor is fully loaded, it might not stick properly. Wrap your event binding in the instanceReady listener to guarantee the editor is ready:

CKEDITOR.on('instanceReady', function(event) {
  const editor = event.editor;
  // Target only your specific editor instance
  if (editor.name === 'note-content') {
    editor.on('blur', function() {
      alert('ready');
    });
  }
});

3. Target the Editor's Content Body Directly #

CKEditor uses an iframe for its content area, so the focusout event might be happening inside that iframe rather than on the main editor instance. Use the contentDom event to access the iframe's body and bind the event there:

CKEDITOR.instances['note-content'].on('contentDom', function() {
  const editableBody = this.editable().getDocument().getBody();
  this.editable().attachListener(editableBody, 'focusout', function() {
    alert('ready');
  });
});

The contentDom event fires when the editor's inner content DOM (the iframe's content) is fully loaded, so this ensures you're attaching the event to the exact element that receives focus when editing.
