javascript - 未触发 Angular contenteditable 更改事件

Question

我在对 execCommand 上的 Controller 范围应用直接更改时遇到问题。

在找到的 contenteditable 指令中未触发 change 事件 here我必须模糊 div 才能应用更改。这是一个错误还是还有其他事情要做？

这是我的 jsfiddle用于测试。

=== 编辑 ===

大胆的 execCommand 正在 dom 上工作，但它不会直接更新 Controller 范围，除非事件被触发，如 keyup on the field 或 blur。

Answer 1

change事件不会在对 DOM 元素的值进行所有更改时触发。解决方案是使用 input事件。

  element.on('input', function() {
      scope.$evalAsync(read);
  });

change

Unlike the input event, the change event is not necessarily fired for each change to an element's value.

input

The DOM input event is fired synchronously when the value of an <input> or <textarea> element is changed. Additionally, it fires on contenteditable editors when its contents are changed. In this case, the event target is the editing host element. If there are two or more elements which have contenteditable as true, "editing host" is the nearest ancestor element whose parent isn't editable.
