  <label class="input-group-addon" @*style="width: 120px;"*@ id="frameGroupCode"></label>
  <input class="form-control" type="text" id="frameGroupName" style="">
</div>

推荐答案

看看 change事件的文档.它仅针对特定类型的元素触发:

Take a look at the documentation for the change event. It only fires for specific types of elements:

当用户提交对元素的值的更改时，将触发<input>，<select>和<textarea>元素的change事件...

The change event is fired for <input>, <select>, and <textarea> elements when a change to the element's value is committed by the user...

您将不能对不是上述类型之一的元素使用change事件.

You won't be able to use the change event for an element that is not one of the previously mentioned types.

如果您还可以通过其他方式知道特定元素的编辑已完成，则必须触发您自己的事件-可能使用

If you have some other way of knowing that editing has finished of a specific element, you'll have to fire your own event - possibly using the blur event on the element that was used to change the value. The blur event is triggered when the selected element looses focus such as when a user clicks (or tabs) out of an input element.
