Clear select2 without triggering change event
提问by Ryan Gill
I have a select2 input that I'm using and on 'change' I'm grabbing the values and performing an action. I'm trying to clear that select2 without triggering a change event. Is this possible?
我有一个我正在使用的 select2 输入,并且在“更改”时我正在获取值并执行操作。我试图在不触发更改事件的情况下清除该 select2。这可能吗?
To clear the select2 I'm using the following code:
要清除 select2 我使用以下代码:
$docInput.select2('data', null);
This clears the input as desired, but also triggers a change event which runs through my other code. There must be a way to silence the trigger. Any ideas?
这会根据需要清除输入,但也会触发通过我的其他代码运行的更改事件。必须有一种方法可以使触发器静音。有任何想法吗?

I believe all you need is:
我相信您只需要:
$docInput.select2('data', null, false);
$docInput.select2('data', null, false);

You can use the following with Select2 4.x
您可以在 Select2 4.x 中使用以下内容
$docInput.val(null).trigger('change.select2');
