Clear select2 without triggering change event

问题

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?

To clear the select2 I'm using the following code:

$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?

回答1:

I believe all you need is:

$docInput.select2('data', null, false);

回答2:

You can use the following with Select2 4.x

$docInput.val(null).trigger('change.select2');
