How to capture event when allowClear option of select2 is chosen?

问题

I've tried to capture select2:clearing event

$("#my-select").on("select2:clearing", function (e) {
    console.log('cleared');
});

(jsfiddle)

but it is not fired. I've also tried other versions (like select2:removed etc., see another question with similar problem), but it also doesn't work.

I use select2 4.0.0-beta2.

回答1:

The changelog of select2 4.0.0-beta2 states:

Removed events

select2-clearing - Use select2:unselecting instead

回答2:

This works:

$("#my-select").on("select2:unselecting", function(e) {

 });

回答3:

$("#my-select").on("select2:select select2:unselecting", function(e) {
   //do something here
 });
