I'm using select2 and in my site. I need to know at some point if the dropdown is open or closed. I've studied the documentation but I don't see how this can be done. For example, something like this would be nice:
if ($('select').select2('isOpen') === true) { ... }
Any suggestions?
By doing some code inspection, it looks like select2-dropdown-open is the class that it adds. But there is an event select2-open in the documentation that fires when the dropdown is open. You can use that to set a variable, or perform an action (also select2-close).
You can do something like this:
$(#e11).on(select2-open, function() {
$(this).data(open, true);
});
$(#e11).on(select2-close, function() {
$(this).data(open, false);
});
if ($(#e11).data(open)) {
//do something
}
2018 Edit
It appears that the names of the events have been updated since 2014. See user1636505's answer below.
