If you mean selecting with the mouse, you can use mouseup
. However, it will fire when the select box is being opened as well, so you’ll need to keep track of the amount of times it was fired (even: select is being opened, odd: select is being closed): http://jsfiddle.net/T4yUm/2/.
$("select").mouseup(function() {
var open = $(this).data("isopen");
if(open) {
alert(1);
}
$(this).data("isopen", !open);
});
