How do I bind to itemAdded event of a drop down using jQuery

I'm adding elements to a drop down using jQuery. Currently I'm adding new items using below which is working fine:

$("#treatmentGroupDropDown").append(new Option(tempGroupName, tempGroupIndex));

However I want to create and subscribe to the itemAdded event which I've tried using the code below, but this isn't working:

$("#treatmentGroupDropDown").bind('itemAdded', funct开发者_如何学JAVAion (event, item) { alert('item added: ' + item.toString()); });

Will something like this work?

You need some thing like this -

$("#treatmentGroupDropDown").bind('itemAdded', function(event, item) {
    alert('item added: ' + $(item).val());
});

var option = new Option("Test", "Test")
$("#treatmentGroupDropDown").append(option);
$('#treatmentGroupDropDown').trigger('itemAdded', option);

This will trigger the 'itemAdded' event after the new option has been appended, passing the option object that has just been created to the function.

The bind function doesn't have any itemAdded event.

Instead, you'd better add the function you want to trigger after the statement that appended your new Option.
