How to trigger event in JavaScript?

Question

I have attached an event to a text box using addEventListener. It works fine. My problem arose when I wanted to trigger the event programmatically from another

Answer 1

if you use jQuery, you can simple do

$('#yourElement').trigger('customEventName', [arg0, arg1, ..., argN]);

and handle it with

$('#yourElement').on('customEventName',
   function (objectEvent, [arg0, arg1, ..., argN]){
       alert ("customEventName");
});

where "[arg0, arg1, ..., argN]" means that these args are optional.
