About

Is some other jQuery library doing things behind your back? Manipulating the DOM without giving you proper events to respond to? Worry no more! With jquery-listener, you can easily listen to any jQuery method and respond accordingly!

Usage

var $ = require('jquery');
require('jquery-listener'); // === $.listener

$.listener.on('val');

// only listen to the one argument version
$('#some-input').on('listener:val:1', function()
{
	// so we don't overflow when using the zero argument version here
	console.log('#some-input changed value to: ' + $('#some-input').val());
});

$('#some-input').val('some text');
// outputs: '#some-input changed value to: some text'

Motivation

One day, while working with jQuery UI's autocomplete widget, I was frustrated while attempting to respond to changes to the underlying text input's value. It didn't seem to have enough events to respond to all changes. Then I thought: "But this is a jQuery library! Surely they must be updating the value using jQuery's val method!". And so jquery-listener was born!

Is this the proper way to go about solving the problem? Probably not... I don't know. But regardless, I feel as if this power is useful. At the very least as a debugging tool. Remember young grasshopper: with great power, comes great responsibility. -_-
