Hydra.js and Delegate module extension.

Delegate is an extension that register a base module to delegate events to document instead of attach events to different elements in DOM.

This module will save a lot of memory in your applications.

Requirements

You will need to load it after Hydra.js and after all the files stored in the utilities folder in this repo.

Add it in your application

We have created Delegate to be used with and without require.js

Simple

<script type="text/javascript" src="Hydra.js"></script> // Crossbrowsing Array.prototype.indexOf implementation <script type="text/javascript" src="utilities/array_indexOf.js"></script> // Crossbrowsing function to convert NodeList to Array <script type="text/javascript" src="utilities/nodelist_to_array.js"></script> // Crossbrowsing function to attach events to DOM elements. <script type="text/javascript" src="utilities/events.js"></script>

Using require.js

require('utilities/events', 'utilities/array_indexOf', 'utilities/nodelist_to_array', 'delegate');

Usage

To use Delegate you only need to extend the 'delegate-base-module'. See extend docs in http://tcorral.github.io/Hydra.js/#documentation.

Extending 'delegate-base-module'

Hydra.module.extend( 'delegate-base-module', 'new-module-with-delegation', function ( oBus ) { return { domEvents: { 'click .test': function ( eEvent ) { //The context of this function is the element that we expect trigger the event. } }, init: function () { this.__super__.__call__('init'); // Needed to execute the delegation of events. // Some start code. }, onDestroy: function () { // Some stop code. this.__super__.__call__('onDestroy'); // Needed to execute the unbind of events. } }; } );
