Crisp.EventJS

Object event with repeater, picker and optional asynchronous.

var myObject = Crisp.utilCreate({ ns: 'util.event' }).objIni();

myObject.eventListener({
  listen: function( e ) {
    console.log('Listen');
  }
});
console.log('Wait');

myObject.eventTrigger();

// logs:
// Wait
// Listen

Getting Started

Server-Nodes

Use Node Package Manager (npm) to install crisp-event for Node.js and io.js

$ npm install crisp-event

// use package
require("crisp-event");

or use the OpenCrisp UtilJS wraper

$ npm install crisp-util

// use package
require("crisp-util");

Web-Clients

Use Bower to install crisp-event for Browsers APP's and other front-end workflows.

$ bower install crisp-event

<!-- use package -->
<script type="text/javascript" src="dist/crisp-event.min.js"></script>

or use the OpenCrisp UtilJS wraper

$ bower install crisp-util

<!-- use package -->
<script type="text/javascript" src="dist/crisp-util.min.js"></script>

Development

Use Git to clone Crisp.EventJS from GitHub to develop the repository with Grunt

# Clone:
$ git clone https://github.com/OpenCrisp/Crisp.EventJS.git

# Build: test, concat, test, minify, test
$ grunt

# Test: original sourcecode for developer (included in build)
$ grunt t

# Run all test-scripts on Unix
$ sh grunt-tests.sh

Usage

How to use Crisp.EventJS with JavaScript.

Crisp.defineEvent()

How to use Crisp.defineEvent( object [, option ]) module.

var myObject = {};

// initialice event property functions on myObject
Crisp.defineEvent( myObject );

// or with manual property name of event and parent 
Crisp.defineEvent( myObject, {
    // default: __event__
    event: '__myevent__',       // manual set the name of event cach
    // default: __parent__
    parent: '__myparent__'      // manual set the name of parent reference
});

Crisp.utilCreate()

How to use Crisp.utilCreate( option ) with util.event namespace.

var myObject = Crisp.utilCreate({
    ns: 'util.event'
}).objIni();

EventJS function

.eventListener()

How to use .eventListener( option ) on myObject

// listen for all triggert events
myObject.eventListener({
  listen: function( e ) {}
});

• option
  • listen - callback function
  • self - alternate for apply thisArg
  • async - acitvate asynchronous callback
  • action - namespace OR RegExp filter
  • path - like OR RegExp filter
  • noteList - like filter for eventPicker notes
  • noteAction - namespace OR RegExp filter for eventPicker notes
  • notePath - like OR RegExp filter for eventPicker notes

option.self (eventListener)

works with .eventTrigger() and .eventPicker()

// set self as alternate for apply thisArg
var thisArg = {};
myObject.eventListener({
  self: thsiArg,
  listen: function( e ) {
    this === thisArg;  // true
  }
});

option.async (eventListener)

works with .eventTrigger() and .eventPicker()

// set asynchronous callback for listen:function
myObject.eventListener({
  async: true,
  listen: function( e ) {}
});

option.action (eventListener)

works with .eventTrigger() and .eventPicker()

// set right namespase string filter
myObject.eventListener({
  action: 'insert',
  listen: function( e ) {}
});

// set an expandable RegExp filter like action:'insert'
myObject.eventListener({
  action: /(^|\s)insert($|\s|\.)/,
  listen: function( e ) {}
});

// set multi right namespase string filter with space seperator
myObject.eventListener({
  action: 'insert update',
  listen: function( e ) {}
});

// set an expandable RegExp filter like action:'insert update'
myObject.eventListener({
  action: /(^|\s)(insert|update)($|\s|\.)/,
  listen: function( e ) {}
});

option.path (eventListener)

works with .eventTrigger() and .eventPicker()

// set 
myObject.eventListener({
  action: /(^|\s)(insert|update)($|\s|\.)/,
  listen: function( e ) {}
});

option.noteList (eventListener)

works with .eventPicker()

// filter notes in specified list 
myObject.eventListener({
  noteList: 'merge',
  listen: function( e ) {}
});

option.noteAction (eventListener)

works with .eventPicker()

// set filter of note action
myObject.eventListener({
  noteAction: 'delete',           // or RegExp like option.action
  listen: function( e ) {}
});

option.notePath (eventListener)

works with .eventPicker()

// set filter of note path
myObject.eventListener({
  notePath: 'doc.b',
  listen: function( e ) {}
});

myObject.a = myChild;

myChild.eventListener({

    }
});

myObject.eventListener({
    listen: function( e ) {
