Events brick

Cross browser events plugin for lego.

Installation

with component:

$ component install bredele/events-brick

with nodejs:

$ npm install events-brick

Advantages

• clean separation of concerns

  Because you listen events directly in your HTML (dom or template), you don't need to edit both your HTML and JavaScript when you want to change something.

• Event mapping for reactive user experience

  By default, this plugin map desktop browser events (such as click, mousedown/up/move) with touch events (such as touchstart/end/move) if you are on a mobile device.

• Event delegation and filtering

Usage

First, add the plugin to your view (see lego to know more about views):

var events = require('events-brick');

view.add('data-event', events({
  handler : function() {
    //do something on click
  }
}));

Basic

See examples to see live.

<button data-event="on:click, handler">click</button>

Execute handler on click (or touchend if mobile).

<button data-event="on:click, handler, true">click</button>

Use capture.

Every handler get the event target (cross browser), the event and the anchor node as arguments.

Delegation

<ul data-event="on:click .clickable,handler">
  <li class="clickable">clickable</li>
  <li>nothing</li>
</ul>

Execute handler only when clicked on an child DOM with the class clickable.

Filtering

<input data-event="on:keypress > 13, handler">

Execute handler only when enter is pressed.

Standalone

This component is trivial enough to be reused outside of Lego.

var events = require('events-brick');

//execute obj.handler on click
events(obj).on(document.body, 'click', 'handler');
