note event-hub depends on classcaps.

Usage

<script src="path/to/class-component.js"></script>
<script src="path/to/event-hub.js"></script>
 
 
<div class="event-hub" channel="click">
 
    <div>DIV 1</div>
 
    <div class="sub-click">DIV 2</div>
 
    <div>DIV 3</div>
 
</div>

The channel attribute specify which events are the channel of the .event-hub. (If you want to set multiple channels, set them like click mouseover (in space-separated form)).

The sub-click class on the 2nd element in the .event-hub means that it subscribes to click event of the .event-hub.

With the above settings, all the click events which occur under the .event-hub is published to the 2nd div.

See the DEMO.

API

<tag class="event-hub" channel="ch0 ch1 ... ch_N"></tag>
  • @class event-hub is the component name. You need to specify the class name in dom.
  • @param {string[]} ch0, ch1,..., ch_N The channel which the event hub brokes.

If the event ch_i bubbles up to the above event-hub dom, then it dispatches the event to its children which has sub-ch_i class in it.

const { def } = require('classcaps')
const EventHub = require('event-hub')
