postal.dom

postal.dom binds a DOM event to a postal channel/topic so that when the DOM event is triggered, a postal message will be published.

Postal message data comes from two sources: data-postal-* attributes on the DOM element, and/or a data attribute provided on the publication hash passed to postal.dom.on.

postal.dom may be used in the browser with require.js. A non-require version will be available soon.

Prereqs

postal.dom requires:

• jquery
• underscore
• require.js
