fruitmachine-ftdomdelegate

fruitmachine-ftdomdelegate

A ftdomdelegate FruitMachine helper.

This helper:

• Instantiates the dom-delegate when a fruitmachine module is instantiated;
• Binds that dom-delegate to the module's El when the fruitmachine module is setup;
• Unbinds the dom-delegate instance from the El when the fruitmachine module fires its teardown event;
• And destroys the dom-delegate when the fruitmachine module is destroyed.

Usage examples

var Apple = fruitmachine.define({
  name: 'apple',
  helpers: [require('fruitmachine-ftdomdelegate')],
  initialize: function() {
    this.onButtonClick = this.onButtonClick.bind(this);
  },
  setup: function() {
    this.delegate.on('click', 'button', this.onButtonClick);
  },
  onButtonClick: function() {
    this.fire('buttonclick');
  }
});

Note: as long as you properly destroy your fruitmachine modules after you're finished with them, you need not worry about detached DOM nodes because dom-delegate will ensure any event listeners added are removed when destroy is called on it.

Demonstration 'todo' app

There is a rework of the TODO example from the main fruitmachine project. You will need to clone this repository then run the following command in order to view it.

npm install

The modules that make use of the fruitmachine-ftdomdelegate helper are located here and here.
