behave-ui-hotkeys

A Marionette Behavior that allows you to add hotkey functionality to any view.

Usage:

npm install --save behave-ui-hotkeys

Then just require and use as you would any other behavior:

var Hotkeys = require('behave-ui-hotkeys'),
    _ = require('underscore');
 
var View = Marionette.ItemView.extend({
    template: _.template('<h1>Hotkeys!!</h1>'),
    behaviors: {
        Hotkeys: {
            behaviorClass: Hotkeys,
            hotkeys: {
               'cmd:alt:y': 'viewMethod'
            },
            attachToDocument: false
        }
    },
    initialize: function() {
        this.on('hotkey:cmd:alt:y', function() {
            // hotkey fired!
        });
    },
    viewMethod: function(e) {
        // hotkey fired!
    }
});

NOTES:

• You can use only one code (f1, 4, a, s, delete, pageup, etc), but as many helper keys (cmd, ctrl, alt, shift) as you would like
• Codes are case insensitive, F1 will become f1, DELETE will become delete, etc...
• If you specify a view method that does not exist, it will just call event
• If you do not want to call a view method pass an empty string as the value, i.e.
• If element type is not a focusable element, div, p, etc behavior adds tabindex attr to element
• If you set attachToDocument to true, then behavior adds listener to document instead of root view

hotkeys: {
    'ctrl:alt:o': 'open', // will fire event: 'hotkey:ctrl:alt:o', will call: this.view.open()
    'ctrl:alt:p': '' // will only fire event: 'hotkey:ctrl:alt:p', will not call any method
}
