draggabilly-rails

This is a bundled version of the draggabilly library.

Install

In your Gemfile, add:

gem 'draggabilly-rails'

Add it to your JavaScript manifest file:

//= require draggabilly.pkgd

Usage

var elem = document.querySelector('#draggable');
var draggie = new Draggabilly( elem, {
  // options...
});

When dragging, Draggabillly will add the class .is-dragging to the element.

Options

axis

Type: String

Values: 'x' or 'y'

axis: 'x'

Constrains movement to horizontal or vertical axis.

containment

Type: Element, Selector String, or Boolean

containment: '#container'

Contains movement to the bounds of the element. If true, the container will be the parent element.

grid

Type: Array

Values: [ x, y ]

grid: [ 20, 20 ]

Snaps the element to a grid, every x and y pixels.

handle

Type: Selector String

handle: '.handle'

Specifies on what element the drag interaction starts.

handle is useful for when you do not want all inner elements to be used for dragging, like inputs and forms. See back handle example on CodePen.

Events

Draggabilly is an Event Emitter. You can bind event listeners to events.

var draggie = new Draggabilly( elem );

function onDragMove( instance, event, pointer ) {
  console.log( 'dragMove on ' + event.type +
    pointer.pageX + ', ' + pointer.pageY +
    ' position at ' + instance.position.x + ', ' + instance.position.y );
}
// bind event listener
draggie.on( 'dragMove', onDragMove );
// un-bind event listener
draggie.off( 'dragMove', onDragMove );
// return true to trigger an event listener just once
draggie.once( 'dragMove', function() {
  console.log('Draggabilly did move, just once');
});

dragStart

.on( 'dragStart', function( draggieInstance, event, pointer ) { //...
  • draggieInstance - Type: Draggabilly - the Draggabilly instance
  • event - Type: Event - the original mousedown or touchstart event
  • pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

dragMove

.on( 'dragMove', function( draggieInstance, event, pointer ) { //...
  • draggieInstance - Type: Draggabilly - the Draggabilly instance
  • event - Type: Event - the original mousemove or touchmove event
  • pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

dragEnd

.on( 'dragEnd', function( draggieInstance, event, pointer ) { //...
  • draggieInstance - Type: Draggabilly - the Draggabilly instance
  • event - Type: Event - the original mouseup or touchend event
  • pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

RequireJS

Draggabilly works with RequireJS.

You can require draggabilly.pkgd.js.

requirejs( [
  'path/to/draggabilly.pkgd.js',
], function( Draggabilly ) {
  new Draggabilly( ... );
});

Or, you can manage dependencies with Bower. Set baseUrl to bower_components and set a path config for all your application code.

requirejs.config({
  baseUrl: 'bower_components/',
  paths: { // path your your app
    app: '../'
  }
});

requirejs( [
  'draggabilly/draggabilly',
  'app/my-component.js'
], function( Draggabilly, myComp ) {
  new Draggabilly( ... );
});
