Usage

Initialize Draggabilly as a jQuery plugin

var $draggable = $('.draggable').draggabilly({
  // options...
})

Initialize Draggabilly with vanilla JS

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

// or pass in selector string as first argument
var draggie = new Draggabilly( '.draggable', {
  // options...
});

// if you have multiple .draggable elements
// get all draggie elements
var draggableElems = document.querySelectorAll('.draggable');
// array of Draggabillies
var draggies = []
// init Draggabillies
for ( var i=0; i < draggableElems.length; i++ ) {
  var draggableElem = draggableElems[i];
  var draggie = new Draggabilly( draggableElem, {
    // options...
  });
  draggies.push( draggie );
}

Classes

.is-pointer-down added when the user's pointer (mouse, touch, pointer) first presses down.
.is-dragging added when elements starts to drag.

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

Bind events with jQuery with standard jQuery event methods .on(), .off(), and .one(). Inside jQuery event listeners this refers to the Draggabilly element.

// jQuery
function listener(/* parameters */) {
  // get Draggabilly instance
  var draggie = $(this).data('draggabilly');
  console.log( 'eventName happened', draggie.position.x, draggie.position.y );
}
// bind event listener
$draggable.on( 'eventName', listener );
// unbind event listener
$draggable.off( 'eventName', listener );
// bind event listener to trigger once. note ONE not ON
$draggable.one( 'eventName', function() {
  console.log('eventName happened just once');
});

Bind events with vanilla JS with .on(), .off(), and .once() methods. Inside vanilla JS event listeners this refers to the Draggabilly instance.

// vanilla JS
function listener(/* parameters */) {
  console.log( 'eventName happened', this.position.x, this.position.y );
}
// bind event listener
draggie.on( 'eventName', listener );
// unbind event listener
draggie.off( 'eventName', listener );
// bind event listener to trigger once. note ONCE not ONE or ON
draggie.once( 'eventName', function() {
  console.log('eventName happened just once');
});

dragStart

Triggered when dragging starts and the element starts moving. Dragging starts after the user's pointer has moved a couple pixels to allow for clicks.

// jQuery
$draggable.on( 'dragStart', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'dragStart', function( event, pointer ) {...})

event - Type: Event - the original mousedown or touchstart event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

dragMove

Triggered when dragging moves.

// jQuery
$draggable.on( 'dragMove', function( event, pointer, moveVector ) {...})
// vanilla JS
draggie.on( 'dragMove', function( event, pointer, moveVector ) {...})

event - Type: Event - the original mousemove or touchmove event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY
moveVector Type: Object - How far the pointer has moved from its start position { x: 20, y: -30 }

dragEnd

Triggered when dragging ends.

// jQuery
$draggable.on( 'dragEnd', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'dragEnd', function( event, pointer ) {...})

event - Type: Event - the original mouseup or touchend event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

pointerDown

Triggered when the user's pointer (mouse, touch, pointer) presses down.

// jQuery
$draggable.on( 'pointerDown', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'pointerDown', function( event, pointer ) {...})

event - Type: Event - the original mousedown or touchstart event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

pointerMove

Triggered when the user's pointer moves.

// jQuery
$draggable.on( 'pointerMove', function( event, pointer, moveVector ) {...})
// vanilla JS
draggie.on( 'pointerMove', function( event, pointer, moveVector ) {...})

event - Type: Event - the original mousemove or touchmove event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY
moveVector Type: Object - How far the pointer has moved from its start position { x: 20, y: -30 }

pointerUp

Triggered when the user's pointer unpresses.

// jQuery
$draggable.on( 'pointerUp', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'pointerUp', function( event, pointer ) {...})

event - Type: Event - the original mouseup or touchend event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

staticClick

Triggered when the user's pointer is pressed and unpressed and has not moved enough to start dragging.

click events are hard to detect with draggable UI, as they are triggered whenever a user drags. Draggabilly's staticClick event resolves this, as it is triggered when the user has not dragged.

// jQuery
$draggable.on( 'staticClick', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'staticClick', function( event, pointer ) {...})

event - Type: Event - the original mouseup or touchend event
pointer - Type: MouseEvent or Touch - the event object that has .pageX and .pageY

Methods

disable

// jQuery
$draggable.draggabilly('disable')
// vanilla JS
draggie.disable()

enable

// jQuery
$draggable.draggabilly('enable')
// vanilla JS
draggie.enable()

setPosition

// jQuery
$draggable.draggabilly( 'setPosition', x, y )
// vanilla JS
draggie.setPosition( x, y )

x - Type: Number - horizontal position
y - Type: Number - vertical position

destroy

// jQuery
$draggable.draggabilly('destroy')
// vanilla JS
draggie.destroy()

jQuery.fn.data('draggabilly')

Get the Draggabilly instance from a jQuery object. Draggabilly instances are useful to access Draggabilly properties.

var draggie = $('.draggable').data('draggabilly')
// access Draggabilly properties
console.log( 'draggie at ' + draggie.position.x + ', ' + draggie.position.y )

Properties

position

draggie.position
// => { x: 20, y: -30 }

position - Type: Object
x - Type: Number
y - Type: Number

Module loaders

Webpack & Browserify

Install Draggabilly with npm.

npm install draggabilly

var Draggabilly = require('draggabilly');

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

To use Draggabilly as a jQuery plugin, you need to install and call jQuery Bridget.

npm install jquery-bridget

var $ = require('jquery');
var jQueryBridget = require('jquery-bridget');
var Draggabilly = require('draggabilly');

// make Draggabilly a jQuery plugin
jQueryBridget( 'draggabilly', Draggabilly, $ );
// now you can use $().draggabilly()
$('.draggable').draggabilly({...})

RequireJS

Draggabilly works with RequireJS.

You can require draggabilly.pkgd.js..

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

To use Draggabilly as a jQuery plugin with RequireJS and draggabilly.pkgd.js, you need to call jQuery Bridget.

// require the require function
requirejs( [ 'require', 'jquery', 'path/to/draggabilly.pkgd.js' ],
  function( require, $, Draggabilly ) {
    // require jquery-bridget, it's included in draggabilly.pkgd.js
    require( [ 'jquery-bridget/jquery-bridget' ],
    function( jQueryBridget ) {
      // make Draggabilly a jQuery plugin
      jQueryBridget( 'draggabilly', Draggabilly, $ );
      // now you can use $().draggabilly()
      $('.draggable').draggabilly({...})
    }
  );
});

Or, you can manage dependencies with a package manager like npm or Bower. Set baseUrl to the package directory and set a path config for all your application code.

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

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

To use Draggabilly as a jQuery plugin with a package manager, you need install and to call jQuery Bridget.

requirejs.config({
  baseUrl: 'node_modules/',
  paths: {
    jquery: 'jquery/dist/jquery'
  }
});

requirejs( [
    'jquery',
    'draggabilly/draggabilly',
    'jquery-bridget/jquery-bridget'
  ],
  function( $, Draggabilly, jQueryBridget ) {
    // make Draggabilly a jQuery plugin
    jQueryBridget( 'draggabilly', Draggabilly, $ );
    // now you can use $().draggabilly()
    $('.draggable').draggabilly({...})
});
