Make that shiz draggable

draggabilly.desandro.com

Rad because it supports IE8+ and multi-touch.

Grab a packaged source file:

• draggabilly.pkgd.min.js for production
• draggabilly.pkgd.js for development

Or if you're cool with the command line, install with Bower.

bower install draggabilly

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

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

Type: String

Values: 'x' or 'y'

axis: 'x'

Constrains movement to horizontal or vertical axis.

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.

Type: Array

Values: [ x, y ]

grid: [ 20, 20 ]

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

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.

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');
});

.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

.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

.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

draggie.disable()

draggie.enable()

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( ... );
});
