angular-swipe-element

Small extension for AngularJS to add wider support of swipes and drags

Live Demo here.

Basic usage

Define module as dependency!

var app = angular.module('app', ['angular-swipe-element']);

Define the directive!

<div swipe-element="onSwipeEnd(dir, deltaX, deltaY)" 
     swipe-element-move="onSwipeMove(dir, deltaX, deltaY)" 
     swipe-element-start="onSwipeStart(dir, deltaX, deltaY)"></div>

Define the callbacks in controller!

app.controller(function($scope) {
    $scope.onSwipeStart = function(dir, deltaX, deltaY) { console.log('Started, direction: ' + dir + '. DeltaX: ' + deltaX + '; DeltaY: ' + deltaY); };
    $scope.onSwipeMove = function(dir, deltaX, deltaY) { console.log('Moved, direction: ' + dir + '. DeltaX: ' + deltaX + '; DeltaY: ' + deltaY); };
    $scope.onSwipeEnd = function(dir, deltaX, deltaY) { console.log('Released, direction: ' + dir + '. DeltaX: ' + deltaX + '; DeltaY: ' + deltaY); };
});

You are ready! Enjoy the plugin.
