How to use hammer.js with Angular.js

问题

I'm new with Angular.js and reading i know angular dont have events like tap, double tap, etc. I'm trying to combine with Hammer.js without success.

Code from gist

/**
 * angular-hammer.js
 * Inspired by AngularJS' implementation of "click dblclick mousedown..." 
 *
 * This ties in the Hammer events to attributes like:
 * 
 *   hm-tap="add_something()"
 *   hm-swipe="remove_something()"
 *
 * and also has support for Hammer options with:
 *
 *  hm-tap-opts="{hold: false}"
 *
 * or any other of the "hm-event" listed underneath.
 */
angular.forEach('hmTap:tap hmDoubletap:doubletap hmHold:hold hmTransformstart:transformstart hmTransform:transform hmTransforend:transformend hmDragstart:dragstart hmDrag:drag hmDragend:dragend hmSwipe:swipe hmRelease:release'.split(' '), function(name) {
  var directive = name.split(':');
  var directiveName = directive[0];
  var eventName = directive[1];
  angular.module('MYMODULE').directive(directiveName, 
  ['$parse', function($parse) {
    return function(scope, element, attr) {
      var fn = $parse(attr[directiveName]);
      var opts = $parse(attr[directiveName + 'Opts'])(scope, {});
      element.hammer(opts).bind(eventName, function(event) {
        scope.$apply(function() {
          console.log("Doing stuff", event);
          fn(scope, {$event: event});
        });
      });
    };
  }]);
});

now i've added to my html file

<!--...-->
<script src="/js/jquery-1.9.0.js"></script>
    <script src="/js/angular.js"></script>

    <script src="/js/hammer.js"></script>
    <script src="/js/jquery.hammer.js"></script>
    <script src="/js/angular-hammer.js"></script>

    <script src="/js/app/controllers.js"></script>
</html>

But when i try to use in my html it doesn't work.

I've tried with

<li hmTap="click($event)">...</li>
<li ngTap="click($event)">...</li>
<li hm-tap="click($event)">...</li>
<li ng-tap="click($event)">...</li>

no one works, can help me with this trouble?

Give this a go.

Add hammer.js and jquery.hammer.js to your solution. With JQuery and Angular.

Something like this:

<script src="js/jquery/jquery.min.js"></script>
<script src="js/hammer/hammer.js"></script>
<script src="js/hammer/jquery.hammer.js"></script>
<script src="js/angular/angular.min.js"></script>

Then use Angular directives to define new HTML attributes.

In this example I am creating a new attribute called on-tap

angular.module('myApp.directives', [])
       .directive('onTap', function () {
         return function (scope, element, attrs) {
           return $(element).hammer({
             prevent_default: false,
             drag_vertical: false
           })
             .bind("tap", function (ev) {
               return scope.$apply(attrs['onTap']);
             });
         };
       });

You can then create a directive per Hammer event:

hold, tap, doubletap, transformstart, transform, transformend, dragstart, drag, dragend, release, swipe.

Your HTML would then look like this:

<button on-tap="DoAngularMethod()">Tap me</button>

Here is exactly what are you looking for:
https://github.com/wzr1337/angular-gestures

this new libary allows you to implement all of gestures you need.

Hope you find it interesting. :)

There are some hammer directive implementations for Angular you could try to use:

https://github.com/randallb/angular-hammer

https://github.com/dreame4/angular-hammer

I used randallb lib and i added

'hmPan:pan',
'hmPanLeft:panleft',
'hmPanRight:panright',

in the hmGestures array, so i can use pan too!
