AngularJS中的lightGallery（jQuery插件）

Question

I'm trying to get the lightGallery jQuery plugin ( http://sachinchoolur.github.io/lightGallery/index.html ) to work with AngularJS.

I found some answers that suggested I needed a directive, so I created the following:

.directive('lightGallery', function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            jQuery(element).lightGallery();
        }
    };
})

Then in my view I do this:

<ul lightGallery>
    <li ng-repeat="photo in album.photos" data-src="{{photo.fullres}}">
        <img ng-src="{{photo.thumbnail}}" />
    </li>
</ul>

(I also tried with <ul light-gallery> ) When I run the page nothing happens when I click any of the thumbnails. I can put an alert() in the link function, though, and that is displayed.

How can I get AngularJS to play along with jQuery and this plugin?

UPDATE:

After some debugging it seems that jQuery(element).lightGallery() is executed before the model is bound to the view. So the question then is how I can get a directive to be called when everything is bound and not before.

Answer 1

Call lightGallery once ng-repeat is finished rendering.
You can just modify the directive like this

.directive('lightgallery', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      if (scope.$last) {

        // ng-repeat is completed
        element.parent().lightGallery();
      }
    }
  };
});

HTML

<ul>
  <li lightgallery ng-repeat="photo in photos" data-src="{{photo.fullres}}">
    <img ng-src="{{photo.thumbnail}}" />
  </li>
</ul>

Using a combination of 2 directives allows you to specify a parent via a directive, as well as pass in options to a scoped variable, which provides the opportunity for more customization of Light Gallery. The secondary directive triggers the parent to bind (using the same idea presented in @Clr's solution)

This directive is for the parent element, and you may pass a galleryOptions scope variable which is simply passed along when binding Light Gallery:

.directive('lightGallery', function() {
    return {
        restrict: 'A',
        scope: {
            galleryOptions: '='
        },
        controller: function($scope) {

            this.initGallery = function() {
                $scope.elem.lightGallery($scope.galleryOptions);
            };

        },
        link: function(scope, element, attr) {
            scope.elem = element;
        }
    }
})

This directive is for each "item" in the Light Gallery:

.directive('lightGalleryItem', function() {
    return {
        restrict: 'A',
        require: '^lightGallery',
        link: function (scope, element, attrs, ctrl) {

            if (scope.$last) {
                ctrl.initGallery();
            }

        }
    }
})

The resulting markup (which can really be anything you'd like by specifying the selector option when initializing Light Gallery):

<ul light-gallery gallery-options="galleryOptions">
    <li ng-repeat="photo in album.photos" data-src="{{photo.fullres}}" light-gallery-item>
        <img ng-src="{{photo.thumbnail}}" />
    </li>
</ul>

Whereas options may be any valid Light Gallery options, such as:

$scope.galleryOptions = {
    selector: '.file-trigger',
    ...
};

Answer 3

without directive..

HTML

<ul id="lightgallery">
  <li ng-repeat="image in album.images" data-src="{{imagem.fullres}}">
    <img ng-src="{{image.thumbnail}}" />
  </li>
</ul>

JavaScript

// $http, Restangular whatever to return data in album.images

// unbind before..
jQuery('#lightgallery').unbind().removeData();

// $timeout after
$timeout(function () {
  jQuery('#lightgallery').lightGallery();
}, 100);

Works for me..
