I'm struggling to add animation effects to specific buttons and I can't seem to get the isolate scope to work properly. Check out this fiddle for reference:
Fiddle https://jsfiddle.net/gLhveeor/4/
The issue is that the mouseenter event is triggering the animation for all ng-repeat items instead of just the specific one.
Your assistance with this matter would be greatly appreciated.
It's not about a scope problem, the issue lies in initializing the TimelineLite object with an HTMLCollection of elements and then animating all of them. It would be better to select the necessary element on mouseover as shown below:
.controller('myCtrl', function ($timeout, $scope) {
$timeout(function () {
var tl = new TimelineLite();
tl.stop();
$scope.play = function ($event) {
var target = $event.target.querySelector('.foo-2');
tl.to(target, 0.4, {x: 30});
tl.play();
};
}, 0);
});
In your HTML code, make sure to pass the event object into the handler like this:
<div my-directive class="foo" ng-mouseenter="play($event)">
Check out the demo here: https://jsfiddle.net/gLhveeor/5/
One advice I can offer is to consider moving this logic into a directive instead of keeping it in the controller.
When utilizing ng-repeat, ensure that you are not assigning the same class (foo-2) to multiple elements. This can result in unexpected behavior when trying to select elements using
angular.element(document.getElementsByClassName('foo-2'));If the TimelineLite object is capable of initializing itself on multiple elements simultaneously, be cautious when referencing those elements. For example, in the code snippet:
tl.to($a1, 0.4, {x: 30});
The variable $a1 may contain both matched elements, resulting in t1 representing a collection of both elements. Therefore, calling t1.play() will impact both elements at once.
