有沒有辦法停止由$ animate.addClass啓動的動畫?
angular.module("app", []);
angular.module("app").directive("stopAnimation", function($animate) {
return {
link: function(scope, element) {
setTimeout(function() {
// Start animation
scope.$applyAsync(function() {
var promise = $animate.addClass(element, "is-visible");
// Stop animation
setTimeout(function() {
$animate.cancel(promise);
}, 100);
});
});
}
};
});
.header {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 60px;
background: red;
transform: translateY(-100%);
}
.header.is-visible {
transform: translateY(0);
}
.header.is-visible {
transition: transform 3s;
}

在這個演示動畫應該爲100ms後停止,因爲承諾被取消。然而,它正常結束。我想要實現的是停止動畫,並立即跳轉到最終狀態。
