我正在构建一个包含许多幻灯片的应用程序,并且我正在使用 Angular JS 来切换触发 CSS 动画的元素上的类。我遇到的问题是,当单击一个按钮触发角度控制器上的一个函数时,该函数会更新确定元素类的 $scope 属性,导致动画开始的属性似乎在元素旧之前更新类被删除,并分配了新的类,所以元素总是只向一个方向移动。
我想要发生的是当从slide1调用proceed()函数时,让slide2从右向左滑入,它可以正确执行,但是当通过单击幻灯片2上的“后退”按钮调用backToOne函数时, slide2 应该向右滑出。
实际发生的是,当调用 backToOne() 函数时,slide2 滑到左侧。任何帮助表示赞赏。我对角度很陌生,所以我试图弄清楚我需要做什么来更新该类,然后更改导致动画发生的属性值。
提前致谢。
这是(简化的)视图:
<div ng-init="switcher='one'">
<div ng-switch="switcher" class="my-switch-container">
<div ng-switch-when="one" id="slide1" ng-class="slide1">
<p>stuff</p>
<button type="button" class="btn btn-primary" ng-click="proceed()">Proceed</button>
</div>
<div ng-switch-when="two" id=slide2" ng-class="slide2">
<p>more stuff</p>
<button type="button" class="btn" ng-click="backToOne()">Back</button>
<button type="button" class="btn btn-primary" ng-click="keepGoing()">Go</button>
</div>
<div ng-switch-when="three" id=slide3" ng-class="slide3">
<p>last stuff</p>
</div>
</div>
</div>
这是(同样,简化的)控制器:
myApp.controller('siteCtrl', ['$scope', '$http', 'SomeData', function($scope, $http, SomeData) {
$scope.model = SomeData;
$scope.animateLeft = "my-switch-animation-left";
$scope.animateRight = "my-switch-animation-right";
$scope.slide1 = $scope.animateLeft;
$scope.slide2 = $scope.animateLeft;
$scope.slide3 = $scope.animateLeft;
$scope.proceed = function() {
$scope.switcher = "two";
$scope.slide1 = $scope.animateRight;
}
$scope.backToOne = function() {
$scope.slide2 = $scope.animateRight;
$scope.switcher = "one";
}
$scope.keepGoing = function() {
$scope.switcher = "three";
$scope.slide2 = $scope.animateRight;
}
}]);
这是CSS:
.my-switch-container{
position: relative;
}
.my-switch-animation-left, .my-switch-animation-right {
width: 700px;
background-color: #FFF;
border-radius: 20px;
border: 1px solid #000;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
-webkit-box-shadow: 0 5px 15px #000;
-moz-box-shadow: 0 5px 15px #000;
-ms-box-shadow: 0 5px 15px #000;
box-shadow: 0 5px 15px #000;
margin: 0 auto;
}
.my-switch-animation-left.ng-enter,
.my-switch-animation-left.ng-leave,
.my-switch-animation-right.ng-enter,
.my-switch-animation-right.ng-leave {
-webkit-transition: 1s linear all;
-moz-transition: 1s linear all;
-o-transition: 1s linear all;
-transition: 1s linear all;
position: relative;
top: 0px;
}
/* moving right to left */
.my-switch-animation-left.ng-enter{
left: 100%;
}
.my-switch-animation-left.ng-leave,
.my-switch-animation-left.ng-enter.ng-enter-active{
left: 0;
}
.my-switch-animation-left.ng-leave.ng-leave-active{
left: -100%;
}
/* moving left to right */
.my-switch-animation-right.ng-enter{
right: 100%;
}
.my-switch-animation-right.ng-leave,
.my-switch-animation-right.ng-enter.ng-enter-active{
right: 0;
}
.my-switch-animation-right.ng-leave.ng-leave-active{
right: -100%;
}
