我想有一种滑块(但实际上更像是一个ppt,根据你点击按钮你会得到的结果会有所不同)。
我有效地使用ng-animate-swap来改变当前显示的幻灯片,并且只在一种方式下才能正常工作。 我的问题是当我尝试走另一条路时,我改变了我的动画类,但对于即将上映的幻灯片,动画仍将是之前的状态之一... 你可以在这里找到一个受ng-animate-swap doc启发的工作示例: http://plnkr.co/edit/dArF1W7eM7Znur7Myx3O?p=preview
正如您所看到的,问题是CSS类的更改仅适用于新幻灯片,而不适用于将要删除的幻灯片。
您可以在下面找到相关代码:
index.html:
<body ng-app="ngAnimateSwapExample">
<div ng-controller="AppCtrl">
<div class="container">
<div ng-animate-swap="number" class="cell {{swapAnimation}}" ng-class="colorClass(number)">
{{ number }}
</div>
</div>
<a ng-click="previousNumber()">PREVIOUS</a>
<a ng-click="nextNumber()">NEXT</a>
</div>
</body>
script.js:
.controller('AppCtrl', ['$scope',function($scope) {
$scope.number = 0;
var colors = ['red','blue','green','yellow','orange'];
$scope.colorClass = function(number) {
return colors[number % colors.length];
};
$scope.nextNumber = function(){
$scope.swapAnimation = "swap-animation";
$scope.number += 1;
};
$scope.previousNumber = function(){
$scope.swapAnimation = "swap-animation-reverse";
$scope.number -= 1;
};
}]);
animations.css:
.container {
height:250px;
width:250px;
position:relative;
overflow:hidden;
border:2px solid black;
}
.container .cell {
font-size:150px;
text-align:center;
line-height:250px;
position:absolute;
top:0;
left:0;
right:0;
border-bottom:2px solid black;
}
.swap-animation.ng-enter, .swap-animation.ng-leave {
transition:0.5s linear all;
}
.swap-animation.ng-enter {
top:-250px;
}
.swap-animation.ng-enter-active {
top:0px;
}
.swap-animation.ng-leave {
top:0px;
}
.swap-animation.ng-leave-active {
top:250px;
}
.swap-animation-reverse.ng-enter, .swap-animation-reverse.ng-leave {
transition:0.5s linear all;
}
.swap-animation-reverse.ng-enter {
top:250px;
}
.swap-animation-reverse.ng-enter-active {
top:0px;
}
.swap-animation-reverse.ng-leave {
top:0px;
}
.swap-animation-reverse.ng-leave-active {
top:-250px;
}

只需在nextNumber()和previousNumber()逻辑中更改cssClass后添加超时,因此在第一个循环中元素更改类,在下一个循环中,ng-animate-swap执行动画。
$scope.nextNumber = function(){
$scope.swapAnimation = "swap-animation";
$timeout(function(){
$scope.number += 1;
});
};
$scope.previousNumber = function(){
$scope.swapAnimation = "swap-animation-reverse";
$timeout(function(){
$scope.number -= 1;
});
};
