我想在使用ng-repeat重复的自定义指令上使用ngAnimate。 如果我在一个简单的html列表项上使用ng-repeat,动画效果会很好。但是,只要通过自定义指令元素替换list-item,就不会触发动画。
我错过了什么/做错了什么?
代码(Plunker Demo):
HTML
<h3>Simple ng-repeat</h3>
<ul>
<li class="animate-repeat" ng-repeat="val in testValues">{{ val }}</li>
</ul>
<h3>ng-repeat on custom directive</h3>
<ul >
<animation-test class="animate-repeat" ng-repeat="val in testValues" test-val="val"></animation-test>
</ul>
Javascript
var app = angular.module('application', ['ngAnimate']);
app.controller('mainController', [ '$scope', mainController]);
function mainController($scope){
// just for demo purposes
$scope.testValues = [];
$scope.addItem = function(){
var len = $scope.testValues.length;
$scope.testValues.unshift('Value #' + len);
};
$scope.removeItem = function(){
$scope.testValues.pop();
};
}
app.directive('animationTest', animationTest);
function animationTest(){
return {
template: ' <li> {{testVal}} </li> ',
scope: {
testVal: '<'
}
};
}
CSS(使用animate.css)
.animate-repeat.ng-enter {
animation: 0.5s slideInUp;
}
.animate-repeat.ng-leave,
.animate-repeat.ng-move {
animation: 0.5s slideOutDown;
}
@-webkit-keyframes slideInUp {
from {
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
visibility: visible;
}
to {
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
}
@keyframes slideInUp {
from {
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
visibility: visible;
}
to {
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
}
.slideInUp {
-webkit-animation-name: slideInUp;
animation-name: slideInUp;
}
@-webkit-keyframes slideOutDown {
from {
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
to {
visibility: hidden;
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
}
}
@keyframes slideOutDown {
from {
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
to {
visibility: hidden;
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
}
}
.slideOutDown {
-webkit-animation-name: slideOutDown;
animation-name: slideOutDown;
}

您可以简单地将指令绑定到<li>
元素,然后使您的确切代码正常工作。所以只需将指令的HTML更改为:
<li animation-test class="animate-repeat" ng-repeat="val in testValues" test-val="val"></li>
你的指示是:</ p>
app.directive('animationTest', animationTest);
function animationTest(){
return {
template: '{{testVal}}',
scope: {
testVal: '<'
}
};
}
或者如果你想按自己的方式去做,你需要为指令元素添加一个类,即。 directive-block
然后将动画设置为指令元素本身,如下所示:
HTML:
<animation-test class="directive-block" ng-repeat="val in testValues" test-val="val"></animation-test>
CSS:
.directive-block {
display: block;
animation: 0.5s slideInUp;
}
.directive-block.ng-leave-active {
animation: 0.5s slideOutDown;
}

您可以使用replace
属性:
app.directive('animationTest', animationTest);
function animationTest(){
return {
template: ' <li> {{testVal}} </li> ',
replace: true,
scope: {
testVal: '<'
}
};
}
或添加css:
.animate-repeat {
display:block;
}
