我是Angulars的新手,我正在使用1.6.5版本。
我希望我的元素在点击时不仅仅显示淡出,而且在点击时淡出而不是仅仅是隐藏,这是我的代码HTML:
<ul>
<li class="try" ng-if="bool"><label>email</label> : taoufiq.benallah@gmail.com</li>
<li ng-click="bool=false"><label>téléphone</label> : +2126-13-85-98-34 </li>
<li ng-click="bool=true"><label>website</label> : oujda.ma.taoufiq.com</li>
</ul>
这是我的CSS文件:
.try.ng-enter {
transition: 2s all;
opacity: 1;
}
.try.ng-enter.ng-enter-active {
transition: 2s all;
opacity: 1;
}
.try.ng-leave {
transition: 2s all;
opacity : 1;
}
.try.ng-leave.ng-leave-active {
transition: 2s all;
opacity: 1;
}
我遇到的问题是我的元素不会出现在2s但是立即出现.. 感谢您的帮助。

之所以发生这种情况,是因为您使用的是ng-if
。这使您的元素完全从DOM中消失。将其更改为ng-show
,它将解决您的问题。
完整代码:
<ul>
<li class="try" ng-show="bool"><label>email</label> : taoufiq.benallah@gmail.com</li>
<li ng-click="bool=false"><label>téléphone</label> : +2126-13-85-98-34 </li>
<li ng-click="bool=true"><label>website</label> : oujda.ma.taoufiq.com</li>
</ul>

你也可以使用AngA方式的ngAnimate:
var app = angular.module('taskApp', ['ngAnimate']);
app.controller('taskCtrl', function($scope) {
$scope.tasks = [
{ title: 'Go to the Zoo'},
{ title: 'Take a Nap'},
{ title: 'Start Learning AngularJS'},
{ title: 'Meet Susan at the Gym'}
];
$scope.addtask = function() {
$scope.tasks.push($scope.task);
$scope.task = {};
};
$scope.removeItem = function(index) {
$scope.tasks.splice(index, 1);
};
});
