【问题描述】:
我有一个使用$compile 将一些HTML 附加到DOM 的服务。该 HTML 包含一个 ng-show,带有用于显示和隐藏的转换,它以一个虚假条件开头。问题是当它附加到 DOM 时,它会显示隐藏转换。我怎样才能避免它?我注意到我的控制器在 $timeout 内调用此服务,然后才发生不希望的转换。

angular
.module('app', ['ngAnimate'])
.directive('compileNgShowAnimation', ($timeout, $compile) => ({
restrict: 'E',
link: (scope, element) => {
$timeout(() => {
angular
.element(element)
.append($compile(`
<div>
Show:
<input type="checkbox" ng-model="checked" aria-label="Toggle ngShow">
<br />
<div

I should show up only when the checkbox is checked.

/*transform: translate3d(0,-100%, 0);*/
opacity: 0;

/*transform: translate3d(0,0, 0);*/
opacity: 1;

transition: all linear 0.5s;

你想达到什么目的?如果我加载页面,复选框是否可见?如果你只是设置 scope.checked = true;它将是可见的,并且不会播放虚假动画
