我想在视频结束后显示一个 div。视频结束后会出现警报,但 div 仍然不可见。我做错了什么。 提前感谢您的帮助。
@section scripts
{
<script type="text/javascript" src="~/App/Controllers/TestController.js"></script>
}
<div ng-controller="TestController as ctrl" class="md-content" ng-cloak>
<h1>Test</h1>
<video id="myVideo" controls autoplay>
<source src="~/Videos/Test1.mp4">
</video>
<div id="test" ng-show="ui.showTest">
<h1>Test</h1>
Added this as a test to see if your controller is linked to the view
<p>{{ui.shouldSeeThis}}</p>
</div>
</div>
这是 Controller
angular.module('MyApp', ['ngMaterial', 'ngMessages'])
.controller('TestController', function ($scope, $http, $filter, $mdDialog) {
var vid;
function initializePlayer() {
vid = document.getElementById("myVideo");
vid.addEventListener('ended', videoFinish, false);
}
window.onload = initializePlayer;
$scope.ui = {
showTest: false,
//I've added this to see if your controller is linked to the view
shouldSeeThis: "Hello World"
};
function videoFinish() {
$scope.ui.showTest = true;
alert("VideoFinish");
}
});
最佳答案
看起来您需要强制摘要以反射(reflect) View 中的范围更改。发生这种情况是因为您正在使用 javascript 事件更改范围值。
在你的 Controller 中添加$timeout
:
.controller('TestController', function ($scope, $http, $filter, $mdDialog, $timeout)
在你的函数中用它包装代码:
function videoFinish() {
$timeout(function() {
$scope.ui.showTest = true;
alert("VideoFinish");
});
}
