当load-video属性为displayVideo时，我正在使用名为true的指令在DOM中加载视频。
<figure id = "positionVideo" ng-show = "displayVideo">
<load-video></load-video>
</figure>
loadVideo指令：
angular.module('homePage')
.directive('loadVideo', function($document, $window) {
return {
restrict: 'E',
templateUrl: 'partials/video/video.html',
link: function(scope, element) {
element.data('loadVideo',true);
angular.element($document[0].body).on('click',function(e) {
var inElem = angular.element(e.target).inheritedData('loadVideo');
if (inElem) {
scope.displayVideo = true;
} else {
scope.displayVideo = false;
}
})
}
};
});
video.html
<video height = "50%" width = "150%" id = "playVideo" ng-click="playIt()" poster = "images/eagle.jpg" controls>
<source src = "images/lion.mp4" type = "video/mp4">
</video>
figure代码可以访问此控制器：
angular.module('homePage').controller('watchVideo', ['$scope', '$location', function($scope, $location) {
$scope.displayVideo = false;
$scope.videoAvailable = function () {
$scope.displayVideo = true;
};
$scope.closeVideo = function() {
$scope.displayVideo = false;
};
$scope.playIt = function() {
if (jQuery("#playVideo").get(0).paused) {
jQuery("#playVideo").get(0).play();
}
else {
jQuery("#playVideo").get(0).pause();
}
}
}]);
我不明白为什么在将video属性更改为displayVideo时，false元素未隐藏。
我在下面提供我的整个申请表格：
<div class="firstView" ng-controller = "watchVideo">
<figure class="logo" ng-controller = "logo" ng-click="goToUrl('/home')"> </figure>
<cite>Every brand has a story.</cite>
<h2 id = "h2Heading"> <a ng-click = "videoAvailable()">Watch the video </a></h2>
<aside> → </aside>
<figure id = "positionVideo" ng-show = "displayVideo">
<load-video></load-video>
</figure>
<summary ng-controller = "buttonViewCtrl">
<button type="button" ng-hide = "buttonDisplay" ng-show = "!displayVideo" class="btn btn-default btn-lg navButton" aria-label="Center Align" ng-click="nav()">

</button>
<button type="button" class="close" data-dismiss="alert" aria-label="Close" id = "closeButton" ng-show = "buttonDisplay" ng-hide = "!displayVideo" ng-click = "closeNav(); closeVideo()"><span aria-hidden="true">×</span> </button>
<div ng-show = "buttonDisplay" id = "buttonDisplayContent" class = "cssFade">

答案 0 :(得分：0)
视频未隐藏，因为Angular不知道模型已更改。实际上，element.on()只是普通的旧jQuery on函数，它不是Angular感知的。
你可能已经注意到，当你点击外面然后在里面时，视频会消失：那是因为ng-click处理程序首先被激活为最内层的侦听器，会触发摘要阶段，导致{{1}更新视图。
处理此问题的正确方法是ng-hide：
$scope.$apply()请参阅this fiddle。
