在呈现HTML后初始化时,iFrame不加载src

标签: javascript html angularjs iframe youtube-api

所以我有一个页面,我需要在iFrame中嵌入一个youtube预告片,根据视图中点击的电影/系列。为此,我使用Youtube Search API。

现在加载页面时,它首先从另一个API获取一些数据,加载Youtube API,然后获取预告片的videoId,并将其分配给视图中的$scope变量。 / p>

在视图中我得到了一些代码:

<div class="row">
    <iframe width="420" height="315" ng-src="{{video}}" frameborder="0" allowfullscreen></iframe>
</div>

控制器看起来像这样:

var serieId = $routeParams.id;

    $http.get("http://api.tvmaze.com/shows/" + serieId)
        .success(function (data) {
            console.log(data);
            $scope.name = data.name;
            $scope.img = data.image.medium;
            $scope.rating = data.rating;
            initYTAPI();
            $http.get("http://api.tvmaze.com/shows/" + serieId + "/episodes")
                .success(function (episodes) {
                    console.log(episodes);
                    $scope.episodes = episodes;
                    var maxSeason = 0;
                    for (var i = 0; i < episodes.length; i++) {
                        if (episodes[i].season > maxSeason) {
                            maxSeason = episodes[i].season
                        }
                    }

                    $scope.seasonCount = [];
                    for (var i = 1; i <= maxSeason; i++) {
                        $scope.seasonCount.push(i)
                    }
                });
        });

initYTAPI函数:

    gapi.client.setApiKey("MY_API_KEY");
    gapi.client.load("youtube", "v3", function(){
        //yt api is ready
        console.log("Api ready");
        var query = $scope.name + " Official Trailer";
        var request = gapi.client.youtube.search.list({
            part: "snippet",
            type: "video",
            q: query,
            maxResults: 1
        });
       request.execute(function(response){
            var base_URL = "https://www.youtube.com/embed/";
            var url = base_URL + response.items[0].id.videoId;
            url = $sce.trustAs($sce.RESOURCE_URL, url);
            console.log(url);
            $scope.video = url;

            //Tried to do it with ng-bing-html aswell
            //$scope.trailerHtml = "<iframe width=\"420\" height=\"315\" ng-src=\"url\" frameborder=\"0\" allowfullscreen></iframe>";
        });
    });

我已经使用开发人员模式检查了该页面,看看iFrame是否正确加载,但它似乎不包含任何src(或ng-src)属性。< / p>

我认为它与javascript执行之前的视图渲染有关,但我已经尝试制作一个服务,其中url已经预先计算好,并从那里获取url,但似乎没有帮助。

所有帮助将不胜感激!

您的范围变量($ scope.video)将在Angular的事件循环之外执行。您可以在$ scope.video(BAD)上设置监视,或者在$ scope中包装自定义范围更改。$ apply():

       request.execute(function(response){
        var base_URL = "https://www.youtube.com/embed/";
        var url = base_URL + response.items[0].id.videoId;
        url = $sce.trustAs($sce.RESOURCE_URL, url);
        console.log(url);
        $scope.$apply(function(){
          $scope.video = url;
        });
