Google Picker API：过滤 YouTube 电影

Question

您好，我一直在使用 Google Picker API (http://code.google.com/apis/picker/)。我有一个搜索 YouTube 电影的工作演示（代码如下）。

当前版本返回所有视频。我正在尝试过滤结果，因此它只会列出来自 youtube.com 的搜索结果。选择器 API 支持这一点。但我不懂 API 文档。

文档 (http://code.google.com/apis/picker/docs/reference.html) 提到“VideoSearchView.YOUTUBE”并将其描述为“适用于 VideoSearchView.setSite() 方法的字符串常量” .

我不明白如何在下面的代码中实现此过滤器。任何帮助表示赞赏。

        Displays all videos from youtube.com:
        ???

        Example query that returns non-YouTube results: "Mobile Healing Rooms: Following Jesus on Vimeo"

        var picker = new google.picker.PickerBuilder();
        picker = picker.addView(google.picker.ViewId.VIDEO_SEARCH);
        picker = picker.enableFeature(google.picker.Feature.NAV_HIDDEN);

        picker = picker.setTitle('Selecteer een YouTube video');
        picker = picker.setCallback(googlePickerCallback);
        picker = picker.build();
        picker.setVisible(true);
    }

    function googlePickerCallback(data) {
        var youTubeUrl = (data.action == google.picker.Action.PICKED) ? data.docs[0].url : '';

        if (youTubeUrl != '')
        {
            $('#block_youtube_url').val(youTubeUrl);
        }
    }

尝试以下等效方法：

// Create and render a Picker object for searching YouTube videos.
function createPicker() {
    var picker = new google.picker.PickerBuilder().
        addView(new google.picker.VideoSearchView().
            setSite(google.picker.VideoSearchView.YOUTUBE)).
        setCallback(pickerCallback).
        build();
    picker.setVisible(true);
}

如果您通过 ViewId 添加视图，您将没有机会调用特定于视图的方法。这就是为什么暴露了一些 View 派生类的原因。
