我有以下回调。但如果我开始，我的播放器总是会显示第二个回调。我怎样才能进行回调并随机显示两个视频?

callback('{"video": {"mp4": "http://c0026122.cdn1.cloudfiles.rackspacecloud.com/193807.mp4", "webm": "http://5860e9e4db2f4cebe1e6-cc12bb9b5e092d34d0fadb7ce5f280a3.r47.cf1.rackcdn.com/193807.webm", "title": "Touch"}}');
callback('{"video": {"mp4": "http://c0026125.cdn1.cloudfiles.rackspacecloud.com/064915.mp4", "webm": "http://a95a046574a64b9ea43b-53264ce826f5cfe73ee69a0c3c37eccc.r68.cf1.rackcdn.com/64915.webm", "title": "Grace / Fever / Dinner / Heart to Heart / Videogame"}}');
return;

如果你问的是我认为你在问的问题，并且你想显示一个随机视频，那么你可能要考虑从视频数组中生成一个随机数。

var videos = [ // Place any and all videos in this array
    {"video": {"mp4": "http://c0026122.cdn1.cloudfiles.rackspacecloud.com/193807.mp4", "webm": "http://5860e9e4db2f4cebe1e6-cc12bb9b5e092d34d0fadb7ce5f280a3.r47.cf1.rackcdn.com/193807.webm", "title": "Touch"}},
    {"video": {"mp4": "http://c0026125.cdn1.cloudfiles.rackspacecloud.com/064915.mp4", "webm": "http://a95a046574a64b9ea43b-53264ce826f5cfe73ee69a0c3c37eccc.r68.cf1.rackcdn.com/64915.webm", "title": "Grace / Fever / Dinner / Heart to Heart / Videogame"}}
];
var rand = Math.floor(Math.random() * videos.length); // Generate random number based on number of videos
callback(videos[rand]); // Run the callback with a random video
