如何阅读 Javascript 配置模式？

Question

如果我想在这段代码中创建提醒标题名称的函数，如何在不将 jwplayer 库包含到我的 HTML 文件的情况下编写提醒它的函数？

http://jsfiddle.net/fs7p0ec4/1/

jwplayer( "my_media_player" ).setup({
 image: "http://example.com/poster.jpg",
 title: "testHLS",
 rtmp: { bufferlength: "2" },
 bufferlength: "2",
 width: "100%",
 aspectratio : "16:9",
 playlist: [{sources: [ { file: "http://example.com/playlist.m3u8" } ]}],
primary: "flash",
repeat: true,
controlbar: true,
stretching: "exactfit"
});

var jwplayerClass = function(xx){ }
jwplayerClass.prototype.setup = function(info) {
   var XWP = info.playlist[0].sources[0].file; 
   alert(XWP); return this 
};
var jwplayer = function (xx) { 
    return new jwplayerClass(xx); 
};
