VideoJs TextTracks提示为空 [英] VideoJs TextTracks Cues empty

问题描述

我有以下代码：

  videojs（example_video_1，{}，function（）{
 //播放器（this）被初始化并准备就绪
 var aTextTrack = this .textTracks（）[0]; 
 
 aTextTrack.show（）; 
 var theArray = this.textTracks（）[0] ['$']; 
 console.log （theArray）; 
 console.dir（this.textTracks（）[0] ['$']）; 
 //例子：开始播放视频。
 this.play（）; 
 
}）; 
  

var theArray打印为空，但是console.dir打印数组的内容。我如何获得这些值？我知道它与javascript asyc变量有关。

干杯

这是正确的答案。它花了我一段时间来破解它，因为videoJS上没有太多文档

  videojs（example_video_1，{}，function （）{
 // Player（this）被初始化并准备就绪。
 var aTextTrack = this.textTracks（）[0]; 
 aTextTrack.on（'loaded'，function（）{ 
 console.log（'here is'）; 
 cues = aTextTrack.cues（）; 
 console.log（'Ready State'，aTextTrack.readyState（））
 console.log（'cues'，cues）; 
}）; 
 
 aTextTrack.show（）; //此方法调用触发字幕加载和加载触发
 this.play（）; 
 
}）; 
  

I need to be able to get the Cues array from TextTracks object in VideoJs.

I have the following code:

videojs("example_video_1", {}, function(){
   // Player (this) is initialized and ready.
    var aTextTrack =  this.textTracks()[0];

    aTextTrack.show();
    var theArray = this.textTracks()[0]['$'];
    console.log(theArray);
    console.dir(this.textTracks()[0]['$']);
    // EXAMPLE: Start playing the video.
    this.play();

}); 

The var theArray prints as empty but console.dir prints the contents of the Array. How can I get these values? I know its related with javascript asyc variables.

Cheers

解决方案

This is the right answer. It took me a while to hack it as there is not much documentation on videoJS

videojs("example_video_1", {}, function(){
    // Player (this) is initialized and ready.
    var aTextTrack =  this.textTracks()[0];
    aTextTrack.on('loaded', function() {
            console.log('here it is');
            cues = aTextTrack.cues();
            console.log('Ready State', aTextTrack.readyState()) 
            console.log('Cues', cues);
    });

    aTextTrack.show();//this method call triggers the subtitles to be loaded and loaded trigger
    this.play();

});
