Question

我试图隐藏手柄（允许你拖动的滑块和滑块。

I'm currently using the nouislider javascript library现在正试图摆脱它。

到目前为止，我已尝试过以下方法：

Html: 
<div class = 'slider' id='sliderinfo'> </div>
Javascript:
var slider = document.getElementById('sliderinfo');
var hider = slider.getElementsByClassName('.noUi-handle');
hider.remove();
//Separate way of hding

以及以下有些相关的SO response包括these two，而且我对隐藏或删除滑块的句柄没有任何回应。

感谢。

我通过查看之前接受的答案的底部找到答案，虽然我不清楚。

public class MainActivity extends AppCompatActivity {

    private Button btn;
    private boolean playPause;
    private MediaPlayer mediaPlayer;
    private ProgressDialog progressDialog;
    private boolean initialStage = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn = (Button) findViewById(R.id.audioStreamBtn);
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        progressDialog = new ProgressDialog(this);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (!playPause) {
                    btn.setText("Pause Streaming");

                    if (initialStage) {
                        new Player().execute("https://www.radioking.com/widgets/player/player.php?id=480&c=%23f39c12&ii=&p=1&pp=1&i=1&eq=1&po=1&t=1&a=1&f=big");
                    } else {
                        if (!mediaPlayer.isPlaying())
                            mediaPlayer.start();
                    }

                    playPause = true;

                } else {
                    btn.setText("Launch Streaming");

                    if (mediaPlayer.isPlaying()) {
                        mediaPlayer.pause();
                    }

                    playPause = false;
                }
            }
        });
    }

    @Override
    protected void onPause() {
        super.onPause();

        if (mediaPlayer != null) {
            mediaPlayer.reset();
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }

    class Player extends AsyncTask<String, Void, Boolean> {
        @Override
        protected Boolean doInBackground(String... strings) {
            Boolean prepared = false;

            try {
                mediaPlayer.setDataSource(strings[0]);
                mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mediaPlayer) {
                        initialStage = true;
                        playPause = false;
                        btn.setText("Launch Streaming");
                        mediaPlayer.stop();
                        mediaPlayer.reset();
                    }
                });

                mediaPlayer.prepare();
                prepared = true;

            } catch (Exception e) {
                Log.e("MyAudioStreamingApp", e.getMessage());
                prepared = false;
            }

            return prepared;
        }

        @Override
        protected void onPostExecute(Boolean aBoolean) {
            super.onPostExecute(aBoolean);

            if (progressDialog.isShowing()) {
                progressDialog.cancel();
            }

            mediaPlayer.start();
            initialStage = false;
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            progressDialog.setMessage("Buffering...");
            progressDialog.show();
        }
    }
}
