How to play a music list?
Idea: To play a music list, you need to implement two purposes: one is loop, and the other is to determine whether the current song is played completely. The loop is performed only after the current song is played completely. This achieves detection.
VaR I = 0;
Playthis (firstmusic)
// Real-time detector, with an interval of 1 second
D = setinterval (function shwotimer ()
{
If (WMP. playstate = 1)
{
If (I> = soundarray. length)
{
// Clear the loop after the playback is complete.
Clearinterval (d );
}
Else
{
// When the playback is complete, play the next one.
Playthis (URL );
}
}
}
, 1000 );
If you need other controls, such as pause, you can set an identifier, that is, the current pause, the next step is playing, and vice versa.
VaR pauseflag = 0;
Function command_pause ()
{
If (pauseflag = 0)
{
WMP. Controls. Pause ();
}
Else
{
WMP. Controls. Play ();
}
Pauseflag = 1? ;
}
