Discover multiple jwplayers on a page

问题

I need to write some javascript code which will loop through all jwplayers available on a page.

The jwplayer api has a function selectPlayer():

var player = jwplayer.api.selectPlayer();

But this only returns the first player on the page. I can't see a way to find them all?

回答1:

There are a few ways to do this, but the simplest would be to call "jwplayer(x)" - where x is a zero-based index relating to an Array of jwplayers on the page - as this will return the Player instance at that index.

So for JW7 / JW8 you could simply do the following:

var jwpAll = document.querySelectorAll('.jwplayer');
for(var jwpIndex=0,jwpTotal=jwpAll.length;jwpIndex<jwpTotal;jwpIndex++){
    var player = jwplayer(jwpIndex);
}
