    Code (markup):
    I want to detect the player state and if it is zero, I want to redirect the page to another URL. How do I go about doing that?

    When the video ends, the payer state becomes 0

    There is a player state function in the above code

    
function getPlayerState() {
          if (ytplayer) {
            return ytplayer.getPlayerState();
          }
        }
    Code (markup):
    If you are good at javascript can you give me a hand here?

    All I want is the player state javascript.

    I don't need any of the other JavaScript whatsoever.

    I simply need to find a way to detect when the video has finished.
