Alternating Multiple Video Lists In Html5 Stored As Javascript Arrays

I have designed an i-phone-like screen on a web browser where I am testing this application I am in the process of building. It works great up until the point where I want to call

Solution 1:

make Vids like this:

var Vids = function(vidArray=[]) {
var _currentId = -1;
var _urls = vidArray;
return {
    next: function() {
        if (++_currentId >= _urls.length)
            _currentId = 0;
         return this.play(_currentId);
    },
    prev: function() {
        if (--_currentId < 0)
            _currentId = _urls.length - 1;
        return this.play(_currentId);
    },
    play: function(id) {
        var myVideo = document.getElementsByTagName('video')[0];
        myVideo.src = _urls[id];
        myVideo.load();
        myVideo.play();
        return false;
   }
}
};

then prepare your url array and call Vids:

var urls =["videos/ParisisBurning_370x660_Get_Into_The_Suits_Vert.mp4","videos/ParisisBurning_370x660_School_Vert.mp4","videos/ParisisBurning_660x370_I_came_I_saw_Vert.mp4", "videos/ParisisBurning_660x370_I_went_to_a_ball.mp4"];
Vids(urlf).play(3); //Replace 3 with any id
