Adding KeyListener to HTML5/LimeJS Game

Hey guys,

I've recently watched the workshop "Coding Your First HTML5 Game". I've decided to extend the project a little. Now I've tried to add some Keyevent Listeners but it doesn't work for me. I hope someone may help me.

This is my markup:

goog.events.listen(goog.global, ['keydown', 'keyup'], function(e) {
        switch (e.keyCode) {
            case 37: //LEFT
                this.frog.startMovement(WEST);
                break;
            case 65: //A
                this.frog.startMovement(WEST);
                break;
            case 38: //UP
                this.frog.startMovement(NORTH);
                break;
            case 87: //W
                this.frog.startMovement(NORTH);
                break;          
            case 39: //Right
                this.frog.startMovement(EAST);
                break;
            case 68: //D
                this.frog.startMovement(EAST);
                break;
            case 40: //Down
                this.frog.startMovement(SOUTH);
                break;
            case 83: //S
                this.frog.startMovement(SOUTH);
                break;
        }
    });

I've also tried to do something like "this.startMovement(EAST);" and the code above is out of a forum.

Thanks for helping me!

I fixed it on my own. It was like: 

goog.events.listen(goog.global, ['keydown', 'keyup'], function(e) {
        switch (e.keyCode) {
            case 37: //LEFT
                console.log("Left arrow pressed");
                this.startMovement(WEST);
                break;
...
    }
}, null, this.frog);
