Javascript function variables issue

Question

What is the problem with my script? When I execute it, the alert (line 2) gives me "100,200,300undefinedundefined", so is seems like 100,200,300 is interpreted as h1 when I would like it to be h1, h2 and h3 (with the commas).

function myanimation(h1,h2,h3) {

        alert(h1 + h2 + h3);
        $("#h1").animate({"left": h1});
        $("#h2").animate({"left": h2});
    }

    var moves = new Array()
    moves[1] = [100,200,300];
    moves[2] = [300,200,100];
    moves[3] = [-500,-300,0];

    var i = 1;

    function animatenow(){
        myanimation(moves[i]);
        i++;
    }

$('#launch').click(function() {
        setInterval(animatenow, 5000);
    });

Answer 1

You are passing an array into myanimation, which corresponds to your h1 parameter. You aren't passing h2 or h3, so those are undefined.
