For detecting Enter, you could use the following code, which will work in all mainstream browsers. It uses the keypress event rather than keydown because Enter produces a printable character:

ele[i].onkeypress = function(evt) {
    evt = evt || window.event;
    var charCode = evt.keyCode || evt.which;
    if (charCode == 13) {
        alert("Enter");
        // Do stuff here
    }
};
