Convert to uppercase as user types using javascript

Question

I want to convert lowercase chars to uppercase as the user types using javascript. Any suggestions are welcome.

I have tried the following:

$("#textbox").live('keypress', function (e) {
    if (e.which >= 97 && e.which <= 122) {
        var newKey = e.which - 32;
        // I have tried setting those
        e.keyCode = newKey;
        e.charCode = newKey;
    }
});

Answer 1

$("#textbox").bind('keyup', function (e) {
    if (e.which >= 97 && e.which <= 122) {
        var newKey = e.which - 32;
        // I have tried setting those
        e.keyCode = newKey;
        e.charCode = newKey;
    }

    $("#textbox").val(($("#textbox").val()).toUpperCase());
});
