IE8 Jquery Javascript “Error: Object required” Bug

Question

IE8 throws an "Error: Object required" message (error in the actual jquery library script, not my javascript file) when the switch statement in this function runs. This code works in IE6, IE7, FF3, and Safari... Any ideas? Does it have something to do with the '$(this)' selector in the switch? Thanks!

function totshirts(){
    $('.shirt-totals input').val('0');
    var cxs = 0;
    var cs = 0;
    var cm = 0;
    $.each($('select.size'), function() {
        switch($(this).val()){
            case "cxs":
                cxs ++;
                $('input[name="cxs"]').val(cxs);
                break;
            case "cs":
                cs ++;
                $('input[name="cs"]').val(cs);
                break;
            case "cm":
                cm ++;
                $('input[name="cm"]').val(cm);
                break;
        }
    });
}

Answer 1

I upgraded the jQuery library from 1.2.6 to 1.3.2 and this solved the problem. Didn't realize I had an old version- oops.

Thanks for your help all!

Oh noes, don't do it that way at all.

Do something more along the lines of this:

$('.shirt-totals input').val('0');
$('select.size').each(function() {
 var name = $(this).attr('name');
 var currVal = parseInt($("input[name='"+name+"']").val());
 $("input[name='"+name+"']").val(currVal+1);
});

As a sidenote, I tend to find that jQuery seems to deal with single quotes better than doubles in when doing the "equals" comparison.
