Very hackily, you can just check its selectedIndex; since most browsers ensure that there is something selected if at all possible, it will only be -1 if there are no selectable options.

Native javascript solution:

!!document.getElementById('jiveviewthreadsform-filter').children.length

(Please do not overuse jQuery, thanks)

$('#input1 option').length > 0

Where #input is the ID of the select element you are running this test against.

var menu = getElementById("select_id");
if(menu.options.length) {
    // has children
} else {
    // empty
}

var hasOptions = !!$('#theSelect option').filter(function() { return !this.disabled; }).length;

maybe? This looks for <option> elements that are not disabled.
