Question

I’ve got couple of “select” elements,
I need a true/false selector, whether one or any of them has a selected option with other than default which is “0” value.
Any ideas?

Answer 1

Why not to use filter?

$("select").filter(function(index) {
    return $(this).val() != "0";
})

if you wish to use it in condition

if($("select").filter(function(index) {
    return $(this).val() != "0";
}).size() > 0) {
    //Do something
}
