Validate empty value for dynamic HTML Select with unknown id and common class

Question

currently i have a form with dynamically generated select input.

Field name is an array in the form name="myfield[]" and they have a common class, example: class="unknownfield"

How can i, using Javascript or jQuery validate that every select on the Form has a selected which is not the default empty?

Answer 1

Something to the extent of:

$("form select").each(function() {
    if (this.value == "") //empty!

});
