Submit form only if at least one checkbox is checked

Question

i\'m triyng to validate a form. In this form you\'ve to choose at least one element by checkboxes, and I can\'t be sure about their quantity (it depends by elements number).

Answer 1

The :checked selector will Match all elements that are checked or selected.

You could try this

$("#subm").click(function(e){
        if($(".roomselect:checked").length == 0){
            e.preventDefault();
        }
    });
