FormData and checkboxes

Question

Currently when creating a FormData object, a checked checkbox is added with a value of \"on\", and an unchecked checkbox is not passed at all.

Do I have to

Answer 1

Try this:

var checkbox = $("#myForm").find("input[type=checkbox]");
$.each(checkbox, function(key, val) {
    formData.append($(val).attr('name'), this.is(':checked'))
});

It always adds the field to FormData with either a value of true when checked, or false when unchecked.
