Dropdown validation does not work

Question

it's my validation for chosen enabled select:

SellerDropDownList: {
    required: {
        depends: function (element) {
            return $("#SellerDropDownList").val() == "-1";
        }
    }
}

Default value is -1, but it does not work and when I click submit button; It passes validation while chosen selected value is -1.

Answer 1

Reading the documentation, required does not work the way you are trying to use it.

One option I found to work is min:

    SellerDropDownList: {
        min: 0
    },

Another possible way is to define your own rule ("not equal") described under this question.
