Question

I am using jQuery validation plugin for client side validation, but my validation does not work on my select box.

HTML

<select id="select" class="required">
    <option value="-1">Choose</option>
    <option value="child">test2</option>
</select>

JavaScript

$("#formid").validate({
    select: {
        required: function(element) {
            if ($("#select").val() == '-1') {
                return false;
            } else {
                return true;
            }
        }
    }
}); 

How do I get this working?

Answer 1

A simple way to fix this problem is to give the non valid option the value of "". Then simply call validate on your form and it will not submit when "Choose" is selected.

HTML

<form id="formid">
    <select name="select" class="required">
        <option value="">Choose</option>
        <option value="child">test2</option>
    </select>

    <input type="submit" />
</form>​

JavaScript

$("#formid").validate(); ​
