[jQuery] Re: Validate selectedValue in a combobox

[ciupaz]

Thank you Jorn, now with the "name" attribute it's working.
A simple question.
For business rules I have to give the value "-1" to the "Select the
city" option.
Like this:

<select id="city" name="city">
                    <option value="-1">Select a city</option>
                    <option value="1">Milan</option>
                    <option value="2">Turin</option>
                    <option value="3">Rome</option>
                    <option value="4">Venice</option>
</select>

How can I validate in this case?
