[jQuery] Validate textbox on at least one checkbox selected

[ciupaz]

Hi all,
I have a textbox and 2 checkbox, and I'd like to validate the textbox
if at least one of the two checkbox is selected.
If is just one checkbox, I'll write:

myTextboxl: {
                    required: '#myFirstCheckbox:checked'
                }


but in the case of 2 checkbox, how can I solve?

Thanks a lot.

Louis
