I am using a monthpicker input (similar to jQuery UI datepicker) for a credit card expiration field.
I need to suppress the iPhone keypad because it hides the month picker.
I have tried setting the field to readonly and it is not an acceptable solution - in Safari iOS 5.1 readonly fields are skipped over in keyboard navigation (prev/next buttons on the keypad). Blurring the field is also not acceptable because it triggers validation (we are also using jQuery validation).
Is there a way to turn off the iPhone keyboard on a single field without setting it readonly or blurring it?
I haven't come across the way to hide keyboard. But have you thought alternate way of displaying "input". One option would be using <input type="month" />
which brings the native month picker in iOS5.
Second option would be styling eg. span element as input element (-webkit-appearance not working on iOS), and adding tabindex for the element. This could also work, although I'm not aware of the month picker you're using.
Third option - can't you prevent the validation process when blurring the field is triggered manually?
