Definition and Usage
The readOnly property sets or returns whether a datetime field should be read-only, or not.
A read-only field cannot be modified. However, a user can tab to it, highlight it, and copy the text from it.
This property reflects the HTML readonly attribute.
Tip: To prevent the user from interacting with the field, use the disabled property instead.
