Input Datetime readOnly Property

Set a datetime field to read-only:

document.getElementById("myDatetime").readOnly = true;

Description

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.
