The DOM Input Time readOnly Property in HTML DOM is used to set or return whether the Time Field should be read-only or not. It means that a user can not modify or changes a content already present in a particular Element (However, a user can tab to it, highlight it, and copy the text from it) whereas a JavaScript can be used to change the read-only value and make the input field editable.
Syntax:
Property Values:
- true: It defines that Time field is read only.
- false: It defines that Time field is not read only. It is false by default.
Return Value: It returns a boolean value which represent the Time field is read only or not.
