HTML | DOM Input DatetimeLocal readOnly Property

Difficulty Level : Basic
Last Updated : 10 Jun, 2021

The Input DatetimeLocal readOnly property is used to set or return whether a datetimeLocal field should be read-only, or not. Once a field has been declared read-only, it cannot be further modified. However, the read-only field can be tabbed, highlighted and can be used for copying text.
The HTML readonly attribute is reflected by the Input DatetimeLocal readOnly property.
Syntax:

To return the readOnly property:

datetimelocalObject.readOnly

To set the readOnly property:

datetimelocalObject.readOnly = true|false

Property Value:

true|false : It is used to specify whether the datetimeLocal field will be read-only or not.
