HTML | DOM Input Date readOnly Property
Last Updated :
21 Sep, 2022
The Input Date readOnly property is used for setting or returning whether a date 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 Date readOnly property.
Syntax:
- For returning the readOnly property:
inputdateObject.readOnly
- For setting the readOnly property:
inputdateObject.readOnly = true|false
Property Value:
- true|false: It is used to specify whether the date field will be read-only or not. It is false by default.
Return Values: It returns a Boolean value which represents that the date field would be readonly or not.
The below program illustrates the Date readOnly property :
