The Input DatetimeLocal defaultValue property is used to set or return the default value of a local DateTime field. This property is used to reflect the HTML value attribute. The main difference between the default value and value is that the default value indicates the default value and the value contains the current value after making some changes. This property is useful to find out whether the DatetimeLocal field has been changed or not.
Syntax:
- It is used to return the defaultValue property.
datetimelocalObject.defaultValue
- It is used to set the defaultValue property.
datetimelocalObject.defaultValue = value
Property Values: It contains single property “value” which defines the default value for the local DateTime field.
Return Value: It returns a string value that represents the default value of the local DateTime field.
