HTML DOM Input Range defaultValue Property

Last Updated : 23 Sep, 2022

The Input Range defaultValue Property in HTML DOM is used to set or return the default value of the slider control. 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 range field has been changed or not.

Syntax:

It returns the Input Range defaultValue property.

rangeObject.defaultValue

It is used to set the Input range defaultValue property.

rangeObject.defaultValue = value

Property Values: It contains a single property, i.e, the value that defines the default value for the range field.

Return Value: It returns a string value that represents the default value of the range field.

Example: This example illustrates how to return the Input Range defaultValue property.
