Adjust the volume of media using JavaScript in PhoneGap

In our previous section, we made our own control buttons using JavaScript. In this section, we will learn how we can adjust the volume using JavaScript in PhoneGap. We will create a volume slider that will control the volume of our media. The volume is the property of our player, which can be easily controlled through the user interface.

These are the following steps used to create a volume slider in PhoneGap:

1) Create index2.html file

We will create another html file index2.html. This file will contain the same code as present in the index.html file. We will make changes in this file so that our index.html file remains unchanged.
