Checkbox event handling using pure Javascript Now what we need to do is to attach an event to the checkbox so it checks its state each time it's changed and show the message if it has been unchecked , notice I added a checked property to the checkbox so it is checked by default.

There is no HTML-only method of representing a checkbox's unchecked state (e.g. value=unchecked ). If you wanted to submit a default value for the checkbox when it is unchecked, you could include JavaScript to create a <input type="hidden"> within the form with a value indicating an unchecked state.

Create a state variable (an object) that contains any checked checkbox, so initially it will be empty, when a checkbox is checked, add it to the state variable, and if the special uncheck all box is checked, clear the state variable to its default (an object).
