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.

Create the function checkClickFunc() which is to be executed upon clicking the checkbox. Using the ?getElementById()? method, retrieve the checkbox by its id, ?agree?. Check the checkbox's status by using the ?checked? attribute. If it's ?true?, show an alert message ?Checkbox is clicked?.

Whenever the user checks or uncheck any checkbox, it invokes the handleChage() function. In the handleChange() function, we check if the checkbox is checked and add the checkbox value to the allChecked array. If the checkbox is unchecked, we remove the checkbox value from the allChecked array.
