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.

The <input type="checkbox"> defines a checkbox. The checkbox is shown as a square box that is ticked (checked) when activated. Checkboxes are used to let a user select one or more options of a limited number of choices. Tip: Always add the <label> tag for best accessibility practices!

The state can be changed by providing the new state value or an updater function. The updater function takes the current state and returns the new state. The state related to a checkbox input is a boolean. When the state is false the checkbox is unchecked, when the state is true the checkbox is checked.

Users can follow the syntax below to use the onclick event with checkbox input. In the above syntax, we have passed the function execution expression as a value of the onclick event attribute. The function is the name of the function to invoke when the user clicks the checkbox.
