Regulate Checkbox Release For Free

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 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.

Use the preventDefault() method to stop the default behavior of a particular element. Learn more about preventDefault() method.

By default, the Checkbox is in an uncontrolled state. The Checkbox provides options for controlling the Value and Checked state. It supports setting it's boolean value using either value or checked prop. Note that if you provide both props, the value prop will be passed to the underlying input element.

The CheckBox options can be restricted from being changed to the checked or unchecked state by using the CheckBoxClick event when the CheckBox cell is clicked.

To disable a checkbox, use the disabled attribute in the <input> tag.

The disabled property sets or returns whether a checkbox should be disabled, or not. A disabled element is unusable and un-clickable. Disabled elements are usually rendered in gray by default in browsers.

Checkboxes cannot be set to readonly using standard HTML attributes. However, alternative approaches like using the disabled attribute or CSS properties like pointer-events can mimic the read-only behavior for checkboxes. But you can achieve it by using these approaches.
