The CheckBox component for ReactJS represents a check box that allows the end-user to select a true, false or indeterminate condition.
Refer to ReactJS Getting Started before you start with this help topic.
The CheckBox component for ReactJS requires the following imports.
Then we create our component class. Properties and methods are put as ReactJS props.
Finally we render our class in the desired HTML element:
In order to bind to any event, change any property or call any method, we need a reference to the component.
For that we use the ReactJS "ref" Callback Attribute:
Now, when we have a reference, we need to call the desired event/property/method.
This is done in the componentDidMount() ReactJS Component Lifecycle method.
The change event is triggered when the checkbox's state changes.
The following example demonstrates how to add an event listener:
This is how you call methods & props:
Every component have a method setOptions which accepts a object as an argument. This object contains component settings.
Every component also have a method getOptions which returns a object containing the component settings.
The following example demonstrates how to create a CheckBox component.
The following example demonstrates the CheckBox in the indeterminate state. Use checked: null property.
