How to use checkbox input in ReactJS app?

If you are new in react js then you want to see how to use checkbox in react app. but it's very easy to use checkbox input in react js app. you can use it as you use in html and you have to write change event on it. using that change event you have to store value into form state. so you can get that data on submit.

Why can't I call the onchange handler in react?

React.renderComponent(CrossoutCheckbox({text: "Text Text", complete: false}), mountNode); Solution: Using checked doesn't let the underlying value change (apparently) and thus doesn't call the onChange handler.

How do I control a checkbox?

You can control the checkbox with the checked and onChange props: A checkbox input can only have two states in a form: checked or unchecked. It either submits its value or doesn't. Visually, there are three states a checkbox can be in: checked, unchecked, or indeterminate.

What happens if you uncheck a checkbox in onchange?

If we use onChange to send checkbox values, there is one issue. If we uncheck any of the checkboxes, the function checkValue will again be called, and we will receive the value of the checkbox unchecked by the user, as shown below. As shown above, when we uncheck box 1, the value of box 1 is sent again to the function.
