React js Checkbox disable after checked
React js Checkbox disable after checked: In React.js, you can disable a checkbox after it has been checked by using the state and event handling. First, define a state variable to track the checkbox's checked status.
Then, create an event handler that updates the state when the checkbox is clicked. In the render method, set the "disabled" attribute of the checkbox based on the state value.
When the checkbox is checked, the state will be updated, and the checkbox will become disabled, preventing further changes. By utilizing state and event handling, you can easily implement a disable functionality for a checkbox in React.js.

How can I disable a checkbox in React.js after it has been checked?
The given code is a React.js component that renders a checkbox. When the checkbox is checked, it becomes disabled and cannot be unchecked. It utilizes the useState hook from React to manage the state of the checkbox.
Initially, the isChecked state is set to false, indicating that the checkbox is not checked. The isDisabled state is also set to false, indicating that the checkbox is initially enabled.
The handleCheckboxChange function is called whenever the checkbox is clicked. It toggles the isChecked state using setIsChecked and sets the isDisabled state to true using setIsDisabled, disabling the checkbox.
The checkbox element in the JSX code has the checked attribute bound to the isChecked state and the disabled attribute bound to the isDisabled state. The onChange event is also bound to the handleCheckboxChange function.
Once the checkbox is checked, it becomes disabled, preventing further changes to its checked state.
