React Js Get Multiple Checkbox Value
React Js Get Multiple Checkbox Value:To get multiple checkbox values in React.js, you can create a state variable to track the selected checkboxes.
Initialize it as an empty array. Then, attach an event handler to each checkbox to update the state when it is checked or unchecked. In the event handler, check the checkbox's status and add or remove its value from the state array accordingly.
Finally, you can access the selected checkbox values by referencing the state array. This approach allows you to dynamically track and retrieve the values of multiple checkboxes in a React.js component.

How to Get Multiple Checkbox values in React.js
In this React.js code snippet, a functional component called App is defined. It uses the useState hook to declare two state variables: checkboxes and selectedValues.
The checkboxes variable is an array that keeps track of selected checkbox values, while selectedValues is a string holding the comma-separated selected values.
The handleCheckboxChange function is called when a checkbox is checked or unchecked, adding or removing the value from the checkboxes state accordingly.
The handleSubmit function prevents default form submission, sets the selectedValues state by joining the checkbox values, and displays them if not empty. Finally, the App component is rendered using ReactDOM.render within a container div.

How can I implement a React checkbox that, when checked, adds a specific value to an array?
This React script creates a checkbox list for vegetables. When a checkbox is checked, its value (vegetable name) is added to the "checkboxValues" array using React's useState hook. If the checkbox is unchecked, its value is removed from the array. The selected vegetable names are then displayed below the checkbox list.
