React Js Post Checkbox data to API
React Js Post Checkbox data to API:To post checkbox data to an API using ReactJS, you would first create a form with checkboxes and a submit button. Each checkbox should be associated with a corresponding state variable. When the form is submitted, you would handle the event by capturing the state values of the checkboxes and constructing a payload object. Next, you would use the fetch or axios library to send a POST request to the API endpoint, passing the payload object as the request body. Finally, you can handle the API response and update the UI accordingly. This allows you to send the checkbox data from your ReactJS application to the API.

How can I use Reactjs to send checkbox data to an API endpoint?
This code snippet demonstrates how to use ReactJS to post checkbox data to an API. The component App defines a state variable selectedRivers using the useState hook to store the selected river names. The available rivers are defined in an array. When a checkbox is checked or unchecked, the handleCheckboxChange function is called to update the selectedRivers state accordingly.
Upon form submission, the handleSubmit function is triggered. It prevents the default form behavior, performs a POST request to an API endpoint using the selected rivers data (selectedRivers), and handles the response or error using axios, an HTTP client library.
The rendered UI displays a list of rivers as checkboxes. The checked property is set based on whether the river name exists in the selectedRivers array. When the form is submitted, the selected rivers are sent to the API endpoint.
