Table of contents

  • Install and create a new React app.
  • Import react component.
  • Create a Component.

Let’s start with the first step.

Step 1: Install and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import react component.

After installing, you have to import your React component. To do this, add the following line to the top of your component file.

import React, { useRef } from 'react';

Step 3: Create a Component.

You can use type="hidden" to add hidden field in react js.

<form>
      <input 
        type="hidden" 
        name="hiddenField" 
        ref={hiddenInputRef} 
        defaultValue="initialValue" 
      />
      <button type="button" onClick={handleClick}>
        Update Hidden Value via Ref
      </button>
</form>

Define the add hidden field example.

The below code is an example of a React. You have to import react and set type="hidden" to add hidden field in react js.

App.js

import React, { useRef } from 'react';

const App = () => {
  const hiddenInputRef = useRef(null);

  const handleClick = () => {
    if (hiddenInputRef.current) {
      hiddenInputRef.current.value = 'updatedValue';
    }
  };

  return (
    <form>
      <input 
        type="hidden" 
        name="hiddenField" 
        ref={hiddenInputRef} 
        defaultValue="initialValue" 
      />
      <button type="button" onClick={handleClick}>
        Update Hidden Value via Ref
      </button>
    </form>
  );
};

export default App;

In the above code example, I have used the type="hidden" and add hidden field in react js.
