React Js Set Placeholder on Input Field

React Js Set Placeholder on Input Field:In ReactJS, you can set a placeholder on an input field using the "placeholder" prop. To make it dynamic, assign the prop a variable that holds the desired placeholder text. For conditional behavior, create a logic to determine the placeholder value based on certain conditions, and then apply it to the input field's prop accordingly. This allows you to display relevant placeholder text depending on the situation, enhancing the user experience by providing context-sensitive input guidance.

How can placeholder prop on an input field in Reactjs be set conditionally?

This React.js code snippet demonstrates how to conditionally set the "placeholder" attribute for an input field. Depending on the "isLogged" state, the placeholder will show either "Welcome back!" or "Please log in". The state changes when the "Log In" or "Log Out" button is clicked, toggling the login status. This provides a dynamic user experience by adapting the input field's placeholder based on the user's authentication status.

        <div className='container'>
          <h3>React Js conditionally set the placeholder prop on an input field</h3>
          <input
            type="text"
            placeholder={isLogged ? 'Welcome back!' : 'Please log in'}
          />
          <button onClick={() => setIsLogged(!isLogged)}>
            {isLogged ? 'Log Out' : 'Log In'}
          </button>
        </div>
