React Js focus Next input field on Enter
React Js focus Next input field on Enter:In React.js, to focus the next input field when the "Enter" key is pressed, you can utilize the onKeyDown event handler.
First, assign a ref to each input field using the useRef hook. Then, in the event handler, check if the pressed key is "Enter" (key code 13). If it is, use the current property of the next input field's ref to focus it.
Keep in mind that you may need to handle edge cases, such as the last input field in the form. In summary, with proper event handling and the ref concept, you can achieve the desired functionality in React.js.

How can you use React.js to automatically focus on the next input field when the "Enter" key is pressed?
This code snippet demonstrates how to implement a functionality in ReactJS that focuses on the next input field when the "Enter" key is pressed. It starts by using the useRef hook to create a reference to the input fields.
The handleKeyDown function is called when a key is pressed within an input field. If the pressed key is "Enter," it prevents the default behavior and calculates the index of the next input field. If there is a next input field, it sets the focus on it using the focus() method. Otherwise, it sets the focus on the first input field.
The handleInputChange function can be used to handle any input change logic. In this example, it logs the input value to the console.
The addInputRef function adds the input field reference to the inputRefs array. If the reference is not already present, it adds it to the array and assigns the handleKeyDown function to the input field's onkeydown event if it's the last input field.
Finally, the App component renders a container with three input fields. Each input field has a reference assigned and an onChange event handler that calls the handleInputChange function.
When the code is executed, pressing "Enter" in an input field will shift the focus to the next input field, and if the last input field is reached, it will cycle back to the first input field.
