by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we're going to see how to implement input auto-tab in React with simple steps. React-auto-tab is a react.js package that brings several tabbing features with little change to your code. React-input-auto-tab is a module that easily lets you drop it into your existing project and get the benefits of HTML input element with auto tabbing functionality. It's a plug and play component that'll fit in your workflow if your using standalone React or React with Redux. To implement this task, use the ready-made code snippet below by just copying the code and paste it in your IDE with required libraries added below.

const autoTab = e => {
  const BACKSPACE_KEY = 8;
  const DELETE_KEY = 46;
  let tabindex = $(e.target).attr("tabindex") || 0;
  tabindex = Number(tabindex);
  if (e.keyCode === BACKSPACE_KEY) {
    tabindex -= 1;
  } else if (e.keyCode !== DELETE_KEY) {
    tabindex += 1;
  }
  const elem = $("[tabindex=" + tabindex + "]");
  if (elem[0]) {
    elem.focus();
  }
};

const blocks = Array.from({ length: 10 }, (element, index) => (
  <input
    className="block"
    tabIndex={index}
    key={index}
    maxLength={1}
    onKeyUp={autoTab}
  />
));

const autoTab = e => {
  const BACKSPACE_KEY = 8;
  const DELETE_KEY = 46;
  let tabindex = $(e.target).attr("data-index") || 0;
  tabindex = Number(tabindex);
  let elem = null;
  if (e.keyCode === BACKSPACE_KEY) {
    elem = tabindex > 0 && elemRefs[tabindex - 1];
  } else if (e.keyCode !== DELETE_KEY) {
    elem = tabindex < elemRefs.length - 1 && elemRefs[tabindex + 1];
  }
  if (elem) {
    elem.current.focus();
  }
};

const Input = props => {
  const ref = React.createRef();
  elemRefs.push(ref);
  return (
    <input
      className="block"
      data-index={props.index}
      ref={ref}
      maxLength={1}
      onKeyUp={props.autoTab}
    />
  );
};

const blocks = Array.from({ length: 10 }, (element, index) => (
  <Input key={index} index={index} autoTab={autoTab} />
));

const App = () => <div className="App">{blocks}</div>;

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Install npm install jquery.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in index.js file(above code mixed with two set of codes, one is original another one is edited, you have to use edited one so please refer demo given below).
Open the terminal from IDE.
npm start to run the file.

You can also refer this url 'DEMO' for getting the above output.
