React how set count text value 0 for empty box

February 16, 2022

Right now my empty text box showing count 1. see the screenshot below:

I want to show 0 value for empty box. how to do that? here is my code:

export default function TextFrom(props) {
  const handelUpClick = () => {
    let newtext = text.toUpperCase();
    setText(newtext);
  };

  const handelLoClick = () => {
    let newtext = text.toLowerCase();
    setText(newtext);
  };

  const handleOnChange = (event) => {
    setText(event.target.value);
  };

  const [text, setText] = useState("");

  return (
    <>
    ..my html code
     <h1>your text summary</h1>
        <p>
          {text.split(" ").length} words and {text.length} character
       </p>
    <>

>Solution :

The problem here is that split returns [""] when called on an empty string, and the length of that array is indeed 1. To counteract this, you can replace the {text.split(" ").length} part of your code with {text.trim() === '' ? 0 : text.split(" ").length} so that the case where the input is only whitespace is taken care of.
