Word Counter with React

by vsasikalabe Updated: Jan 24, 2023

Actually, the Word Count utility can display the count of words.First we have to initialize the total no of words in the box. Based on this we have to write the sentence.The sentence will get stop after the point.For that we are using first handle,handle submit and second handle.Limwords will givs us the limited words.If we will type extra words the error will be shown like 'you exceeded the maximum no of words'.Suppose we will type less words the hints will be 'you still have to write (result) words'.

Preview of the output that you will get on running this code from your IDE.

Code:

In this solution we use the React library.

  }
  firstHandle(e) {
    this.setState({
      firstValue: e.target.value
    });
  }

  handleSubmit(e) {
    e.preventDefault();
    this.setState({
      needWords: this.state.firstValue,
      secondValue: ""
    });
  }

  secondHandle(event) {
    //calculate the word count first itself and use them in other manipulations
    const wordCount =
      event.target.value === "" ? 0 : event.target.value.split(" ").length;
    this.setState({
      secondValue: event.target.value,

  }

  render() {
    var result = this.state.needWords - this.state.wordCount;
    let tooManyChars;
    if (result < 0) {
      const tooManyCharStyle = {
        color: "red"
      };
      tooManyChars = (
        <p style={tooManyCharStyle}>
          You exceeded the maximum number of words!!
        </p>
      );
    }
    return (
      <div>
        <form onSubmit={this.handleSubmit}>
          <p>How many words do you have to write?</p>
          <input
            type="text"
            value={this.state.firstValue}
            onChange={this.firstHandle}
          />
          <button type="submit">Go</button>
        </form>
        <form>
          <p>You still have to write {result} words</p>
          <textarea
            type="text"
            value={this.state.secondValue}
            onChange={this.secondHandle}
            maxLength={this.state.limWords}
          />
          {tooManyChars}
        </form>
      </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.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in App.js file(remove the earlier code from App.js).
Import React and React-Dom.
Add const rootElement = document.getElementById("root"),ReactDOM.render(<App />, rootElement),export default App to the end of the line.
Open the terminal from IDE.
npm start to run the file.
