In this tutorial we will learn word, character, and line count in text area using HTML, CSS, and JS.


Word, Character, and Line Count in Text Area Using HTML, CSS, and JS


Word, Character, and Line Count in Text Area Using HTML, CSS, and JS

Let's see an example :


<!DOCTYPE html>
  <meta charset="UTF-8">
  <title>Word, Character, and Line Count in Text Area Using HTML, CSS, and JS</title>
    textarea {
      width: 100%;
      height: 200px;
      margin-bottom: 10px;
  <textarea id="textAreaId"></textarea>
  <p>Total Word Count: <span id="word-counts">0</span></p>
  <p>Total Character Count: <span id="char-counts">0</span></p>
  <p>Total Line Count: <span id="line-counts">0</span></p>

    const textBoxArea = document.getElementById('textAreaId');
    const wordCountArea = document.getElementById('word-counts');
    const charCountArea = document.getElementById('char-counts');
    const lineCountArea = document.getElementById('line-counts');

    textBoxArea.addEventListener('input', function() {
      let text = textBoxArea.value;

      // number of words count
      let words = text.match(/\S+/g);
      wordCountArea.innerText = words ? words.length : 0;

      // number of characters count
      charCountArea.innerText = text.length;

      // number of lines count
      let lines = text.split(/\r?\n/);
      lineCountArea.innerText = lines.length;

Here, the input event is used to check value when a user types into the textarea. The event listener updates the word count, character count, and line count based on the current value of the text area. The regular expressions /\S+/g and /\r?\n/ are used to split the text into words and lines, respectively.


Keep that in mind , this code only coungt the words, characters, and lines in the text that is now visible in the text box (text area). If the user scrolls down or expands the text area to show more text, the counts will not automatically update.
