We’ll implement a character count feature in a textarea element using JavaScript. This feature will display a real-time character count to users as they type, providing instant feedback and helping them stay within the allowed limit.

<textarea class="form-control z-depth-1" name="describe_problem" id="describe_problem" maxlength="512" onkeyup="countNoCharacters()" rows="3" placeholder="Write here..."></textarea>
<span id="characterNoCount"></span>

<script>
function countNoCharacters() {
    const description = document.getElementById("describe_problem");
    const characterCount = document.getElementById("characterNoCount");
    const remainingCharacters = 512 - description.value.length;
    characterCount.innerText = `${description.value.length} / 512 characters. ${remainingCharacters} remaining.`;
}
</script>

We start with a <textarea> element with the maxlength attribute set to 512 characters to define the character limit.

We include a <span> element with the id “characterNoCount” to display the character count.

The countNoCharacters JavaScript function is called whenever a key is released (onkeyup event) in the textarea.

Inside the function, we calculate the remaining characters and update the content of the <span> element to display the current character count and the remaining characters.
