Tell us what’s happening:

I am unable to update char-count using input event listener on text area. Attempted to implement a snippet gathered from MDN example of input event listener ( Element: input event - Web APIs | MDN ) but am stuck on how to implement it correctly to change number in real time.

Your code so far

<!-- file: index.html -->
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Real Time Counter</title>
</head>

<body>
    <textarea id = text-input>

    </textarea id = text-input>
    <p id = char-count> Character Count: 0/50
    </p>
</body>


</html>

/* file: styles.css */


/* file: script.js */
/*

R

P 
*/
//grabbed the text input box
let textInput = document.getElementById("text-input")
//grabbed the char count text
let charCount = document.getElementById("char-count")

//let countChar = textInput.value.trim().length

//const myText = `Character Count: ${countChar}/50`

//charCount.innerText = myText

textInput.addEventListener("input", updateValue);

function updateValue(e) {
  charCount.innerText = `Character Count: ${e.target.value.trim().length}/50`
}
//let str = document.getElementById('text-input').innerHTML

Hi @d3911ready,

An id attribute’s value must be unique, and all attribute values should be enclosed in quotes.

Do attributes belong in an HTML element’s closing tag?

Happy coding

I fixed the issues highlighted in your comment and still facing issues with not having the char count not update properly as I input text in real time

Have you added your script file in your html file?

I did not. this worked thank you. The number updates in code pen but not in FCC when I click run is there a reason for that?

I am not able to pass step 5 even though on code pen my code is changing text color

/*

//grabbed the text input box
let textInput = document.getElementById("text-input")
//grabbed the char count text
let charCount = document.getElementById("char-count")

textInput.addEventListener("input", updateValue);

function updateValue(e) {
  if(e.target.value.trim().length >= 50)
  {
    textInput.style.color = 'red';
  }
  else if(e.target.value.trim().length < 50){ textInput.style.color = 'black';}
  charCount.innerText = `Character Count: ${e.target.value.trim().length}/50`
}
