Hi, is this not doing what the test demands? I’m failing test #6.

Your code so far

<!-- file: index.html -->

.capped {

/* file: script.js */
    const textArea = document.getElementById("text-input");
const textDisplay = document.getElementById("char-count");

textArea.addEventListener("input", () => {
  const currentLength = textArea.value.length;
  textDisplay.textContent = `Character Count: ${currentLength}/50`;
  if (currentLength >= 50) {
    textDisplay.classList.add("capped");
    textArea.value = textArea.value.substring(0, 49);
  }
});

the character count is not being adjusted tho

that I don’t think it makes tests fail tho

check the length of the string after trimming

I think it’s slightly bugged because I passed the test when it allows 51/50 characters.

const textArea = document.getElementById("text-input");
const textDisplay = document.getElementById("char-count");

textArea.addEventListener("input", () => {
  const currentLength = textArea.value.length;
  textDisplay.textContent = `Character Count: ${currentLength}/50`;
  if (currentLength >= 50) {
    textDisplay.classList.add("capped");
    textArea.value = textArea.value.slice(0, 50);
  }
});

I would double check the length of textArea.value after slicing, or douuble check slice syntax: Array.prototype.slice() - JavaScript | MDN

that’s not 51 characters

5

right, I just mean the char count says 51 but it lets me pass. Thank you for your help with this though, DOM stuff is tricky, but the lessons are helping a lot.

if you want to report it as a bug, you can, it’s the same issue I pointed out earlier

Thank you for helping make FCC better. Bugs can be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.
