VisualizaçõesWrapped Img is not being picked up in JS
I've been stuck on this for a few days. I've tried different selectors and unwrapping the img in the div if that was the problem but no luck. I've been trying to make an accordion. I'm trying to add a class of "rotate" to the img with the class of "arrow". So that when the question tag is clicked, the arrow img will also rotate.
const questionTag = document.querySelectorAll('.question')
questionTag.forEach(questionTag => {
questionTag.addEventListener('click', () => {
if (questionTag.classList.contains('open')) {
questionTag.classList.remove('open');
} else {
const questionTagOpen = document.querySelectorAll('.open');
questionTagOpen.forEach((questionTagOpen) => {
questionTagOpen.classList.remove('open');
});
questionTag.classList.add('open');
}
});
});.question + .answer {
display: none;
overflow: hidden;
transition: all ease 1s;
}
.question.open + .answer {
display: block;
}
.arrow.rotate {
transform: rotate(180deg);
}<div class="container">
<div class="question">How many team members can I invite?
<img class="arrow" src="./images/icon-arrow-down.svg">
</div>
<div class="answer">You can invite up to 2 additional users on the Free plan. There is no limit on
team members for the Premium plan.</div>
</div>

You're missing [0] in your code.
The arrowTag comes from document.querySelectorAll(), which returns a NodeList, you need to specify the element from that NodeList:
var questionTag = document.querySelectorAll('.question')
questionTag.forEach(questionTag => {
questionTag.addEventListener('click', () => {
if (questionTag.classList.contains('open')) {
questionTag.classList.remove('open');
} else {
const questionTagOpen = document.querySelectorAll('.open');
questionTagOpen.forEach((questionTagOpen) => {
questionTagOpen.classList.remove('open');
});
questionTag.classList.add('open');
}
});
var arrowTag = document.querySelectorAll('img.arrow')
questionTag.addEventListener('click', () => {
arrowTag[0].classList.toggle('rotate'); // missing [0] added here
});
});
The addEventListener function is applied to an event target.
Thus, you cannot apply it to the NodeList, which is stored in your arrowTag:
