Enhance Your Website with HTML and JavaScript

Here is the code snippet I am working with:

sTAT **javascript**
var acc = document.getElementsByClassName("item-wrapper");
var i;
for (i = 0; i < acc.length; i++) {
acc[i].onclick = function(){
this.classList.toggle("selected");
this.nextElementSibling.classList.toggle("show");
}
}
});

CSS

.accordion-menu{
    list-style: none;margin: 0;padding: 0;
}
.accordion-menu a {
    text-decoration: none;
    background: none;
    font-family: arial;
}

.accordion-menu a:hover,
.accordion-menu a:visited,
.accordion-menu a:active,
.accordion-menu a:focus{
    background: none;
}

/* Rest of the CSS styles have been preserved from original text */ 

HTML

<div class="module_menu">
    <div class="module-content clearfix">
        <ul class="accordion-menu" id="demo-menu">
            <li class="item-wrapper">
                <a href="/category1">Category 1</a> 
            </li>
            /* Additional HTML markup has been condensed */
            <li class="item-wrapper">
                <a href="/category4">Category 4</a>
            </li>
        </ul>
    </div>
</div>

In order to show the card when clicking the item-wrapper div and ensure that there is an ul-wrapper div tag behind it, you can add specific conditions in JavaScript. Thank you.

Answer №1

Your question is a bit ambiguous, but upon reviewing your code, I believe I have a potential solution for you.

Simply adding the "show" class to your ul-wrapper does not instruct the DOM to display that element. You need to utilize the "display" attribute for that purpose.

Check out this updated JSFiddle link for reference!

var elements = document.getElementsByClassName("item-wrapper");
for (let element of elements) {
    element.addEventListener('click', function() {
        this.classList.toggle("selected");
        if (this.nextElementSibling.style.display === 'none') {
            this.nextElementSibling.style.display = 'block';
        } else {
            this.nextElementSibling.style.display = 'none';
        }
    });
}
