I am trying to figure out how to properly apply a CSS class to an HTML element based on that elements data-attribute using jQuery.
What I am trying to achieve is the following:
The issue I am currently having is once I select more then one "fruit", an element that was previously selected, will be selected even though it has one or more of the selected fruits.
$('a.fruit').click(function() {
$(this).toggleClass("active");
var fruits = $(this).data("fruit");
$("div.store[data-fruits~='" + fruits + "']").toggleClass("active");
});
body {
margin: auto;
max-width: 40em;
font-family: "Segoe UI";
background-color: #FFFFFF;
}
ul {
list-style-type: none;
padding: 0;
}
.fruit.active::after {
content: "✔️";
margin-left: .5rem;
}
.store {
position: relative;
display: inline-block;
width: 10rem;
padding: 1rem;
border-radius: 1rem;
border: 1px solid black;
text-align: center;
margin: 0 0.5rem 0.5rem 0;
bottom: 0;
-webkit-transition: all .2s ease;
-moz-transition: all .2s ease;
-ms-transition: all .2s ease;
-o-transition: all .2s ease;
transition: all .2s ease;
}
.store span {
display: block;
font-weight: bold;
width: 100%;
margin-bottom: 1rem;
text-decoration: underline;
}
.store-container {
position: relative;
}
.store.active {
position: relative;
box-shadow: 3px 3px 5px grey;
bottom: 5px;
}

<div>

<div class="store" data-fruits="orange grape peach">
<span>Store F</span>🍊🍇🍑

<div class="store" data-fruits="grape peach">
<span>Store G</span>🍇🍑
</div>
<div class="store" data-fruits="peach">
<span>Store H</span>🍑
</div>
</div>
</div>
Please refer to the JSFiddle for my example code so far.
Thank you in advance for any guidance with this issue.

I used your Fiddle. This might be a little verbose but seems to work. I remove active class from .store each time something is clicked to help fix your problem.
$('a.fruit').click(function () {
$(this).toggleClass("active");
if ($('.fruit[data-fruit="all"]').hasClass('active')) {
$(".store").addClass("active");
} else {
$(".store").removeClass("active");
$('a.fruit').each(function () {
if ($(this).hasClass("active")) {
var fruit = $(this).data("fruit");
$(".store").each(function () {
if ($(this).data("fruits").includes(fruit)) {
$(this).addClass("active");
}
});
}
});
}
});
