Add class to closest element of e.target – Jquery

I’m trying to add a shake effect to a font-awesome icon whenever hovering over the hyperlink beside it.
The HTML looks like this:

<div class="icon-hyperlink">
     <span>
          <i class="fas fa-phone p-2"></i>
     </span>

     <span>
          <a href="tel:XXXX XX XX XX">John: XXXX XX XX XX</a>
     </span>
</div>

I’m trying to add the class fa-shake to the matching i with class "fas", and remove it when not hovering.

I’m not super well versed in jQuery, but I read a lot of the documentation and other stackoverflow articles getting this to work, to no avail.

My current code is:

$(document).ready(function() {
     $(".icon-hyperlink a").hover(function(e) {
          e.target.closest(".fas").addClass("fa-shake");
     }, function(e) {
          e.target.closest(".fas").removeClass("fa-shake");     
     });
});

The error I’m getting is:

Uncaught TypeError: Cannot read properties of null (reading ‘addClass’)

I also tried the following:

$(e.target.closest(".fas")).addClass("fa-shake");

That gives me no errors, but it also doesn’t work.

    You need to traverse up to a shared parent, then find the icon

    $(".icon-hyperlink a").hover(
  function () {
    $(this).closest(".icon-hyperlink").find(".fas").addClass("fa-shake");
  },
  function () {
    $(this).closest(".icon-hyperlink").find(".fas").removeClass("fa-shake");
  }
);

    As mentioned above, the <span> elements seem unnecessary and just complicate the matter.

    Also, it’s 2022 and you probably don’t need jQuery.

    document.addEventListener("mouseenter", (e) => {
  if (e.target.matches(".icon-hyperlink a")) {
    e.target
      .closest(".icon-hyperlink")
      .querySelector(".fas")
      ?.classList.add("fa-shake");
  }
});

document.addEventListener("mouseleave", (e) => {
  if (e.target.matches(".icon-hyperlink a")) {
    e.target
      .closest(".icon-hyperlink")
      .querySelector(".fas")
      ?.classList.remove("fa-shake");
  }
});

    You can use .parents() and .find() instead to select the .fas element you’re trying to find.

    Just ignore the html and css changes I made, they’re only there to demonstrate the js. Instead of shaking, the .fas element turns red.

    $(document).ready(function() {

        $(".icon-hyperlink a").hover(function(e) {
                $(e.target).parents(".icon-hyperlink").find(".fas").addClass("fa-shake");
        }, function(e) {
                $(e.target).parents(".icon-hyperlink").find(".fas").removeClass("fa-shake");     
        });

  });
    .fa-shake {
  background: red;
}
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="icon-hyperlink">
        <span>
                <i class="fas fa-phone p-2">Icon</i>
        </span>
        <span>
                <a href="tel:XXXX XX XX XX">John: XXXX XX XX XX</a>
        </span>
</div>

    This can be achieved with no javascript and a little detective work of what FA uses behind the scenes.

    .phone::before{
  font-family: "Font Awesome 6 Free";
  content: "f095";
  display:inline-block;
  font-weight:900;
  color:black;
  margin-right:0.25em;  
}

.phone:hover::before{
  animation-name: fa-shake;
  animation-duration: var(--fa-animation-duration,1s);
  animation-iteration-count: var(--fa-animation-iteration-count,infinite);
  animation-timing-function: var(--fa-animation-timing,linear);
  animation-delay: var(--fa-animation-delay,0s);
  animation-direction: var(--fa-animation-direction,normal);
}
