If the parent class in HTML has a class of "active," then use jQuery to

I have attempted this, but unfortunately did not achieve the desired result. I am just brainstorming my ideas here.

HTML

<html>
  <div>
    <div class="spinner">
    </div>
  </div>
</html>

Jquery

if (".spinner"){
this.parent.addClass()
}
else {
this.parent.removeClass() }

My goal is to have CSS styling added to the parent class of the spinner when the spinner class is present in the HTML code. If the spinner class is removed from the HTML, the style added to the spinner's parent class should also be removed. How can I accomplish this?

Thank you for your advice.

Answer №1

There are a couple of things to address here.

To begin with, make sure your div is labeled with the class of "loader", as shown below:

<div class="loader">

Next, update your jQuery code to target $(this) (the jQuery object) instead of just this (the JavaScript object), like this:

if (!$(this).hasClass("loader")) {
    $(this).addClass("loader");
}
else {
    $(this).removeClass("loader"); 
}

Answer №2

HTML:

<div>
<div class="spinner">
</div>

Function:

function modifyParentWithSpinner(){
    var reference = $(".spinner"),
    classToAdd = "hello";

    if(reference.length > 0){
      // Element(s) with class 'spinner' are present
      reference.parent().addClass(classToAdd);
    }else{
      // Element(s) with class 'spinner' are not present
      reference.parent().removeClass(classToAdd);
    }
}

Call the function to update the parent element whenever necessary:

modifyParentWithSpinner();

Answer №3

Give this a shot...

let spContainer = $(".spinner");
if (spDiv){
    spContainer.parent().addClass("spinner");
}else {
    spContainer.parent().removeClass("spinner"); 
}
