The function toggleClass simply introduces the attribute 'class' to the HTML element, not the actual class itself

I am facing a strange issue. I have previously used toggleClass and it worked perfectly fine. However, now only the 'class' attribute is being added to the element without actually adding the class itself. Here is an example:

$("#slideButtonMenu").click(function(){
  $("#sidebar").toggleClass("slidingLeft");
});

.slidingLeft {
  left: -220px;
}

When inspecting the element, this is what I see before clicking "#slideButtonMenu":

<aside id="sidebar"> == $0

After clicking the button:

<aside id="sidebar" class> == $0

The desired outcome after the first click is:

<aside id="sidebar" class="slidingLeft"> == $0

I'm not sure what == $0 means, but I don't think it impacts this issue. If I change toggleClass to addClass, it does add the class successfully... but then I can't slide the menu back out afterwards.

Answer №1

After receiving suggestions from @Rory McCrossan and @Turnip, I realized my click event was bound incorrectly.

The solution was to incorporate unbind(), as shown below:

$("#slideButtonMenu").unbind().click(function(){
    $("#sidebar").toggleClass("slideLeft");
});

It's functioning properly now!

UPDATE: As per @Turnip, adding unbind() may not have been necessary if my code had been executed correctly. Nevertheless, I'll stick with it for my proof of concept tomorrow.

UPDATE2: I've identified the errors. I accidentally loaded this script twice:

$("#slideButtonMenu").click(function(){
    $("#sidebar").toggleClass("slideLeft");
});

Once I corrected that to only load once, it worked without needing .unbind()
