jQuery SVG Class Manipulation: Why Do `addClass()` and `removeClass()` Fail?

jQuery SVG: Why Can't I Manipulate Classes?

When working with jQuery to manipulate SVG elements, you might encounter difficulties adding or removing classes. This is not a syntax error but stems from limitations within jQuery.

jQuery Limitations

jQuery versions prior to 3 have known limitations in interacting with SVG elements. Specifically, the .addClass() and .removeClass() methods may not function as intended.

Workaround Using .attr()

One workaround within jQuery is to use the .attr() method:

// Adding a class
$("#item").attr("class", "oldclass newclass");

// Removing a class
$("#item").attr("class", "oldclass");

Vanilla JavaScript Alternative

For a non-jQuery solution, you can utilize the element.classList.add() and element.classList.remove() methods:

// Adding a class
var element = document.getElementById("item");
element.setAttribute("class", "oldclass newclass");

// Removing a class
element.setAttribute("class", "oldclass");
