Why Doesn\'t jQuery Add Classes to SVG Elements Reliably?

jQuery SVG: Limitations with Class Modifications

When attempting to manipulate classes on SVG elements using jQuery, you might encounter difficulties. Let's explore the issue.

In your provided code, you're attempting to add a "clicked" class to the SVG rectangle using .addClass(). However, this method may not function correctly due to an underlying limitation in jQuery.

JQuery versions prior to 3 have known issues when interacting with SVG elements. Specifically, they cannot reliably add or remove classes from SVG elements. This is because jQuery primarily manipulates the underlying HTML DOM, and SVG elements have a different internal representation.

Workarounds:

To overcome this limitation, you can employ the following workarounds:

• Upgrade to jQuery 3: Version 3 of jQuery addresses the issue with SVG class manipulation. If possible, update to this version to resolve the problem.
• Use Vanilla JavaScript: In modern browsers, you can directly access the classList property of the element and modify it. For example:

const element = document.getElementById("p5");
element.classList.add("clicked");

• Use jQuery's .attr(): You can use .attr() to manipulate the class attribute. However, remember that this changes the entire class list, rather than just adding or removing individual classes.

$("#p5").attr("class", "jimmy clicked");

By implementing these workarounds, you should be able to effectively add and remove classes from SVG elements using jQuery or vanilla JavaScript.
