How can I extract the className from a span that is selected using javascript?

I have this HTML:

<span class="redColor">gold</span>

And when I have the text selected that is within the span tags, I need to be able to somehow extract the className from the span using javascript. I don't know anything about the class in advance, only that it will be in a span, and the text will be selected.

I assume you mean Text selected with the mouse or the keyboard? You can access that with

window.getSelection()

Then you can work your way up the DOM tree:

window.getSelection().anchorNode.parentNode.className

See https://developer.mozilla.org/en-US/docs/Web/API/Selection.anchorNode for documentation of the Selection class

Use className property.

Example:

var x = document.getElementsByTagName('span');
document.write("Body CSS class: " + x.className);
