How to apply CSS on an element in innerHTML with jQuery?

Question

I am using CKEditor. I have the html in a textarea. I want to get that HTML. And want to apply a class on the body tag in that markup.

jQuery('#htmlData').val() gives me the HTML.

How can I apply a class in the body tag present in this val()? Do I need to use html()?

I need the selector for this.

Answer 1

jQuery(jQuery('#htmlData').val()).css('color','red');

Do you have a live example/demo?

Answer 2

This might work:

jQuery("body", jQuery('#htmlData').val()).addClass("something");
