How to extend jQuery to make it easier to retrieve the tagName

Question

I am looking to extend jQuery so I can easily retrieve the tagName of the first element in a jQuery object. This is what I have come up with, but it doesn\'t seem to work:

Answer 1

You may wish to add a toLowerCase() to make it more consistent (and XHTML compliant).

$.fn.tagName = function() {
    return this.get(0).tagName.toLowerCase();
}

alert($('#testElement').tagName());
