asp.net - How can I determine the element type of a matched element in jQuery?

Question

I'm matching ASP.Net generated elements by ID name, but I have some elements which may render as text boxes or labels depending on the page context. I need to figure out whether the match is to a textbox or label in order to know whether to get the contents by val() or by html().

$("[id$=" + endOfIdToMatch + "]").each(function () {
    //determine whether $(this) is a textbox or label
    //do stuff
});

I found a solution that doesn't work, it just returns "undefined":

$("[id$=" + endOfIdToMatch + "]").each(function () {
    alert($(this).tagName);
});

What am I missing?

Just one jQuery too much:

$("[id$=" + endOfIdToMatch + "]").each(function () {
    alert(this.tagName);
});
