finding the type of an element using jQuery

In jQuery, if I have a reference to an element, how can I determine what kind of element it is, for example, an input or an dropdown? Is there any way to find out?

The following will return true if the element is an input:

$("#elementId").is("input") 

or you can use the following to get the name of the tag:

$("#elementId").get(0).tagName

You can use .prop() with tagName as the name of the property that you want to get:

$("#elementId").prop('tagName'); 

It is worth noting that @Marius's second answer could be used as pure Javascript solution.

document.getElementById('elementId').tagName
