[javascript] jQuery: Get selected element tag name

Is there an easy way to get a tag name?

For example, if I am given $('a') into a function, I want to get 'a'.

You should NOT use jQuery('selector').attr("tagName").toLowerCase(), because it only works in older versions of Jquery.

You could use $('selector').prop("tagName").toLowerCase() if you're certain that you're using a version of jQuery thats >= version 1.6.

Note :

You may think that EVERYONE is using jQuery 1.10+ or something by now (January 2016), but unfortunately that isn't really the case. For example, many people today are still using Drupal 7, and every official release of Drupal 7 to this day includes jQuery 1.4.4 by default.

So if do not know for certain if your project will be using jQuery 1.6+, consider using one of the options that work for ALL versions of jQuery :

Option 1 :

jQuery('selector')[0].tagName.toLowerCase()

Option 2

jQuery('selector')[0].nodeName.toLowerCase()

This is yet another way:

$('selector')[0].tagName

You can use the DOM's nodeName property:

$(...)[0].nodeName

As of jQuery 1.6 you should now call prop:

$target.prop("tagName")

See http://api.jquery.com/prop/

nodeName will give you the tag name in uppercase, while localName will give you the lower case.

$("yourelement")[0].localName 

will give you : yourelement instead of YOURELEMENT

jQuery 1.6+

jQuery('selector').prop("tagName").toLowerCase()

Older versions

jQuery('selector').attr("tagName").toLowerCase()

toLowerCase() is not mandatory.
