1) .get(0).tagName

Select an element that has a class name of “classTag1″, and use the .get(0).tagName function to display its tag name.

$('.classTag1').get(0).tagName;

2) .[0].tagName

2. Select an element that has a class name of “classTag1″, and use the .[0].tagName function to display its tag name.

$('.classTag1')[0].tagName;
