How to check if parent contains in html using javascript

Question

I need to check if the parent is a span. How can I do this using javascript (not jquery)?

Answer 1

element.parentNode.tagName.toLowerCase() == 'span' 

Answer 2

 var elem = document.getElementById("myElement"), isParentSpan = elem.parentNode.tagName === "span"; alert( isParentSpan ); 

Answer 3

Remember that .nodeName returns the UPPERCASE string (with some exceptions). It is safe for toLowerCase () when you are comparing.

 var el = document.getElementById('test'), parent = el.parentElement || el.parentNode, parentType = el.parentElement.nodeName.toLowerCase(); if ( 'span' === parentType ) { alert('Parent is a span!'); }
