Vanilla JavaScript .closest without jQuery

Question

I\'m working on an application that only has jQuery 1.1 installed which dosn\'t support the .closest method.

My script currently looks like this:

$(\         


        

Answer 1

myImage.parentNode;

Is as vanilla as it gets. Whack that in a loop until you hit the required tag type:

while(thisTag.parentNode.tagName !== 'TD') // uppercase in HTML, lower in XML
    {
     thisTag=thisTag.parentNode;
    }

That should do the trick in plain old js.
