Question

I have this:

var targetTitle = targetElement.getElementsByTagName('title').item(0);

Am i passing a plain string into targetTitle? or what am i passing exactly?

Which element would be item(1), item(2), etc… in here:

<title>title1</title>
<title><title2</title>

Does it just look for ALL the title tags on the page and return the 0,1,2/?

Would this return ‘title2’:

targetElement.getElementsByTagName(‘title’).item(1)

Answer 1

The targetTitle will contain a reference to the DOM element object for the title tag.

The code only gets the first title tag, as there is only one in each document.
