tooltip loading image and executing function.

tooltip loading image and executing function.

Hello,

I am trying to load image and display other stuff dynamically, but I am having a hard time with it.

How can I find out "span class" on the code below?

what exactly defines "this"? and how can I access its contents?
 
<span class="PY4AAA">
<a title="" target="_blank" class="callsign" href="/qrz/PY4AQA">
<img src="/img/f/br.gif">&nbsp;PY4AAA</a>
</span>

$('span').tooltip({track:true,showURL:false,showBody: "*****",bodyHandler: function() {
                return this
} });
                        
Thank you!
