What is the current element in Javascript?

How can I find out what the element is that a <script> sits in?

As an example, let's take this

<div>

 <script type=text/javascript>

  var time = new Date(), hrs = time.getHours(), min = time.getMinutes();

  document.write('It is '+hrs+:+(min<10?'0':'')+min);

 </script>

</div>

Then if I want to change this to something more modern, how can I find out what element we're in?

So I want to write, for instance in jQuery

$(thisdiv).html('It is '+hrs+:+(min<10?'0':'')+min);

but how do I get thisdiv?

Yes, I know, I can put an ID on it, but I have the feeling that wouldn't be necessary. The browser knows where we are, otherwise it couldn't even do the document.write!

So, suggestions? I searched, but couldn't find it. Is it so simple that I'm overlooking the obvious?

Script are executed in the order of appearance in the document. The contents of a script tag are evaluated on encounter, so, the last <script> element is always the current one.

Code:

<div>

  <script>

    var scriptTag = document.getElementsByTagName('script');

    scriptTag = scriptTag[scriptTag.length - 1];



    var parent = scriptTag.parentNode;

  </script>

</div>
