How to find the ID of the "current" element

Hello. A question.
It is possible to refer to the ID of an element within the element
itself? And, if yes, what is the instruction or function.

Example. Assume I have this:

<div id="Square1" onclick = "Clicked('Squar e1')"></div>

You see the ID of the element "Square1" also appears later on the
function invocation "Clicked('Squar e1')". My question is: can I replace
the second occurrence of "Square1" with an instruction indicating the
current ID element? How?
For instance, I assume the instruction existed and were
"CurrentElmID() ", I would have:

<div id="Square1" onclick = "Clicked(Curren tElmID())"></div>

Hope my question is clear. Thanks.

Although virtually the only useful thing that can be done with that ID
is to use it to look up a reference to the element in the DOM, and as -
this - is a reference to that element at the point when its - id -
property is read it would be more sensible to pass the reference on the
function called instead of a string ID.

Thanks Evertjan, very helpful.

Thanks Richard for the comments.
I need it because I prefer to have updatable code in one place only:
more maintenable.

I hope there are no browser compatibility issues with this one :).

Thank you very much.

"Going back to square1" should be an option.
