Retreiving Coordinates of Elements On A Page

[Ian Davies]

I think javascript ans CSS is the solution for my problem. I wish to use
them to retreive the relative coordinates of an element on webpage and store
it in an text field on pressing a button. or preferably have the text boxes
continuously update with the coordinates as a I drag the elements around. I
have borrowed some code to move the elements but Im new to javascript and
need a few pointers or links to something along these lines.

Please check out my test page to see what I need to do and what Ive done so
far

If you want to learn about element position, read here:

The script is junk, some extracts below:

<script language="JavaScript1.2">

That may have serious repercussions in some browsers in certain
circumstances:

Ditch the language attribute completely and use the required type attribute:

<script type="text/javascript">

[...]

function drags(){
if (!document.all)
return

[...]

That test makes your script dependent on support for a very old,
proprietary and deprecated method, resulting in your script not working
in perhaps 30% of web browsers.

There are numerous other examples of very bad coding style, e.g.

document.onmouseup=new Function("dragapproved=false")
