reading style value

[Ward Germonpré]

Hi,
I know you can position an element using a style property like so :

element.style.left=200px;

But how can you READ an elements style.left property ?

I want to position:fixed the columnheaders in a scrollable table an intend
to use this strategy:

First I dynamically construct the table, and when it's attached to the
document, I want to read the coordinates of the columnheaders and then
'fix' them using a different classname that I set up with 'position fixed'
in my stylesheet.

Can this work ?

thx

Ward

No, it should be a string!

element.style.left='200px';

Only usefull if the element has an absolute/relative position, methinks.

But how can you READ an elements style.left property ?

alert( element.style.left );

Please show a scarce example code.

Creating cross-browser locked table header code is tricky. I prefer to
separate the IE world from the rest of the world, and use stuff like this:

It might provide a few ideas, at least ;)
