Determining Element Page Coordinates, Part 2
IE for Windows and TABLEs
In Part 1 of this series of articles, we
created JavaScript functions used to determine the page position of
HTML elements, positioned or static, that expose position information
about themselves.
In creating the functions, DL_GetElementLeft() and
DL_GetElementTop(), we took the opportunity to explore
parent-child element hierarchies in great detail. We ended up with
functions for IE for Windows and NS6+ that could retrieve the page position
of any element... more or less
With the present article, we will begin an attempt to reduce our margin
of error, by looking at browser quirks, rule exceptions and the like.
Those of you who have worked with our functions in your own
applications may have noticed that they do not always return the correct
values when calculating the page position of elements contained in
TABLEs. This is true of IE for Windows and later versions of
NS6+, although for completely different reasons.
We'll address the IE quirks in the present article.
It is highly recommended that you have a knowledge of the functions
created in Part 1, as we will be
expanding the same functions.
The in-page examples will be best appreciated when viewed with IE for
Windows as it is the browser under discussion. When viewed with NS6+,
for instance, the examples will work but won't give the required
result.
So, let's move on...
