Looking at that code, two things jumped out at me, but it wasn''t
either of them. :-)
The third thing was more subtle: This line is missing from
showLink():
$(''area'').stopObserving(''mouseover'',
showLink);
Consequently, as the mouse is moved over the div, showLink is fired
repeatedly. I don''t know why, but that seems to muck things up in
IE. Adding the line above fixed it; and it also makes sense as you
don''t want to constantly repeat the logic in showLink.
FWIW, one of the things I noticed that _wasn''t_ the problem probably
still needs fixing: You''re inserting the toInsert span into the div
without removing it from its original location. I don''t think
that''s
ideal. Here''s how I would modify showLink:
* * * *
function showLink() {
var toInsert;
var area;
area = $(''area'');
area.stopObserving(''mouseover'', showLink);
toInsert = $(''toInsert'');
toInsert.remove();
area.insert(toInsert);
toInsert.show();
}
* * * *
The changes are:
1. stopObserving area so showLink doesn''t get repeated calls
2. Cache element references to a local variables rather than looking
them up repeatedly
3. Remove toInsert from its old location before inserting it elsewhere
4. Show it only once it''s in its new location
(The other of the two things I originally noticed was just me being
pessimistic about IE and didn''t turn out to be anything, so
don''t
worry about it.)
Hope this helps,
