We have an application that opens sections (div) of a webpage and
fills it with the content of an AJAX response by the server.
It all worked fine with IE6 and FF3 until we upgraded to JQuery 1.3.2
(were using 1.3 before). It still worked in IE6, but FF couldn't close
the section (slideUp) anymore.
This is the code of the AJAX-request: the div is "opened" and its
content is shown. This did work in 1.3 and still does in 1.3.2 for
both FF and IE6:
$.post(sectionAction, function(data){
$("#content").html(data);
$("#content").slideDown("slow");
});
Because we do only issue a request the first time a user opens a
section, the visibility of the content div is afterwards triggered via
slideUp/slideDown. Here's the code:
if ($("#content").is(":hidden")) {
$("#content").slideDown("slow");
} else {
$("#content").slideUp("slow");
}
All of the above worked perfectly until we upgraded to 1.3.2. The
effect in FF was that you could see the div close smoothly but pop
open again after being closed.
Debugging with some JS alerts and Firebug, we found out that the check
for :hidden in the if above didn't return the right status of the div
and therefore always entered the first branch of the if.
A second effect was that once we changed the is(:hidden) check to css
("display") == "none", the second branch of the if was executed, but
now slideUp didn't do anything to the div.
As we read in the release notes, a change to :hidden was made in
1.3.2, which should not be a problem. It looks like slideUp/slideDown
are not "updated" in 1.3.2 according to the new logic.
We now downgraded to JQuery 1.3 again.
Thanks,
Andy
