Rails spinoffs - May 2007 - Any tips for slow drag and drop in IE (or any other browser for that matter)

Hiya,

I have just recently began to use Script.aculo.us.
It is awesome!!!

1) I have noticed that when I created a DIV Shortable with let say 10+
children in it that IE drags are very slow, while Firefox is fast. Any
Idea on how I can speed this up?

2) Also as a second parter are there any tips on making the slide/
blind effects not warp the divs inner spacing when its sliding/
blinding in IE?

3) Random question:
Is Scriptaculous only developed by Thomas Fuchs?
If so "WOW", secondly that would explain the almost complete lack of
documentation. (the documentation section should be renamed loosly
scatter examples, most of which are in "Ruby helpers" or outdated).

4) The FAQ on the Script.aculo.us site leads to a ''This page cannot be
displayed'' error.

Have you tried 1.7.1 beta 3? If so, do you have an example of this  
online somewhere so we can take a look?

I guess the bulk of the code was developed by me, but there are loads  
and loads and loads of contributors.

Thanks.

The quality of the documentation in the wiki is very low, I know.  
Please help updating it (hey, it''s a wiki!), though currently the  
wiki seems to be down, that''s the reason why the FAQ is not working,  
too. I''ve no idea when it will be available again (stikipad seems to  
have a major upgrade going on: http://www.stikipad.com/buzz/2007/05/ 
scheduled_maintenance_may_30th/).

Best,
Thomas

Hello Thomas,

Thanks for the reply.

Yes it is 1.7.1beta3, but unfortunately I am not able to publish an
example online.
I was just wondering if other users have had similar problems and
found ways around it.

I do have a very limited example of a blog I am working on getting up
(when ever I have free time).
It shows the div warping issue in IE 6.
http://www.protolific.net/

Keep in mind the blog framework is running in debug mode.
This means no script concatenation/gzipping or server-side caching.
It''s just the default blog splash for now.

Click on the "Portlets" to collapse them.
You will see the content jump around in IE6.
There is no css change/indicator for a closed Portlet vs an open on
yet either.

When/while I get this blog up I would love to help contribute toward
documentation.

I have the same problem. Maybe I have a litte too much load burdened
on scriptaculous.

My application has two sortable/dropable lists with nearly 150
elements in unordered lists. The elements (li) contain a small table
with an in-place-edit field and are reloaded from the server on
selection of some other fields.

On Firefox it is fast and usable, in IE I have to wait 5 seconds to
get the lists on screen. IE seems to be very busy on this, my progress
indicator (a animated gif) stops the animation.

Even worse I found, that the selection of a draggable element does not
work on a slower computer, e.g. my laptop on battery power. When I try
to select e element, I can only select the displayed text. This effect
is worse in IE7 than IE6.

Do you use handles?

If so, try the new handles option in Sortable.create, which takes an  
array of elements or element ids (of your handles) to speed up  
initializing.

Basically you can now do:

Sortable.create(''sortable_elements_handles'',{
   handle: ''handle'',
   handles:  
[''h_1'',''h_2'',''h_3'',''h_4'',''h_5'',''h_6'',''h_7'',''h_8'',''h_9'',''h_10''],
});

See test/functional/sortable_test.html (lower half) for more usage  
information.

Best,
Thomas

Hi Thomas,

sorry about my long delay.

The slow init is one point. But much worse is the effect, that the
sortables do not react on a click. When I try to move a element from
one list to another, I am not able to pick up a element and drag it.
The only reaction ist the selection of text.

My sortables contain consists of 2 lists (<ul>) with about 100-150
listelements together. The elements themself are small tables with 2
rows/3 columns.

Do you know a upper limit of elements in sortables with drag&drop
between different lists?

Ernst

Ernst, do you have a margin between your sortables?
I was having the select problem but it actually occurred when i clicked in
the margin instead of on the sortable

Gareth, I finally found my error.

I have two lists which are filled with an Ajax.Updater() each. The
second Ajax.Updater has a onComplete:function() which calls
Sortable.create("first list") and Sortable.create("second
list").

Since the AjaxUpdater() worked asynchronous, I had situations when the
second Ajax.Updater() finished before the first one. This means it''s
onComplete function tried to Sortable.create() something, which was
not ready.

I wanted to do all the work in one onComplete() function, because I
have to calculate sums over elements in both sortables.

I changed the first Ajax.Updater() to Ajax.Updater( ... asynchronous:
false, ...) and it works in IE6 and IE7.

Thank you for your support.
