Ajax drag-and-drop issue

Rails

Hey there.

I’m doing something similiar to the demo shopping cart at
(http://demo.script.aculo.us/shop), but with some differences. When you
drag an item to the div, it doesn’t return to the original location, as
you can only drag one of each item. Also I don’t want to have a separate
container to drag deleted items to, so I have a remove link under each
item. I think the significant difference though, is the fact that my
draggable is a div, with text and an image, and not just an image like
the script.aculo.us demo.

When a user clicks remove, this RJS template is called:

page.visual_effect :squish, “item-#{@item.id}”, :duration => 0.6
page.insert_html :bottom, :items, :partial => ‘item_display’

To show the original item for further dragging. Here’s where the problem
comes in:

I can subsequently drag the item back in FireFox, but not in Safari or
IE. The item just isn’t draggable even though my _item_display partial
is the same thing that was rendered when the page loaded, and dragging
worked then no problem. Also, just so you know, items is a div element
that the item is inserted into.

If I refresh the page, all is well.

Anyone run into this?

Thanks!

I figured it out. The element isn’t actually getting destroyed from the
page. So instead of reinserting a new element, you should just show the
element that was hidden when dragging.
