Hi,
I've created a UI where items can be dragged from a palette and
dropped into a table - using jQuery and iDrag/iDrop from Interface.
So, I've made every table cell and heading ('th.td') a Droppable,
so there could be hundreds of droppables, but only a small amount
of draggables (ie. less than 20).
Now this is causing a major delay on starting a drag operation.
I've had a look at idrop.js, and highlight() seems to where the
delay occurs. I tried to profile the code using venkman, but can't
my head round it at the minute - anyone know an easy way to profile
a javascript function?
Anyway, could anyone suggest an alternative, some performance
improvements, or where the bottleneck is in highlight()?
I thought about making the whole table a droppable - but I'm unsure
of how to retreive the target element from a draggable.
(BTW, i'm using ghosting if it makes a difference)
Cheers
- Mark Gibson
