In jquery sortable UI,What can we get from the event function's parameters like ui and event?

I know we can get the current dragged element's id by ui.item.attr('id')

but what can we get from event parameter? 开发者_开发问答Could it like javascript, have event.target property?

or get anything else?

All callbacks receive two arguments: The original browser event and a prepared ui object, view below (if you name your second argument 'ui'), you can do:

ui.helper - the current helper element (most often a clone of the item)
ui.position - current position of the helper
ui.offset - current absolute position of the helper
ui.item - the current dragged element
ui.placeholder - the placeholder (if you defined one)
ui.sender - the sortable where the item comes from (only exists if you move from one connected list to another)

You can also get this info from the UI documentation. http://jqueryui.com/demos/sortable/

Inspect the object in Firebug or Chrome's Dev tools to see what information it provides.

Here's what I get in the stop event:

And if you expand the originalEvent: a.Event node, there's the target that you are looking for: target: HTMLTableCellElement
