Guidance on using dragend 'tree'

[alastairwalkerParticipant]

The documentation refers to:

jQuery(instanceSelector).jqxTree({dragEnd: function(item, dropItem, args, dropPosition, tree) {});

The documentation (and forum questions) provide little insight into how to use ‘tree’.

All I can find is the comment ‘ // tree – the jqxTree’s jQuery object associated to the dropItem. If the tree’s id is ‘tree’, this returns $(“#tree”).

If I however look at the tree object – the information is obscure i.e.

({0:{jQuery1112027691987898120807:315}, context:{jQuery1112027691987898120807:315}, length:1})

using .toSource() to look at the object.

Do you have any guidance / insight to offer on this?

Perhaps I can provide further context to my question.

Referring to the drag and drop demo:

http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxtree/index.htm#demos/jqxtree/dragdrop.htm

There are two possible modes of operation – drag and drop within a single tree, or drag and drop from one tree to the other.

After a drag operation is started, and the drop is performed, how does one determine which tree is the target?

Best regards,

Hello Alastair,

In the dragEnd callback function, tree is the jQuery object of the target tree. In the case of the demo, if you drag from treeB to itself, in dragEnd tree.attr('id') will be “treeB”, and if you drag from treeB to treeA – “treeA”.

A jQuery object is the result of a jQuery selection, e.g. $('#treeB').
