函数api

1.setData

function (/** DataTransfer */dataTransfer, /** HTMLElement*/dragEl) {
	dataTransfer.setData('Text', dragEl.textContent); // `dataTransfer` object of HTML5 DragEvent
}

2. onChoose:

function (/**Event*/evt) {
	evt.oldIndex;  // element index within parent
}

3. onStart:

// Element dragging started

function (/**Event*/evt) {
	evt.oldIndex;  // element index within parent
}

4. onEnd:

// Element dragging ended
function (/**Event*/evt) {
	evt.oldIndex;  // element's old index within parent
	evt.newIndex;  // element's new index within parent
},

5. onAdd:

// Element is dropped into the list from another list
function (/**Event*/evt) {
	var itemEl = evt.item;  // dragged HTMLElement
	evt.from;  // previous list
	// + indexes from onEnd
},

6. onUpdate:

// Changed sorting within list
function (/**Event*/evt) {
	var itemEl = evt.item;  // dragged HTMLElement
	// + indexes from onEnd
},

7. onSort:

// Called by any change to the list (add / update / remove)
function (/**Event*/evt) {
	// same properties as onUpdate
},

8. onRemove:

// Element is removed from the list into another list
function (/**Event*/evt) {
	// same properties as onUpdate
},

9. onFilter:

// Attempt to drag a filtered element
function (/**Event*/evt) {
	var itemEl = evt.item;  // HTMLElement receiving the `mousedown|tapstart` event.
},

10. onMove:

// Event when you move an item in the list or between lists
function (/**Event*/evt, /**Event*/originalEvent) {
	// Example: http://jsbin.com/tuyafe/1/edit?js,output
	evt.dragged; // dragged HTMLElement
	evt.draggedRect; // TextRectangle {left, top, right и bottom}
	evt.related; // HTMLElement on which have guided
	evt.relatedRect; // TextRectangle
	originalEvent.clientY; // mouse position
	// return false; — for cancel
},

11. onClone:

// Called when creating a clone of element
function (/**Event*/evt) {
	var origEl = evt.item;
	var cloneEl = evt.clone;
}
