Performs an animation when the user begins to drag an object.

The following video demonstrates the drag animations:

Syntax

WinJS.UI.Animation.dragSourceStart(dragSource, affected).done( /* Your success and error handlers */ );

Parameters

dragSource
Type: Object

Element or elements being dragged.
affected [optional]
Type: Object

Element or elements whose position is affected by the movement of the dragged object. Typically, this is all other items in a reorderable list.

Return value

Type: Promise**

An object that completes when the animation is finished.

Remarks

The parameters of this function can be expressed in several ways:

As the special value "undefined", which means that the animation has no such target
As a single object
As a JavaScript array (possibly empty), in which each element of the array can be a single element or a JavaScript array of elements.
As a NodeList (for example, the result of querySelectorAll)
As an HTMLCollection

The position of the dragged item is normally updated through the CSS -ms-transform property. However, dragSourceStart overwrites that -ms-transform property. Therefore, to see expected behavior, you should wrap the dragged element in a second element which acts as a new parent. Apply dragSourceStart to the original element and -ms-transform to the new parent element.

Requirements

Minimum WinJS version	WinJS 1.0
Namespace	WinJS.UI.Animation
