Creates an object that performs an animation that adds an item or items to a list.
The following video demonstrates both the create and delete animations:
Element or elements to add to the list.
Element or elements affected by the added items.
An object whose execute method is used to execute the animation. The execute method returns a Promise that completes when the animation is finished.
The parameters of this method 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 NodeList (for example, the result of querySelectorAll) (for example, the result of querySelectorAll)
- As an HTMLCollection
The general usage pattern for layout animations such as this function is as follows:
- Call the create function (such as the one discussed on this page) and save the result.
- Change the document layout as necessary to represent the new state. The items you add must be visible and have layout.
- Call the execute method on the object you saved in step 1 to perform the animation.
The following code shows an example.
// Step 1: Create the animation object and save the result var anim = WinJS.UI.Animation.createAddToListAnimation(added, affected); // Step 2: Insert the element given in the added parameter immediately before // the element given in the affected parameter. This causes both elements to move. affected.parentNode.insertBefore(added, affected); // Step 3: Execute the animation anim.execute();
