Sencha Touch defferend方法类似于jQuery

Question

Sencha Touch是否有与jquery defferend类似的方法？

$.when(

  // Deferred object (probably Ajax request),

  // Deferred object (probably Ajax request),

  // Deferred object (probably Ajax request)

).then(function() {

  // All have been resolved (or rejected), do your thing

});

让我们说，等待3个商店加载并在之后做点什么？

这是我的示例代码：

Ext.getStore('Store1').load({ callback: createGrid });
Ext.getStore('Store2').load({ callback: createGrid });

var loadedStores = 0;
function createGrid() {
    loadedStores = loadedStores + 1;

    if (loadedStores === 2) {
        grid = Ext.create('Ext.grid.panel', {
            ...
        });
    )
}

不太好，但它有效且可扩展。
