card布局解决复杂操作的布局问题

一直不是很待见直接使用card布局，直到对于一些稍微复杂点的业务，

通过border布局和弹窗体的方式解决特别费劲之后，才想起了card布局，

发现card布局真是一个很好的解决办法。

那个使用起来很简单，对于里面的每一个页签，我们都要设置好一个itemId,

这样就可以   setActiveItem( ) 方法来限制展现哪个卡片了。

对于card布局，只要知道用这个方法就足够了。

设置一下itemId属性。

        zhuUx.centerContainer = Ext.create('Ext.container.Container', {
                region: 'center',
                items: [zhuUx.luxianGrid, zhuUx.yinhuanLuduanGrid, zhuUx.editor],
                layout: 'card'
            });

            zhuUx.luxianNextAction = Ext.create('Ext.Action', {
                scope: zhuUx,
                tooltip: '下一步',
                scale: 'medium',
                handler: zhuUx.onLuxianNextAction,
                text: '下一步'
            });

            zhuUx.yinhuanLuduanNextAction = Ext.create('Ext.Action', {
                scope: zhuUx,

                scale: 'medium',
                handler: zhuUx.onYinhuanLuduanNextAction,
