javascript - 在 Ext.button.Split 按钮中显示所选值

Question

从这个例子来看，即，

 Ext.create('Ext.button.Split', {
    renderTo: Ext.getBody(),
    text: 'Options',
    // handle a click on the button itself
    handler: function() {
        alert("The button was clicked");
    },
    menu: new Ext.menu.Menu({
        items: [
            // these will render as dropdown menu items when the arrow is clicked:
            {text: 'Item 1', handler: function(){ alert("Item 1 clicked"); }},
            {text: 'Item 2', handler: function(){ alert("Item 2 clicked"); }}
        ]
    })
});

如何动态显示按钮中的选择？谢谢!
