extjs - 树的子节点/节点上的单击事件

Question

我真的被 ExtJs 树对象弄糊涂了，我的代码有问题，但我不知道是什么。

考虑我有这个代码:

var store = Ext.create('Ext.data.TreeStore', {
    root: {
        expanded: true,
        children: [
            { text: "detention", leaf: true },
            { text: "homework", expanded: true, children: [
                { text: "book report", leaf: true },
                { text: "alegrbra", leaf: true}
            ] },
            { text: "buy lottery tickets", leaf: true }
        ]
    }
});

Ext.create('Ext.tree.Panel', {
    title: 'Simple Tree',
    width: 200,
    height: 150,
    store: store,
    rootVisible: false,
    renderTo: Ext.getBody()
});

如何绑定(bind) 点击我的树的 child /叶子的事件？

像这样？

var store = Ext.create('Ext.data.TreeStore', {
    root: {
        expanded: true,
        children: [
            { text: "detention", leaf: true },
            { text: "homework", expanded: true, children: [
                { text: "book report", leaf: true },
                { text: "alegrbra", leaf: true}
            ] },
            { text: "buy lottery tickets", leaf: true }
        ]
    }
});

Ext.create('Ext.tree.Panel', {
    title: 'Simple Tree',
    width: 200,
    height: 150,
    store: store,
    rootVisible: false,
    renderTo: Ext.getBody(),
    listeners: {
        itemclick: function(s,r) {
                alert(r.data.text);
        }
    }
});
