iview中tree的事件运用

iview中的事件和方法如下:

test.json 文件
{children:[
{id:'01',text:'a01',children:[
{id:'01-01',text:'a01-01',leaf:true},
{id:'01-02',text:'a01-02',children:[
{id:'01-02-01',text:'b01-02-01',leaf:true},
{id:'01-02-02',text:'a01-02-02',leaf:true}
]},
{id:'01-03',text:'b01-03',leaf:true}
]},
{id:'02',text:'b02',leaf:true}
]}

//--------------------------------------定义上边 top窗体----------------------------
var north=new Ext.Panel({
                        title: 'north',
                        region: 'north',
                        split: true,
                        border: true,
                        collapsible: true,
                        height: 80,
                        minSize: 100,
                        maxSize: 120
    });

 

//--------------------------------------定义右边 east窗体----------------------------
var east=new Ext.Panel({
                        title: 'east',
                        region: 'east',
                        split: true,
                        border: true,
                        collapsible: true,
                        width: 100,
                        minSize: 100,
