最终的效果如下图所描述
上述效果的实现过程如下所示
直接上代码
如上图所示，我们点击treePanel触发tabPanel的变化，因此肯定是treePanel中添加了事件响应的代码
没错，就是这个
它的具体代码如下
//鼠标点击treePanel的item，然后触发tabPanel新增tab，所以必须首先获取tabPanel的对象
var tab = Ext.getCmp("centerPanelId");
//判断被点击的treePanel的item的类型，是否为leaf
if (record.get('leaf')) {
//获取treePanel的item的id(也就是菜单的唯一标识)
var id = record.get('id');
var text = record.get('text');
if (Ext.getCmp(id)){
//如果这个tab已经被添加过一次就不再添加第二次
//Ext.Msg.alert("已经有");
tab.setActiveTab(id);
}else{
//如果只是第一次被添加，那就把新的panel添加到tabPanel中去
var newTab = null;
newTab = Ext.create("Ext.panel.Panel",{
id:id,
autoDestroy:true,
title:text,
closable:true
});
var rTab = tab.add(newTab);
tab.setActiveTab(rTab);
}
}我们说的再具体一点，主页面是一个viewport，其中包括左侧一个treepanel右侧一个tabPanel
点击treepanel的leaf后，会触发右侧tabPanel添加相应数据信息的tab
当然，前提是我们事先使用store为viewport主页提供了treePanel的数据。
下面公布所有代码
viewport的代码
Ext.define('MyApp.view.MainVP', {
extend: 'Ext.container.Viewport',
alias: 'widget.mainvp',
requires: [
'Ext.toolbar.Toolbar',
'Ext.tree.Panel',
'Ext.tree.View',
'Ext.tab.Panel',
'Ext.tab.Tab'
],
layout: 'border',
initComponent: function() {
var me = this;
Ext.applyIf(me, {

}
]
},
{

id: 'leftAgentTreeId',
itemId: 'leftAgentTree',

collapsible: true,

viewConfig: {
itemId: 'leftAgentTreeView'
},
listeners: {
itemclick: {
fn: me.agentTreeItemClick,
scope: me
}
}
},
{
xtype: 'treepanel',
region: 'west',
split: false,
frame: true,
hidden: true,
itemId: 'leftOrgTree',
width: 180,

},
{

activeTab: 0,
items: [
{
xtype: 'panel',

}
]
}
]
});
me.callParent(arguments);
},
agentTreeItemClick: function(dataview, record, item, index, e, eOpts) {
/*
var rid = "uselessStr";
rid = record.raw.id;
if (rid.indexOf("agent") != -1){
//包含agent字符串，所以什么也不做
//Ext.Msg.alert("菜单信息","record.raw.id:"+record.raw.id+" record.raw.text:"+record.raw.text);
}else{
//不包含agent字符串，所以显示
Ext.Msg.alert("菜单信息","record.raw.id:"+record.raw.id+" record.raw.text:"+record.raw.text+" record.raw.leaf:"+record.raw.leaf);
}
// dataview.getItemId()显示treePanel拥有的view的itemid
*/
/*
下面是比较好一点的代码
var bsign = record.raw.leaf;
if(bsign===true){
var n = Ext.getCmp("barneyId").getItemId();
//var n = true;
Ext.Msg.alert("测试leaf","record.raw.id:"+record.raw.id+" record.raw.text:"+record.raw.text+" record.raw.leaf:"+record.raw.leaf+"++"+n);
}
*/
//下面这句很显然写错了因为leftAgentTreeId是treePanel的id，而不是我们应该获取的tabPanel的id
//var tab = Ext.getCmp("leftAgentTreeId");
//鼠标点击treePanel的item，然后触发tabPanel新增tab，所以必须首先获取tabPanel的对象
var tab = Ext.getCmp("centerPanelId");
//判断被点击的treePanel的item的类型，是否为leaf
if (record.get('leaf')) {
//获取treePanel的item的id(也就是菜单的唯一标识)
var id = record.get('id');
var text = record.get('text');
if (Ext.getCmp(id)){
//如果这个tab已经被添加过一次就不再添加第二次
//Ext.Msg.alert("已经有");
tab.setActiveTab(id);
}else{
//如果只是第一次被添加，那就把新的panel添加到tabPanel中去
var newTab = null;
newTab = Ext.create("Ext.panel.Panel",{
id:id,
autoDestroy:true,
title:text,
closable:true
});
//Ext.Msg.alert("Note","没有这个tab ++ ");
var rTab = tab.add(newTab);
//Ext.Msg.alert("Note","rTab.id "+rTab.getId()+" rTab.title "+rTab.title+" tab.id "+tab.getId()+" tab.title "+tab.title);
tab.setActiveTab(rTab);
}
}
}
});然后是store的代码
Ext.define('MyApp.store.LeftAgentStore', {
extend: 'Ext.data.TreeStore',
requires: [
'Ext.data.Field'
],
constructor: function(cfg) {
var me = this;
cfg = cfg || {};
me.callParent([Ext.apply({
storeId: 'LeftAgentStore',
root: {
text: '代理店',
id: 'agent-root',
expanded: true,
children: [
{
text: '北京代理店',
id: 'agent-bj',
expanded: true,
children: [
{
text: '详细信息',
id: 'detailInfo-bj',
leaf: true
},
{
text: '团队',
id: 'groupInfo-bj',
leaf: true
},
{
text: '文件夹',
id: 'folderInfo-bj',
leaf: true
}
]
},
{
text: '上海代理店',
id: 'agent-sh',
expanded: true,
children: [
{
text: '详细信息',
id: 'detailInfo-sh',
leaf: true
},
{
text: '团队',
id: 'groupInfo-sh',
leaf: true
},
{
text: '文件夹',
id: 'folderInfo-sh',
leaf: true
}
]
}
]
},
fields: [
{
name: 'text'
}
]
}, cfg)]);
}
});下面我们对上述代码进行完善，效果如下图所示：
也就是说，当我们点击不同的treePanel的leaf的时候，在center位置显示不同结构的panel
首先创建不同的view，也就是panel，如下图所示
分别对应显示详细信息、团队、文件夹这三部分信息
那么怎么在viewport中调用这三个panel呢？
也就是在主页面中调用其它页面，加载进来呢？
首先我们刚刚创建的三个panel要先起一个alias也就是别名
这样方便我们在viewport中使用js代码去创建它
然后
我们查看viewport中的代码，毕竟只是前端代码，数据就造假了
var tab = Ext.getCmp("centerPanelId");
//判断被点击的treePanel的item的类型，是否为leaf
if (record.get('leaf')) {
//获取treePanel的item的id(也就是菜单的唯一标识)
var id = record.get('id');
var text = record.get('text');
if (Ext.getCmp(id)){
//如果这个tab已经被添加过一次就不再添加第二次
//Ext.Msg.alert("已经有");
tab.setActiveTab(id);
}else{
//如果只是第一次被添加，那就把新的panel添加到tabPanel中去
var newTab = null;
if(id==="detailInfo-bj"){
newTab = Ext.create("widget.bjdetailpanel");
}else if(id==="groupInfo-bj"){
newTab = Ext.create("widget.bjgrouppanel");
}else if(id==="folderInfo-bj"){
newTab = Ext.create("widget.bjfolderpanel");
}
var rTab = tab.add(newTab);
tab.setActiveTab(rTab);
}我们依据treePanel的item的id进行判断，如果是第一次遇到这个tree叶子的被点击，我们创建对应内容的component
Ext.create("别名");
于是我们将所有代码改变一下
