1 建立get.php
get.php=>
复制代码 代码如下:
<?php
$data=array(
array(1,"yixing",123),
array(2,"chenlin",13),
array(3,"lixin",123),
array(4,"liumei",344),
array(5,"qiuye",343),
array(6,"zhangli",231),
array(7,"chenggong",1234),
array(9,"linmei",123),
array(10,"gaoxin",234),
array(11,"ximi",1234),
array(12,"suoming",1234)
);
echo json_encode($data);
?>
2 在下载的extjs中搜索到PagingMemoryProxy.js，与get.php放在一个文件夹中
3 建立文件grid.html
grid.html=>
复制代码 代码如下:

});
Ext.Ajax.request({ //读取后台传递于前台数据
url: 'get.php',
method:'get',
success:function(response, opts){
var obj= Ext.decode(response.responseText);//obj储存响应的数据
store.proxy = new Ext.data.PagingMemoryProxy(obj),//PagingMemoryProxy() 一次性读取数据
store.load({params:{start:0,limit:5}});//按5条记录分布
},
failure: function(){Ext.Msg.alert("failure");}
});

root.appendChild(user);
user.appendChild(user1);
user.appendChild(user2);
//建立根节点
var tree=new Ext.tree.TreePanel({
width:180,
height:300,
root:root
})
//中间区域
var tabPanel = new Ext.TabPanel({
region : 'center',
enableTabScroll : true,
activeTab :0,
margins:'5 5 5 5',
items : [{
id : 'homePage',
title : '首页',
autoScroll : true,

}]
});
function treeClick(){
tabPanel.add({
title:'用户',
id:'1',
activeTab:1,
closable:true,
autoLoad:{
url:'grid.html',
scripts:true
}
})
}
user1.on("click",treeClick);
//界面显示
new Ext.Viewport({

layout:'border',
items:[
{
region:'west',
layout:'fit',
width:200,

<body>
</body>
</html>
6 浏览器中输入http://localhost/register_01/r01/r01.php
7 总结
树形监听事件:tree.on
Ext.data.ArrayReader读取数组到一个元数据对象
复制代码 代码如下:
function(response, opts){
var obj= Ext.decode(response.responseText);//obj储存响应的数据
store.proxy = new Ext.data.PagingMemoryProxy(obj),//PagingMemoryProxy()一次性读取数据
store.load({params:{start:0,limit:5}});//按5条记录分布
}//分页基本应用
Ext.PagingToolbar基本应用
