导读：1 建立get.php get.php=> 代码如下: $data=array( array(1,"yixing",123), array(2,"chenlin",13), array(3,"lixin", array(4,"liumei",344), array(5,"qiuye",343), array(6,"zhangli",231), array(7,"chenggong",1234), array(9,"linmei", array(10,"gaoxi

1 建立get.php

get.php=>

array(9,"linmei",
array(10,"gaoxin",234),
array(11,"ximi",
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=>

4 建立文件r01.js
r01.js=>

代码如下:

Ext.onReady(function() {
