1建立数据表
CREATE TABLE `login` (
`id` int(11) NOT NULL,
`name` varchar(20) NOT NULL,
`password` varchar(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
insert into login values
('1','hong','1234'),
('2','linxiang','1234'),
('3','chen','99a9s'),
('4','luxi','aabe2');
?2建立jsonreader.html视图文件，jsonreader.html调用json.js
<html>
<head>
<title>注册</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<link rel="stylesheet" type="text/css" href="/ext/resources/css/ext-all.css"/>
<script type="text/javascript" src="/ext/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="/ext/ext-all.js"></script>
<script type="text/javascript" src="json.js"></script>
</head>
<body>
<div id='grid'></div>
</body>
</html>
3json.js 构建extjs的界面，将界面与前台视图关联(id=grid) 动态数据与后台getData.php关联.关键所在
Ext.onReady(function() {
store=new Ext.data.JsonStore({
url:'getData.php',
data:[],
fields:[
{name:'id'},
{name:'name'},
{name:'password'}
]
});
store.load();
new Ext.grid.GridPanel({
store:store,
mode:'remote',
title:'简单Grid表格示例',
applyTo:'grid',
width:250,
height:150,
frame:true,
columns:[
{header:"id",width:50,dataIndex:'id',sortable:true},
{header:"姓名",width:80,dataIndex:'name',sortable:true},
{header:"年龄",width:80,dataIndex:'password',sortable:true}
]
})
});
?4后台查询从数据库取数据
<?php
$conn = mysql_connect("localhost", "root", "*****");
mysql_select_db("test");
$sql = "select id,name,password from login";
$result = mysql_query($sql, $conn);
while ($row = mysql_fetch_array($result)) {
$arr4[] = $row;
}
echo json_encode($arr4);
?>
5运行http://localhost/jsonreader.html
关于引用ext的js,css报错问题Unknown: Failed opening required '/var/www/html/deploy/js.php'
删除ext目录下面的.htaccess文件
