基于ExtJS Grid创建Table例子

基本思路:

基于ExtJS4.1版本开发,主要是首先创建一个Data Model组件,mockup一些JSON数据

然后将data Model与JSON数据绑定到创建的data store中,最后创建grid组件同时绑定

之前的data store完成整个程序。


一个简单ExtJS组件结构图:


程序运行结果如下:


JavaScript部分的源代码如下:

Ext.require([
    'Ext.grid.*',
    'Ext.data.*',
    'Ext.util.*',
    'Ext.state.*'
]);

Ext.onReady(function() {
	// mock up data
	// sample static data for the store
    var myData = [
        ['gloomyfish',	31, 'M',  'software',  '09 July 1980'],
        ['Mike',	31, 'M',  'software',  '09 July 1984'],
        ['Green Mook',	31, 'M',  'software',  '09 July 1980'],
        ['Rose Kate',	25, 'F',  'software',  '09 July 1987'],
        ['Dave Wu',		28, 'M',  'software',  '24 July 1984'],
        ['Hong Naa',	31, 'M',  'software',  '09 July 1980']
    ];
    
    // create data model
    Ext.define('EmplyeeInfo', {
        extend: 'Ext.data.Model',
        fields: [
           {name: 'employee', type: 'string'},
           {name: 'age',      type: 'int'},
           {name: 'gentle',    type: 'string'},
           {name: 'department',  type: 'string'},
           {name: 'birthday', type: 'date', dateFormat: 'd F Y'}
        ],
    });
    
	// create the data store
    var store = Ext.create('Ext.data.ArrayStore', {
    	model: 'EmplyeeInfo',
        data: myData
    });
    
    // create the Grid
    var grid = Ext.create('Ext.grid.Panel', {
        store: store,
        columns: [
            {
                text     : 'Employee Name',
                flex     : 1,
                sortable : false,
                dataIndex: 'employee'
            },
            {
                text     : 'Age',
                width    : 75,
                sortable : true,
                dataIndex: 'age'
            },
            {
                text     : 'Gentle',
                width    : 75,
                sortable : true,
                dataIndex: 'gentle'
            },
            {
                text     : 'Department',
                width    : 75,
                sortable : true,
                dataIndex: 'department'
            },
            {
                text     : 'Birthday Date',
                width    : 85,
                sortable : true,
                renderer : Ext.util.Format.dateRenderer('m/d/Y'),
                dataIndex: 'birthday'
            }
        ],
        height: 350,
        width: 600,
        title: 'Employee Information Table',
        renderTo: 'grid-example',
        viewConfig: {
            stripeRows: true
        }
    });
});
HTML部分的源代码如下:

<html>
<head>
    <title>Hello Ext</title>
    <link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css">
    <script type="text/javascript" src="extjs/ext-all.js"></script>
    <!-- <script type="text/javascript" src="app.js"></script> -->
    <script type="text/javascript" src="app/grid-demo.js"></script>
    <style type="text/css">

			margin-top: 30px;
			margin-right: 30px;
			margin-bottom: 30px;
			margin-left: 30px;
		}
	</style>
</head>
<body>
