这个EXT 2.0 的例子 讲的是怎么样用aspserver和ext2.0构建弹窗效果! 服务器部分: var _http = new XMLHttp() ; var _return = _http.get("http://rss.sina.com.cn/news/china/focus15.xml") ; Write.writeXML(_return) ; 网页部分: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>新闻列表示例</title> <link type="text/css" rel="stylesheet" href="js/ext/resources/css/ext-all.css"/> <script type="text/javascript" src="js/ext/adapter/ext/ext-base.js"> </script> <script type="text/javascript" src="js/ext/ext-all.js"> </script> <script type="text/javascript" src="js/ext/source/locale/ext-lang-zh_CN.js"> </script> <script type="text/javascript" src="js/demo.js"> </script> </head> <body> <div id="example_grid"></div> </body> </html> JS部分: Ext.BLANK_IMAGE_URL = 'js/ext/resources/images/default/s.gif'; /********************************************************************************/ Ext.namespace("Ext.dojoChina.demo") ; Ext.dojoChina.demo.NewsWindow = function(_record){ var _me = this ; Ext.dojoChina.demo.NewsWindow.superclass.constructor.call(this, { title:_record.get("title"), width: 500, height:300, resizable:false, layout: "fit", plain:true, bodyStyle:"padding:5px;", buttonAlign:"right", buttons: [{ text:"查看详细", handler:function(){ window.open(_record.get("link")) ; _me.close() ; } },{ text: "关 闭", handler:function(){ _me.close() ; } }], items:{ html:_record.get("description") } }); } Ext.extend(Ext.dojoChina.demo.NewsWindow , Ext.Window) ; /********************************************************************************/ Ext.onReady(function(){ var _grid = new Ext.grid.GridPanel({ ds: new Ext.data.Store({ proxy: new Ext.data.HttpProxy({ url: "../app/demo.asp" }), reader: new Ext.data.XmlReader({ record: "item" }, [ {name: "title", mapping: "title"}, {name: "datetime", mapping: "pubDate"}, {name:"link" , mapping:"link"}, {name:"description" , mapping:"description"} ]) }), cm: new Ext.grid.ColumnModel([ {header: "新闻名称", width: 300, dataIndex: "title"}, {header: "新闻发布时间", width: 130, dataIndex: "datetime" , renderer: function(_value){ var _date = new Date(_value) ; return _date.format("Y-m-d H:i:s"); }} ]), sm: new Ext.grid.RowSelectionModel({singleSelect:true}), renderTo:"example_grid", width:500, height:300, loadMask: true }); _grid.getStore().load(); _grid.on("rowdblclick" , function(_grid){ var _record = _grid.getSelectionModel().getSelected() ; var _window = new Ext.dojoChina.demo.NewsWindow(_record) ; _window.show() ; }) ; }) ; 和前几例 最显著的差别还是js部分: 相同的部分都是采用同一框架!这样的好处是? 源代码下载:见www.dojochina.com 请批评指正! 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
