XML网格(XML Grid)

Posted 周三, 04/30/2008 - 09:46 by admin


前一节跟大家介绍了 基本数组网格(Basic Array Grid)以javascript数组的方式绑定的，在实际的开发应用中，很多情况数据源是xml格式的，那么ExtJs框架有没有提供xml格式的绑定的？答案是： 有

演示(demo)地址在文章最后.

效果图如下:

用到的有三个文件sheldon.xml、xml-grid.html和xml-grid.js。如果没有特别声明，.html跟.js文件名是一样的。

我用的EXTJS2.2的版本，按照上面的例子写的，怎么还是没数据显示呢？

by 游客 - 05/23/2009 - 20:17


问题如题，测试结果只显示了表格的表头，没有显示数据。请问这是什么原因呢？
代码如下：
Ext.onReady(function(){
var reader1 = new Ext.data.XmlReader({ record: 'Item', id: 'ASIN' },
[ {name:'Author', mapping: 'ItemAttributes>Author'},
'Title', 'Manufacturer', 'ProductGroup']
) ;

/*定义数据源*/
var dataStore = new Ext.data.Store({
url: 'NewFile.xml',
// data:data1,
reader: reader1,
autoLoad:true
});
var colModel = new Ext.grid.ColumnModel([
{header: "Author", width: 120, dataIndex: 'Author'},
{header: "Title", width: 180, dataIndex: 'Title'},
{header: "Manufacturer", width: 115, dataIndex: 'Manufacturer'},
{header: "Product Group", width: 100, dataIndex: 'ProductGroup'}
]);

var grid = new Ext.grid.GridPanel({ ds: dataStore, cm: colModel});
grid.render(document.body);
dataStore.load();

});

xml拒绝访问

by 游客 - 05/05/2009 - 15:31

在本机打开\ext-2.0.2\examples\grid\xml-grid.html。 提示运行时错误，拒绝访问。哪位达人知道原因？？

需要服务器环境支持

by admin - 05/07/2009 - 09:31

由于安装原因本地访问html是会报错的.
使用 http://xxx/xxx/xml-grid.html

看了半天程序都不懂

by 游客 - 07/05/2008 - 13:58

看了半天程序都不懂，原来这个xml和程序差了十万八千里。请楼主更正，要记得仔细检查啊。
真正的xml地址在 http://extjs.org.cn/extjs/examples/grid/sheldon.xml
