ExtJS 2.0 GridPanel基本表格简明教程(2)

var store=new Ext.data.JsonStore({data:data,fields:["id","name","organization","homepage"]});
var colM=new Ext.grid.ColumnModel([{header:"项目名称",dataIndex:"name",sortable:true},
{header:"开发团队",dataIndex:"organization",sortable:true},
{header:"网址",dataIndex:"homepage",renderer:showUrl}]);
var grid = new Ext.grid.GridPanel({
renderTo:"hello",
title:"中国Java开源产品及团队",
height:200,
width:600,
cm:colM,
store:store,
autoExpandColumn:2
});

上面的代码得到的结果与前面的一样。当然，表格同样能显示xml格式的数据，假如上面的数据存放成hello.xml文件中，内容如下：

复制代码 代码如下:

<?xml version="1.0" encoding="UTF-8"?><dataset> <row> <id>1</id> <name>EasyJWeb</name> <organization>EasyJF</organization> <homepage></homepage> </row> <row> <id>2</id> <name>jfox</name> <organization>huihoo</organization> <homepage></homepage> </row> <row> <id>3</id> <name>jdon</name> <organization>jdon</organization> <homepage>s.jb51.net</homepage> </row> <row> <id>4</id> <name>springside</name> <organization>springside</organization> <homepage>tools.jb51.net</homepage> </row> </dataset>

为了把这个xml数据用ExtJS的表格Grid进行显示，我们只需要把store部分的内容调整成如下的内容即可：

复制代码 代码如下:

var store=new Ext.data.Store({
url:"hello.xml",
reader:new Ext.data.XmlReader({
record:"row"},
["id","name","organization","homepage"])
});

其它的部分不用改变，完整的代码如下：

复制代码 代码如下:

function showUrl(value)
{
return "<a href='http://"+value+"' target='_blank'>"+value+"</a>";
}
Ext.onReady(function(){
var store=new Ext.data.Store({
url:"hello.xml",
reader:new Ext.data.XmlReader({
record:"row"},
["id","name","organization","homepage"])
});
var colM=new Ext.grid.ColumnModel([{header:"项目名称",dataIndex:"name",sortable:true},
{header:"开发团队",dataIndex:"organization",sortable:true},
{header:"网址",dataIndex:"homepage",renderer:showUrl}]);
var grid = new Ext.grid.GridPanel({
renderTo:"hello",
title:"中国Java开源产品及团队",
height:200,
width:600,
cm:colM,
store:store,
autoExpandColumn:2
});
store.load();
});

store.laod()是用来加载数据，执行上面的代码产生的表格与前面的完全一样。
