一个简单的Ext.XTemplate的实例代码

Ext.lib.Ajax.request( 
'POST', 
'/Index/mainIndex', 
{ success: function (data) { 
data.responseText = "{pros:" + data.responseText + "}"; //获取后台回调的省份城市JSON格式数据 
var response = Ext.util.JSON.decode(data.responseText); 
var province = new Ext.XTemplate( 
'<tpl for="pros">',//遍历读取pros 
'<p>{id}--{text}</p>', 
'<tpl for="children">',//遍历读取pros下的children 
'<p style="margin-left:10px;">{id}--{text}</p>', 
'</tpl>', 
'</tpl>' 
); 
province.compile(); 
province.append("Div2", response); 
} 
} 
);
