把省份与城市以树的形式输出

复制代码 代码如下:

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>{id}--{text}</p>',

'</tpl>',

'</tpl>'

);

province.compile();

province.append("Div2", response);

}

}

);
