兑现通用的CRUD之四――视图定义

?

接上篇（javaEYE的图片只能插三个？），继续发截图。

由于上文中我们已经总结出一个与数据库CRUD相对应的界面范式，那么进一步地，可以通过以下javascript代码，简单地给出必要的信息，

告诉ExtJS我们想获得怎样的界面。

相关代码如下：

BView.viewMap={
 "dao.hb.OStation":{
	req:{
		"pss" : [["id", "name","code","topology","tel", "longitude","latitude","status","tmCreate","tmModify","remark"]],

以上javascript代码遵循一个简单的视图定义规则，对规则简要描述如下：
