当我点击日期选择器中的日期时,我可以看到请求被发送到我的服务器,进行查询,返回结果集,但我的网格似乎没有刷新....?! ?!我一直在努力学习这个MVC模式框架工作,我无法相信学习曲线。似乎最简单的事情并不容易做到,当搜索网络时,有类似的帖子,但每一个都与我想做的有点不同,或者海报在不同的地方有代码或者他们没有使用MVC模式.....等等等等......等等
第一次访问我的服务器,用查询填充我的商店,因此网格成功 - 没有问题。此时,如果我从日期选择器中选择一个日期,则会对数据库进行调用,并使用我的JSON数据包发回请求 - 没问题。我验证了第一个请求中的JSON数据包与第二个和后续请求匹配,当使用chrome控制台和网络工具验证时,所有内容都在检查中。
非常感谢任何帮助。提前谢谢!

我刚刚快速提出了一个ExtJS 4.2 MVC应用程序的简单示例,该应用程序基于过滤器字段重新加载网格。 http://hutten.org/bill/extjs/2014/01/simple-extjs-42-mvc-example.html
