推荐答案

开箱即用4.1，否.

您将需要覆盖负责的 provider 代理，原因是当前仅提交属性值对( Ext.util.过滤器完全不支持任何比较器进行remotesort.因此，您必须实现自己的实现，并确保商店不支持本地过滤(原因是不起作用).

You will need to overwrite the responsible provider proxy for that cause currently only property-value pairs get submitted (responsible function). The other point is that the Ext.util.Filter don't support any comparator for remotesort at all. So you have to implement your own and ensure that the store don't support local filtering (cause that won't work).

作为工作区，您可以将较小/较大的值与编码后的字符串一起提交，然后在服务器端将其减去.这只会导致本地过滤器无法获得结果.

As a workarround you can commit the smaller/bigger along with the value as encoded string and substract the it then on the serverside. This would just cause a local filter to get no results.
