How to configure ExtJS 4 Store (proxy and reader) to read metadata

Question

My question is how to get metadata besides totalRecords, in my case it is version, code, searchquery (please look at json).

{
\"result\": {
    \"version\":\"1\         


        

Answer 1

Take a look at Ext.data.Proxy class and more specifically processResponse() method. If you need to extract any additional data - you will have to extend standard class and change that method.
