How to best do this? 回答1: Are you using Ext.data.proxy.Ajax to load your stores? If so, you can use the reader property to evaluate and handle the server responses. Another option would be to make

问题 I have been getting UnCaught SyntaxError : Unexpected Token : . I'm really puzzled where this would come from. When i use the sample json it works http://www.sencha.com/forum/topics-browse-remote.php The issue maybe that i should use httpProxy. But i'm unsure how to incorporate this.
