extjs4

问题 With ExtJS 3.x, I was able to use the "fields" property of a Store, but it seems with ExtJS 4 I have to absolutely use a Model. It's fine, but in my case, it's not a static Model, and I need to define the fields on the fly and sometimes to change them.

A good ergonomic choice would to create search fields in the column headers, like @Ctacus shows in his question. How can this be achieved ? 回答1: After quite much research through the sparse documentation,

问题 I am working with Extjs4. I am trying to send accented characters to server. I was trying to send ó. And what I was receiving at the server side was ó. I am sending it using Store proxy. In store proxy, I have added headers: { 'Content-Type': 'charset=utf-8' } Still it did not send the accented characters properly. How should I send accented characters to the server? Thanks in advance! 回答1: user2316489, IMHO this is a problem with your server configuration, rather than a front-end
