问题 I want to override some config options of Ext.form.NumberField, but I don't find something like a "thousands separator". Is there a way to define this for NumberFields in Ext? Or have I had to write my own function to provide this functionality? 回答1: On closer inspection according to the forums/devs, NumberField doesn't support formatting. Numbercolumn on a grid does.

问题 I'm using ExtJs for UI and am doubtful of using CSRFGuard in AjaxRequest of extjs. I'm currently appending the CSRFName and value to the URL of ajax and it is working perfectly fine.
