Is there a way to dynamically bind model values to a form in extJS 4.2?

Question

我想在模型更新后立即更新表单值，extJS（4.2）是否提供一种开箱即用的实现方式（与angular一样）

Answer 1

If possible you should use ExtJS 5 as they have now added MVVM support (read more here => http://docs.sencha.com/extjs/5.1/whats_new/5.0/whats_new.html#New_Application_Architectures___Welcome_MVVM )

So this would give you the two way data binding behaviour that AngularJS provides.

If you have to stick with using ExtJS 4 then you could listen for the store's update event and then in the listener handler call loadRecord() on your form passing in the model instance that has been updated
