JavaScript, frameworks and paradigms?

Question

JavaScript

Recommend Javascript framework for developing administration interface with complex forms. I made a working prototype using jQuery and dozens of plugins (tabs, drag&drop, ajax file upload, data link, mousewheel, hotkeys...). But now it is necessary to supplement the interface with all the necessary fields, and I understand that I have to copy a lot of code, and field identifiers are scattered throughout the script. You need the right programming paradigm. I think some lightweight framework can give it.
Watched DoJo. There, of course, there is everything you need. But now I don't have a month to study this system. In addition, our administration system is designed in such a way that it will not be possible to use the ready-made visual components that DoJo provides. So the whole meaning is lost. Roughly the same story with YUI.
You need a tool that will manage the interaction of ready-made visual elements (which are written using a lot of jQuery and plugins).
From the server, I receive a large json, which contains all the necessary data of the edited object. There are also a few additional json objects with values ​​for all sorts of drop-down lists and forms with auto-substitution. You need to return json with the same structure. Drag&drop is actively used inside forms. There are no page reloads.
Links to examples of good interfaces would also be helpful. Thank you.
