Recently, I used jquery to develop my website. It is the best Ajax framework I have used. It is lightweight and easy to use. prototype is getting bigger and bigger, and extjs is available, it is also hard to say that if the network is poor and it needs to be applied to the application, but it is really good for interface development. If it is used with the Enterprise Intranet management system, I think the results are very good. DWR is also a very convenient Ajax framework, and you don't need much JavascriptCodeYou can access remote Java objects on the server, and it can also be integrated with many frameworks, such as struts, hibernate, spring, and JSF, in short, you can find your favorite Ajax framework in development and adapt it to the development environment of your enterprise, because you cannot change the Ajax framework used by the enterprise development team based on your personal preferences.
