About ext, ajax should not be just ext. At this time, I may be more inclined to jquery, but jquery's plug-in

About ext, ajax should not be just ext. After reading the five-page discussion, I feel that most people do not support ext. Although ext may be the most popular ajax framework, but she does have a lot of problems.
1. For example, the hot issue of license recently discussed is naturally very serious,
2. ext has 400 Kb, which is indeed a little large for the client.
3. Check whether the speed of ext is a problem. I have not tested it. However, it seems that there is a problem with the speed as discussed in the Forum.
4. Extension and modification of ext. Sometimes, when ext cannot meet the requirements, you can modify the content of ext by yourself. css is very difficult to modify.
5. It seems that jquery is more popular, small in size, and easy to modify. However, the demo interface is generally not as nice as ext.
6. Tree, table, and form are widely used, and these jquey also provide plug-ins. However, it is said that the official website has not officially announced the use of these plug-ins.
To add this question, we are still looking for jquery plug-ins today. They are not very nice, such as calendar and grid. In particular, there are very few grid styles, none of them look good. It's really no match with ext,

The following is a forum discussion. If you are interested, go in and have a look.

I strongly agree with the title of the landlord. I also think ext is too dead. Although it is gorgeous, when you see more, you will review the beauty fatigue. Oh, it's ext again. I prefer to build my own wheels. I like to build wheels on jquery. I think jquery's ui should also be aware of the css problem that cannot be easily changed by ext. jquery's ui has a topic package. I think this is a good direction. Looking forward to jquery

Some Internet projects I am working on now only use extjs in the background, and the foreground uses basic libraries such as jquery. After all, the number of backend users is relatively small and the development speed is relatively high. If extjs is used at the front end, It is very worried about compatibility and speed.
