Small comparison of extjs, jquery, and dojo

These are all famous gangs in the JS library. I used dojo before. Now I have not used extjs or jquery. I just read the documents on the official website.

Extjs: the first is that the API docoment has done a very good job, and the components that have been implemented are almost all-encompassing. After changing the example to a few days, you can come up with a decent interface. Extjs's programming philosophy is a bit similar to swing or something similar, that is, to discard the layout of HTML itself (through renderto and other usage, you can also specify the DIV component of the HTML file, but there is no chance of encountering the hierarchical relationship between divs). use JavaScript to build a full set of pages from scratch. The disadvantage of this approach is that it is not intuitive. In addition, extjs does not abstract the concepts of action and effect as jquery does. In a panel, even the attributes such as animate are used to fade in and out the panel. This is a bad way to bind behavior and object together. Jquery: The syntax is concise, and the concepts such as actions and special effects are abstracted. In this way, the components themselves are separated from those that support such operations and special effects. Dojo: it used to be famous for its comprehensive components, not only the UI components, but also other non-UI components (such as map), and even some 3D components, in the past, when HTML did not support canvas, Dojo had such a component. Dojo. Require is very creative in managing dependencies. Its disadvantage is that it is difficult to write. To:Http://linmingren2003.blog.163.com/blog/static/567510032010424114059334/
