Now MVC uses Modelbinder, controller can now accept many complex types of parameters, but for Jquery,extjs and other JS frameworks, more of the JSON format and server-side transfer parameters more reasonable. For simple parameters, We can post directly to the server side without the JSON format. For example, the user login, we only pass the username and password into the controller: Handler:function Checklogin () {if (Form.isvalid ()) {var formvalue

is actually equivalent to assigning it an alias under the widget namespace. But alias can cover a much wider range of types than xtype. An alias can be used to declare not only the various types of namespaces as widgets, but also the types under many namespaces, such as Plugin,proxy,layout.In the Sencha Forum, a developer also explains why an additional xtype is defined when alias already exists. This is just to improve performance. In the internal i

version as a production version. This version is only used to collect performance and Neptune feedback. We estimate that some applications need to be migrated to 4.1 through some modifications in this preview version, especially those with custom la S and components. This is because we modified the underlying architecture of the layout engine, which has a certain impact on the advanced applications of the framework. We will try to solve these problems for you. We have established a special fo
