In many cases, we need to display tens of thousands of data records in the grid instead of just a few or dozens. If a large amount of data is displayed on a single page, you can imagine the user experience. Therefore, almost all grid controls now support the paging function. Extjs is no exception. It also provides powerful and convenient support for paging, so that we can easily handle paging. In extjs, the

Therefore, almost all grid controls now support the paging function. Extjs is no exception. It also provides powerful and convenient support for paging, so that we can easily handle paging.In extjs, the Ext. PagingToolbar class encapsulates paging operations, which are inherited from the Toolbar. From the name alone, we can also guess that this is a Toolbar that can process paging.

for extjs development. In the body section, there is a piece of JS Code, and the specific significance of this Code is not too much attention now, which will be described in more detail in later sections. Save this code as an extjs-helloworld.html file. to properly introduce necessary resources, we need to pay special attention to the path to store this file. It should be placed at the same level of

prefix is not a Null String, check whether the prefix is of the same type. If the prefix is the same, retrieve the path from the paths object and return it directly. Otherwise, the prefix path is taken out and the prefix of the class name is removed.Then, determine whether the path exists. If it does not exist, add a slash (/) to the path.Finally, convert the class name to the file name with ". js" and add the path to return. Note that if the class name contains ".", it will convert "." to "/",

information that is valid for the user's current logon. Otherwise, an error is returned. The client parses the login information. If the token is invalid, for example, if the user is locked or deleted by the Administrator, the system reports that the logon fails and redirects to the logon interface. Otherwise, do nothing. In this way, we can achieve: Any changes to user information will be reflected in a timely manner. For example, if the user receives a new system short mes
