The thinkPHP framework can add a complete sample code of the paging class for js events

This article mainly introduces the thinkPHP framework The paging class customPage.class.php that can add js events, and the paging class customPage.class is given in the form of a complete example. PHP implementation code and analysis of ajax dynamic loading of data, setting of paging links and other functions, friends in need can refer to the following
