Setting pageSize in jquery datagrid does not work

Recently, a problem was found: jquery datagrid setting pageSize does not work. After research, the solution is as follows: $ ("# dataGrid "). datagrid ({pageList: [4, 8, 16], // you can set the list of records per page. pageSize: 8 // The number of records per page )} it must be configured during initialization, if it is in $ ('# dataGrid '). datagrid ('getpager '). pagination ({....}) in the configuration, due to the loading order, pageSize values are not assigned during page loading, which may be not perfect in jquery. As for some people, it is incorrect to write in pagination in getPager in the demo ..
