Javascript 如何使用ajax对正在显示和筛选的记录进行分页
我有一个页面，列出了页面上的所有属性。此记录根据单击的复选框进行筛选。如何进行分页。如果未应用任何筛选器，我希望对记录进行分页。同时应用筛选时，我希望对显示的记录也应用分页。我该怎么做？下面是一个例子 执行过滤的示例代码。多谢各位 这是我到目前为止的分页代码。但如何将其应用于过滤记录Javascript 如何使用ajax对正在显示和筛选的记录进行分页,javascript,php,ajax,mysqli,Javascript,Php,Ajax,Mysqli,我有一个页面，列出了页面上的所有属性。此记录根据单击的复选框进行筛选。如何进行分页。如果未应用任何筛选器，我希望对记录进行分页。同时应用筛选时，我希望对显示的记录也应用分页。我该怎么做？下面是一个例子 执行过滤的示例代码。多谢各位 这是我到目前为止的分页代码。但如何将其应用于过滤记录 $totalProperty = "SELECT * FROM property_listing WHERE property_status = 'approved' "; $allProperty = mys

要生成分页，请使用包含两个参数的LIMIT
子句。第一个参数为OFFSET
，第二个参数为应该从数据库返回多少条记录
这是参考资料：小心！您的代码易受SQL注入攻击。有关更多信息，请查看并感谢@Rahul。不过我是个新手，会努力的。谢谢@Rahul。但是如何应用数据库中的过滤结果呢？这可以通过Jquery、AJAX将值发送到PHP中。如果你需要，我将与你分享参考。请分享参考参考参考：谢谢@Rahul。我的代码就是这样做的。我现在只需要为你发送的参考资料分页。我已经尽力了。非常感谢。
