Nowadays, Ajax is widely used, but it does not apply to every place. For example, for a secondary drop-down menu of a province, city, or county, the data is relatively fixed, you can directly create a JS file, so there is no need to extract the database from the database every time. In addition, when reading data, you must properly remind users that they are reading and downloading data. Otherwise, when users who are used to page Jump find that there is no dynamic activity for half a day, they think that IE is faulty again.
