It can be seen from the dynamic picture that when you click the like button, the number of likes next to it increases without refreshing. You can also see that the number of likes has been updated when you open the database.

First of all, the front-end page is a button and the number of likes.

Database name, test, table name zan, field zan

ajaxindex.php

       
  赞      ajaxindex.js $(document).ready(function(){ $("#btn").on("click",function(){ $.get("sever.php",{name:$("#btn").val()},function(data){ $("#result").text(data); }); }); });

sever.php

General idea:

Click the button through ajaxindex.php, js will react, ajax will be submitted asynchronously to sever.php and then returned to the page through js, so there is no need to refresh.
