?>Question 1: The callback function console.log(data) can be printed, but $('p.show').html(data) this step runs successfully The probability is very low, and every time it happens, it's like having a convulsion.
Question 2: In the console network (Google), the requested ser.php is not always available. Trouble...

I tested it with the code you wrote. There is no problem and there is no problem at all. That's strange!

The code looks fine and actually runs fine.
It is recommended to check the browser’s proxy, plug-ins, etc. and the current network environment
If it is a development environment, you can try to change the development environment for testing. In the production environment, please check whether there are any problems with the system configuration, firewall, etc.

Console network (Google), the requested ser.php is not always available.
Get request, if the address requested each time is the same, the browser will cache it. So in order to make the request possible every time, the usual approach is to add a random number to the request parameter, such as url:xxx.com?a=1&r=Math.radom()
