All input variables are in the ultra-Global Array. Please describe your requirements

I want to use the received AJAX value in other functions. I want to set the POST value to a global variable and call it directly.

When ajax is used by default, the async option is true, that is, an asynchronous request. in this case, the asynchronous request cannot pass the return value to the global variable and set async to a synchronous request, that is, async = false;

The POST value is originally global and can be used directly in functions.
