The processor total is divided into two categories:
One is a return to the page, the processor returns all pages, will refresh the page, the corresponding request should be synchronized request.
One is to return a result, all results returned processor, the requester must need the result value, then you need a way to request a callback function, which is an asynchronous request ajax.
So, in the future development, as long as the return to a page you think of sync, as long as a return value to consider asynchronous.
It returns a value in two ways:
method one
- Front-end interface
- Background code
But the value returned by the above method if the Chinese will be garbled
Then it sets through produces.
Second way
- Front page
- Background code
