The simple answer is: you can't.

The complex answer is: call-server-1; wait for reply; handle reply; call-server-2; ..... This should all be coded inside your formapi, while taking care of unexpected situations like 404-erros, 500-errors, invalid js, etc.

To expand a bit on the above - callServer processes are asynchronous and cannot be run concurrently - to do so requires that the script itself reference a callback function within the FormAPI layer that can then take care of launching the next instance of the script (assuming the first was successful).

E.g.:

The names "foo.ipl", "all_ok" and "not_ok" are arbitrary on my part - they can be named whatever you want them to be.The other alternative is to write your own code using "raw" javascript or jquery code to perform synchronous calls to a server-side script - again it's serial not concurrent, but you would control the sequencing entirely from the FormAPI layer rather than requiring callback functions (though they're still a good idea)

How to call the callserver in javascript multiple times?

As noted, you can execute callServer only sequentially, synchronization is your own problem.

Few years ago Jeff Bonifaci and Jonathan Gulbrandsen published JS library that allows the user to
create sort of FIFO callServer queue. It will take care of calls synchronization, etc. Take a look, perhaps
a layer like that is all you need.
