Multiple AJAX calls in order

[Nutter]

I'm working on a script that needs to call a PHP script through javascript and then use the results from that script to call another. I know how to run each script independentally, but I don't know how to call the first script and wait until it completes to call the second. And the second has to wait on the first because the first returns a database id that's needed for the second.

Any tips on where to start looking?

When (request1.readyState == 4) {
make request2 ...?
}

Or, make request1 a synchronous (no 'a') request (.open("GET",url,false)) and literally wait for it to complete (freezing the client!?) before making request2 ...?

I was making that way more difficult than it needed to be. Calling another function just didn't cross my mind :)
