Question

I Have ExtJS client-side programm that communicates with server using synchronous AJAX. Over 95% responses incoming at less of 1 second but there a few cases when server can execute commands during 10 seconds or more. That’s why I need some mechanism that can tell to user that this is not a bug (“pls wait” form)

So. I need something like

1. send request;
2. setTimeOut(‘show loading form’, 2 sec);
3. wait for response
4. close loading form
5. process response.

Is there some way to execute some function while waiting synchronous AJAX response?

P. S. I use synchronous because of legacy, there is no way to correct it (best way – over 6 month of work).

Answer 1

There is no such methods, but it can be implement by hooking all events while async request is going…
