Hello friends -

I have a rails app that uses JSON to send requests to another server.  
That  
server processes the request and sends a JSON response back to the rails  
app.

At first I was sending the requests using AJAX but the requests may take  
up  
to 30 seconds, and users double-submitted, reloaded, etc. So, I was  
thinking  
that upon submitting a request, I could then have rails forward to a  
“Please  
wait while we are processing your request” page. From there, rails will  
send  
the request and wait for a response. When the response is received (or a  
timeout of 45 seconds is reached), I can redirect appropriately to the  
result page.

My question is, I am not sure how to achieve this effect of having a  
“Please  
wait” page while asynchronously checking another server for a result.  
Does  
anyone have any tutorials/advice/links on how to achieve this?

Alternatively, I have seen (using prototype or jquery) sites where when  
you  
press the submit button, the screen greys out and a window is tiled on  
top  
informing the user that the request is being processed. Is it possible  
to  
utilize this method using ajax?

Thanks,  
Jin

You can just use a loading panel (that is also modal) to keep the user  
from double submiting →
