Basically the idea goes like this:
- you send and XHR call to server and execute script
- script checks if there is already a background process
- if there is one, return the status code
- if on background script running: script forks itself , returns an "OK" response and start to do the work
- with a different XHR call you repeatedly check if script has finished
- when the server-side script has finished running, you gather the results and diplay in the page
To simplify the interaction with server, you might want to use some of the XHR libraries. I would avoid suggest to avoid slapping on jquery unless you are actually already using it for something else.
As for "how to know when background script has finished" : i think the best way would be for that script to create a file, which contains
- when running: -1
- when finished: 0
- when error: positive number

Jquery + AJAX could make your job easier. Read this tutorial on how to achieve the result:
