simple ajax question

I have to send mail before submitting my php page, I am submitting the page using javascript. my mail script is in sendmails.php file. so can I send an ajax request to send mail before submitting the page using java script ? like follows 

function submit_page()
{
//trying to run send_mail.php
..............................//ajax codes
............................
xmlhttp.open("GET","send_mail.php",true);
xmlhttp.send();
.................................

if(a)
form.action = 'one.php'
else
form.action = 'two.php'
form.submit()//form submitting using javascript
}

Will it run the send_mail.php file in the server ?

Thank you

I doubt it - ajax requests take a certain amount of time to complete, and you're navigating away from the page immediately, which will interfere with the request.

Suggestion - do the ajax request in synchronous mode. That way you're guaranteed it will finish before the form submits.

Yes but don't rely on the fact that this happens before send() returns. send() just starts a background thread which will eventually open the connection to send_mail.php and post the form. So it can happen that the form is submitted before the mail is sent.
