I am using mod_python publisher which is set up and working fine. It allows me to run a Python file in my browser and this Python file has HTML embedded in it. I have defined a click-able image by input type = "image" onclick = "some action". When I click the image it takes me to a JavaScript function which then performs window.location = "./move" which then takes me to a Python function. The problem is that the browser window redirects to that function, i. e. localhost/scripts becomes localhost/scripts/move. Is it possible to execute the script without having the browser window change? I can post code if needs be.

Is that your own javascript function which resets window.location? What does the move function do? – sureshvv Sep 30 '15 at 07:36

yes it basically justs redirects to the python function. Move allows for a servo motor to move. So i have an arrow button that when i click it causes a servo motor to turn – Ashill Chiranjan Sep 30 '15 at 07:43

Can't you redirect back to /scripts at the end of move? – sureshvv Sep 30 '15 at 07:46

Yes i can but i have video feed that keeps refreshing when i do that. So basically the whole page refreshes again and the video feed stops and starts – Ashill Chiranjan Sep 30 '15 at 07:50

Why are you setting window.location? Can't you just call move()? – sureshvv Sep 30 '15 at 07:50

i have tried that but it does not seem to work – Ashill Chiranjan Sep 30 '15 at 08:03

You probably want to use some AJAX. – pacholik Sep 30 '15 at 08:07

"i have tried that but it does not seem to work" is not helpful. You can use the javascript debugger to see what happens. – sureshvv Sep 30 '15 at 08:20

I am sorry about that. Maybe if I post some code would that help? – Ashill Chiranjan Sep 30 '15 at 08:25

I have the same need: how to launch python code on the server from javascript without calling a script that will reload page ? (some post without any return value/feedback) – Alexandre Mazel Jan 31 '16 at 17:55

In fact, I've just found using Ajax/XmlHttpRequest is simple and work well for that, even if your server is a python SimpleServer style.
You just link this Javascript code from your button:
// send a request, but don't refresh page
xhttp = new XMLHttpRequest();
xhttp.open("GET", "?like", true);
xhttp.send();
