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– sureshvv09/30/2015 07:36:55Commented Sep 30, 2015 at 7:36

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 turnAshill Chiranjan– Ashill Chiranjan09/30/2015 07:43:17Commented Sep 30, 2015 at 7:43

Why are you setting window.location? Can't you just call move()?sureshvv– sureshvv09/30/2015 07:50:46Commented Sep 30, 2015 at 7:50

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();
