How to run python function from javascript?

Question

I have a problem in calling my python function from my javascript file.

I'm using a simple server with python3 -m http.server , so no actual backend..my javascripts are in the front end.

I have a python file called write.py it has a function that I want to execute from my javascript file

write.py file:

def save_vit(text,name):
    f = open(name + ".xml", "w+")
    f.write(text)
    f.close()

the javascript part that i have tried:(but didn't work)

$.ajax({
        type: "POST",
        url: "write.py",
        data: { text: xmlDoc,name: name}});

xmlDoc is a string that has an xml document.

name is a variable that has the name of the file for the python function.

So my question is, what am I missing to call write.py from my js file or how to call it if this approach is wrong?

Answer 1

You are using http.server to serve the content of a folder, as files, not to execute them, so in the best case scenario, http.server will respond with the content of the write.py file instead of executing it.

You need to create a webserver that has a endpoint where the code of write.py is integrated.

Answer 2

You can't send a POST http request to run a python script.

You need to have the python script running on a server, that is able to take restful API calls, to run the script and return a value.

For example, you can run a small flask app that takes in your POST route, which runs a script and returns the value of the script back to the client that accessed the POST route.

Answer 3

Python is running on the server side ... JavaScript is running on the client side.

So, the only way for JavaScript to ask for a Python routine to be run is through an asynchronous AJAX request which you will have to build.
