how read data in python script called from javascript post

Question

I would like to pass data from a javascript to a python script called test.py, when the button is clicked.

The web page contains the following script:

<script>
$(document).ready(function(){
  $("button").click(function(){
    $.post("/cgi-bin/test.py",
   { name: "Zara" };
    });
  });
});
</script>

<button type="submit">Run</button>

Here is the test.py that runs in the same server of the web page:

#!/usr/python
print('Content-Type: text/html; charset=utf-8\n')
import sys
file = open('/var/www/cgi-bin/temp.txt','w')
file.write(sys.argv[1])
file.close()

I expected that the temp.txt contains the name Zara. But temp.txt is empty.

So my question is:

How the python script gets the argument name from javascript? Can I use sys.argv or i need another python library?

try running the python executable 'c:\python27\python.exe' on windows, with /cgi-bin/test.py as the first argument and the arguments you need to send to the python script as the next arguments. then you should be able to use sys.argv in your py script — Ionut Hulub

Thanks, but reading the question again, I think this was not so clear. test.py is a python script that runs in the same server of the web page. I will add test.py in the question. — danielmsd

JavaScript sends a regular HTTP Post request and the python script can parse it as a regular CGI script:

#!/usr/python
import cgi
print('Content-Type: text/html; charset=utf-8\n')
form = cgi.FieldStorage()

if 'name' in form:
    with open('/var/www/cgi-bin/temp.txt','w') as file:
        file.write(form['name'])

Thanks, but i think instead of sys.argv[1], the command would be form.getvalue('name'), right?
