Cannot get HTML file to call JavaScript function hello() on Ubuntu Apache 2. I have seen similar problems where the solution was to uncomment the #JSDIR line on the httpd.conf file but there is now only apache.conf and no similar line. I want to call the python script accesstest.py to write the current date and time to a text file from the main.js function after clicking the button on the HTML file. All of the files work correctly when run separately. How do I fix this?

index.html HTML code: 

<!DOCTYPE html>
<html lang="en">
<head>
    <title><demo</title>
</head>
<body>
    <h1></h1>
    <script src="main.js"></script>
    <button onclick="hello();">js function</button>
</body>
</html>

main.js JavaScript code:

let myHeading = document.querySelector('h1');
myHeading.textContent = 'Hello world!';

function hello(){
    var spawn = require("child_process").spawn;
    var process = spawn('python,["accesstest.py"]);
    alert('hello');
}

accesstest.py Python code:

import datetime
def execute():
    file = open('/path/to/file/pytest.txt', 'a+')
    file.write('test time: %s \n' % (datetime.datetime.now()))
    file.close()
execute()

Here is the display:

page displays "Hello World!" with "js function button" that does nothing

Here are a couple solutions I found that didn't work for me:

Unable to call JavaScript function in html on button click

How to link external javascript file onclick of button

Thanks.

  • I think you're confusing the JS you write for the browser, and the JS you write for the CLI. – Joseph Sep 30 '19 at 19:39
  • You cant execute Python in the browser like this. `spawn` might work within nodejs, but not embedded in HTML+Javascript – Maurice Meyer Sep 30 '19 at 19:51
