Menu
I have a javascript form with three sliders where a user can select three different values:
<form action="submit.php">
<div class="container">
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="red">
</div>
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="green">
</div>
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="blue">
</div>
<button type="submit" class="button">Submit</button>
</div>
</div>
</form>
I'd like to pass all three values (red, green, blue) to python so I can use them with other code, on the same computer. I tried using ajax and the example I saw here, but I think I'm submitting the form incorrectly. How can I post the data instead of calling submit.php so that I can read it with python?

Simple. Use Cherrypy
Put that in a file (say main.py):
import random
import string
import cherrypy
class StringGenerator(object):
@cherrypy.expose
def index(self):
return """<html>
<head></head>
<body>
<form name="search" action="/home" method="get">
Search: <input type="text" name="box">
<input type="submit" value="Submit">
<div class="container">
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="red">
</div>
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="green">
</div>
<div class="slidecontainer">
<input type="range" min="0" max="100" value="50" class="slider" id="blue">
</div>
<button type="submit" class="button">Submit</button>
</div>
</div>
</form>
</body>
</html>"""
@cherrypy.expose
def generate(self, length=8):
return ''.join(random.sample(string.hexdigits, int(length)))
@cherrypy.expose
def home(self, box):
print("You've entered in the form: "+ str(box))
return "THANKS"
if __name__ == '__main__':
cherrypy.quickstart(StringGenerator())
Then in a terminal:
python main.py
Then go to : http://127.0.0.1:8080 & see magic happening when you click submit (the one next to the search box I added to your code):
You've entered in the form: I entered something in the form...
I litteraly just pasted an example from the doc (& tweaked to fit your code a bit more). Other than
pip install cherrypy
you really have nothing else to do to get started. By far the easiest way to make a webserver in python imo.
Essentially, when you do
@cherrypy.expose
the name of that method becomes https://127.0.0.1:8080/my_new_endpoint
You can easily serve stuff to different endpoints & pass arguments (as shown). So you can very easily add new enpoints. See docs for details.
Have fun!
