How to pass variable from python to javascript

Question

I have a server in python to process an id (the id of youtube video), this is the code:

class MessageHandler(tornado.web.RequestHandler): 
  def get(self, action         


        

Answer 1

It looks like you're using Tornado. You can write raw Python in a Tornado template. Your player.js file is a Tornado template in this case. You would want to update it like this:

var PushPlayer = (function () {

var player = null;

function new_player() {
    player = new YT.Player('yt-player', {
        videoId: {{ action_id }},
        }
    });
}

Anthing inside the double curly braces will be evaluated as Python by Tornado.
