如何从蟒蛇到JavaScript的变量传递 [英] How to pass variable from python to javascript

问题描述

我在蟒蛇处理一个ID（YouTube视频的ID）的服务器，这是code：

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_id): 
    print "Message = " + action_id 

    if action_id == "id":
        for ws in opened_ws: 
            ws.write_message("ID: " + action_id)
            return render_template('js/player.js', action_id=json.dumps(action_id))
(...)

我使用返回render_template传的action_id来player.js，这是处理使用从YouTube API膜的功能，code是：

I use the return render_template to pass "action_id" to player.js, which is a function to process films using the API from Youtube, the code is :

var PushPlayer = (function () {

    var player = null;

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

(...)

使用的action_id ，我可以有YouTube的视频的一切ID ..但我不知道是谁传的action_id 从Python来javascript..any想法？

With action_id, i can have everything id of youtube's video.. but i don't know who pass the action_id from python to javascript..any idea?

谢谢！

推荐答案

它看起来像你使用旋风。您可以在龙卷风模板写入原始的Pyt​​hon。您的player.js文件是在这种情况下，一个旋风模板。你想这样来更新它：

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 }},
        }
    });
}

双花括号内Anthing会像Python由龙卷风进行评估。

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