Question

我刚开始使用python和flask（对于raspberry pi）。我想要一个显示来自mysql的数据的Web应用程序而没有刷新页面我试过这个

    app = Flask(__name__)
    app.config['MYSQL_HOST'] = 'localhost'
    app.config['MYSQL_USER'] = 'root'
    app.config['MYSQL_PASSWORD'] = 'raspberry'
    app.config['MYSQL_DB'] = 'tesdb'
    mysql = MySQL(app)


    @app.route('/')
    def interactive():
        return render_template('interactive.html')
    @app.route('/ambildata')
    def ambildata():
    cur = mysql.connection.cursor()
    cur.execute('''SELECT*FROM contoh WHERE id = 1''')
    result = cur.fetchall()
    return jsonify(result = result)

interactive.html

<html>
<head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type=text/javascript>
        $(document).ready(function(){
            setInterval(function (data) {
              $("#result").text(data.result);
          }, 3000);
        });
    </script>
</head>

<body>
    <div class='container'>


    <p id=result></p>
    </div>
</body>

但我无法看到网页上的数据

无需刷新页面即可获取mysql
