node.js意外令牌;帆布

Question

這裏是我的代碼，我無法解決爲什麼瀏覽器告訴我}};是一個意外標記在我的代碼..

script 
    var canvas = document.getElementById('canvas'); 

    canvas.width = canvas.clientWidth; 
    canvas.height = canvas.clientHeight; 

    var c = canvas.getContext('2d'); 

    var width = canvas.width; 
    var height = canvas.height; 

    var controller = new Leap.Controller(); 

    controller.on('frame' , function(frame){ 
    c.clearRect(0, 0, width, height); 
    var numberOfFingers = frame.fingers.length; 
    c.font = "200px Arial"; 
    c.textAlign = 'center'; 
    c.textBaseline = 'middle'; 
    c.fillText(numberOfFingers , width/2 , height/2); 
    }); 
    controller.connect(); 

這裏是Chrome是扔了語法錯誤，它可能很簡單，但我看不出什麼錯！

SyntaxError: /Users/plimb/Desktop/motion-therapy/views/hand.jade:33 
     31|  c.textBaseline = 'middle'; 
     32|  c.fillText(numberOfFingers , width/2 , height/2); 
    > 33|  }); 
     34|  controller.connect(); 
     35|

Answer 1

Jade試圖解釋你的嵌套，我會避免使用jade來編譯JavaScript塊。 This person had a similar problem

看看服務static content用的NodeJS

app.use(express.static(__dirname + '/js');
