我想访问DOM并通过id获取一个元素:我想从我的html文件中获取image.src,如下所示:

<!DOCTYPE html> 
<html> 
  <head> 
    <meta charset="UTF-8"> 
    <title>Diagram</title> 

    <script type="text/javascript" src="lib/jquery-1.8.1.js"></script> 
//    <!-- I use many resources -->
    <script></script> 

    <script> 

      function generatePNG (oViewer) { 
        var oImageOptions = { 
          includeDecoratorLayers: false, 
          replaceImageURL: true 
        }; 

        var sResultd = new Date(); 
        var h = d.getHours(); 
        var m = d.getMinutes(); 
        var s = d.getSeconds(); 

        var sFileName = "diagram" + h.toString() + m.toString() + s.toString() + ".png"; 

        var sResultBlob = oViewer.generateImageBlob(function(sBlob) { 
          b = 64; 
          var reader = new window.FileReader(); 
          reader.readAsDataURL(sBlob); 
          reader.onloadend = function() { 
            base64data = reader.result; 
            var image = document.createElement('img'); 
            image.setAttribute("id", "GraphImage"); 
            image.src = base64data; 
            document.body.appendChild(image);
          }  
        }, "image/png", oImageOptions); 
        return sResult; 
      } 
    </script> 
  </head> 
  <body > 
    <div id="diagramContainer"></div> 
  </body> 
</html>

除了nodejs,phantomjs,我可以使用什么其他javascript-server从html文件中通过id获取元素?
