Html converts to img (將html 輸出成img格式)

gistfile1.html

<!--baseURL 就是 輸出的img src 連結-->
<!--該Html 引用<script type="text/javascript" src="http://html2canvas.hertzen.com/build/html2canvas.js"></script>--> 
<!--Ext.getCmp('wincv-1110').el.dom ,即是該html的DOM-->
<!--參考 html2canvas : http://html2canvas.hertzen.com/-->
 <script type="text/javascript" src="http://html2canvas.hertzen.com/build/html2canvas.js"></script>
 <script>
 html2canvas(Ext.getCmp('wincv-1110').el.dom,{onrendered:function(canvas){
      var baseURL = canvas.toDataURL("img/png");
     console.log(baseURL);
 }});  
 </script>
