推荐答案

html2canvas2 JavaScript实用程序适用于截取以下内容的屏幕截图一个网页.您必须使用三个JavaScript库:

The html2canvas2 JavaScript utility is suitable to take a screenshot of a webpage. You have to use three JavaScript libraries:

 1.jquery-1.10.2.min.js
 2.html2canvas.js
 3.jquery.plugin.html2canvas.js

然后调用函数capture()，它将在新窗口中为您提供基于HTML5画布的屏幕截图.它还生成image的base64data值.它仅在支持HTML5 canvas的浏览器中起作用.

Then call the function capture(), which will give you an HTML5 canvas-based screenshot in new window. It also generates a base64data value of image. It only works in browsers that support HTML5 canvas.

    <script type="text/javascript">
    function capture() {
            html2canvas($('body'),{
                onrendered: function (canvas) {                     
                            var imgString = canvas.toDataURL("image/png");
                            window.open(imgString);                  
            }
        });
   </script>
