The html2canvas2JavaScript utility is suitable to take a screenshot of a webpage. You have to use three JavaScript libraries:
该html2canvas2的JavaScript工具是适合于拍摄网页的屏幕截图。您必须使用三个 JavaScript 库：
1.jquery-1.10.2.min.js
2.html2canvas.js
3.jquery.plugin.html2canvas.js
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.
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。它还生成图像的 base64data 值。它仅适用于支持 HTML5 画布的浏览器。
<script type="text/javascript">
function capture() {
html2canvas($('body'),{
onrendered: function (canvas) {
var imgString = canvas.toDataURL("image/png");
window.open(imgString);
}
});
</script>
