I currently have a div tag that contains a bunch of other within it, and together they represent a line-graph. What I want to do is export this line-graph to an image(.png, .jpeg, etc) so that the user can download it. How can I do this?

It's a JSP web page, using JavaScript, jQuery and the back-end is handled by Java.

从这个答案：使用 html2canvas 将 div 捕获到图像中

您也许可以使用 html2canvas 来完成这项工作。我从来没有使用过它，所以我不能肯定地告诉你。

我不认为这可以用div. 但是如果你使用了这个canvas元素，这是可能的：
