将div内容转换为png / jpg并将其下载用户友好 [英] converting a div content to png/jpg and downloading it user friendly

问题描述

我想将div内容转换为图片并将其下载用户友好。

我使用以下代码

i want to convert a div content to image and download it user friendly.
im using following code for it

$("#btnimage").click(function () {
            html2canvas($("#print"), {
                onrendered: function (canvas) {
                    theCanvas = canvas;         
                    Canvas2Image.saveAsPNG(canvas);

                }
            });
        });

此代码有效，但用户下载时必须提供扩展。我需要弹出一个带有选定扩展名.PNG而不是.allfiles（*。*）的保存框。我找到了一个解决方案的PHP。但我在asp.net工作。这个plz帮助是否有任何解决方案

this code work but user have to give extension when downloading it. i need to popup a save box with selected extension .PNG instead of .allfiles(*.*) . I found one solution for php . but i m working in asp.net . Is there any solution for this plz help
