问题描述

我需要浏览器来下载图像文件，就像在单击 Excel 工作表时一样.

I need the browser to download the image files just as it does while clicking on an Excel sheet.

有没有办法只使用客户端编程来做到这一点?

Is there a way to do this using client-side programming only?

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title></title>
        <script type="text/javascript" src="Scripts/jquery-1.10.2.js">
        $(document).ready(function () {
            $("*").click(function () {
                $("p").hide();
            });
        });
        </script>
    </head>

    <script type="text/javascript">
        document.onclick = function (e) {
            e = e || window.event;
            var element = e.target || e.srcElement;
            if (element.innerHTML == "Image") {
                //someFunction(element.href);
                var name = element.nameProp;
                var address = element.href;
                saveImageAs1(element.nameProp, element.href);
                return false; // Prevent default action and stop event propagation
            }
            else
                return true;
        };

        function saveImageAs1(name, adress) {
            if (confirm('you wanna save this image?')) {
                window.win = open(adress);
                //response.redirect("~/testpage.html");
                setTimeout('win.document.execCommand("SaveAs")', 100);
                setTimeout('win.close()', 500);
            }
        }
    </script>

    <body>
        <form id="form1" runat="server">
            <div>
                <p>
                    <a href="http://localhost:55298/SaveImage/demo/Sample2.xlsx" target="_blank">Excel</a><br />
                    <a href="http://localhost:55298/SaveImage/demo/abc.jpg" id="abc">Image</a>
                </p>
            </div>
        </form>
    </body>
</html>

<p><a href="http://localhost:55298/SaveImage/demo/Sample2.xlsx" target="_blank">Excel</a><br/><a href="http://localhost:55298/SaveImage/demo/abc.jpg" id="abc">图片</a></p></div></表格></身体></html>

How should it work in case of downloading an Excel sheet (what browsers do)?

在下载Excel表格的情况下应该如何工作(浏览器做什么)?
