以上是包含基本64位编码的csv数据导出的数据URI。在我的应用报告页面上，我将导出嵌入到每个页面视图中，以便导出不需要再次访问数据库。
在Firefox 3中，单击此链接将打开另存为“下载”对话框。在Chrome 9中单击它不会做任何事情。我可以在Chrome中右键单击保存，它会将解码后的csv写入文件。在Safari中单击它会在浏览器窗口中打开解码的CSV数据，然后我可以手动保存。
在IE中......谁在乎，我是对的吗？
您可以通过将<a>标记全部复制到名为test.html的空白文件中并在每个浏览器中打开它来重现此测试。它的行为与我的应用程序环境中的行为完全相同。
问题：当用户点击数据URI链接时，有没有办法强制弹出“另存为”对话框，就像在Firefox中一样？或者其他一些方法来解决这种不一致问题？
理论上，Firefox，Chrome和Safari都支持数据URI。在实践中.......
答案 0 :(得分：2)
不幸的是，在Safari（至少Safari 6）中，application / octet-stream不能很好地工作。它只是将文件保存为“未知”而没有“保存”对话框。据我所知，除了从服务器上反弹内容之外，没有跨浏览器的方式去做你想要做的事情。
