关于编辑文件名：
HTML5 为
a标签引入了一个新属性：download。使用它会强制支持该属性的浏览器提示文件下载，而不是导航到或尝试打开链接的文件。
此外，您分配给
download的任何值都将替换文件的实际名称。源代码和演示： http://updates.html5rocks.com /2011/08/在 HTML5-a-download 中下载资源
In regards to editing the filename:
HTML5 introduces a new attribute for
atags:download.Using it forces browsers that support the attribute to prompt for a file download, rather than navigating to or attempting to open the linked file.
Also, whatever you value you assign to
downloadwill replace the file's actual name.Source and demo: http://updates.html5rocks.com/2011/08/Downloading-resources-in-HTML5-a-download
