More efficient, would be coding directly in HTML. So Yusef solution, with a "Button Look Alike" Style (see How do I make an html link look like a button?for example), would simply be coded like this:
更高效,将直接在 HTML 中编码。因此,具有“按钮外观相似”样式的 Yusef 解决方案(请参阅如何使 html 链接看起来像按钮?例如),将简单地编码为:
<a id='download-btn' href='/sites/default/files/toy/jpeg/image-1419683919_4851.jpeg'
download='MyToy.jpeg' class="button">Save as MyToy.jpeg</a>
