In this article, we’ll take a quick look at what these new attributes are, and how they can be used once browser support improves. The download Attribute. The download attribute is new in HTML5. It supplements the existing href attribute by telling the browser that the resource the href points to should be downloaded directly, instead of visited (which could happen with a file that the browser can open, like a PDF). The value of the download attribute is used for the name of the file that is downloaded. The download attribute can be the same as the file referenced in the href attribute, but it doesn’t have to be. Being able to have different values for href and download can come in handy. For example, you might need to generate unique files dynamically on the server for monthly or yearly reports on a per user basis, but still present the user with a meaningful filename for when they download a file. Because the download attribute can be different to the href, this is pretty easy to do: < a href=. In practice this isn’t quite true, as you’ll need to bear in mind the restrictions operating systems impose on which characters can’t be used in filenames — such as the backslash . It’s also worth noting that the download attribute’s value can be overridden by the Content- Disposition HTTP header’s filename parameter. The download attribute can be used with blob and data URI’s, which makes it useful where users need to be able to save dynamic content they’ve created through your web application (e.

If you’ve worked with CSS, then you’ve come across the media attribute before, and you’ve probably used it on the link tag. In HTML5 the media attribute can now also be applied to a hyperlink. It works in the same way, and its value can be any valid media query. When applied to the < a> tag, the media attribute is used in a purely advisory capacity. It could be useful, for example, in situations where you provide device- specific downloads, such as for desktop and mobile wallpapers: < ul>. It’s listed as an HTML5 attribute on MDN’s HTML reference but it’s not listed as a valid attribute on the WHATWG spec or on W3. C. The ping Attribute. Finally, let’s look at the new ping attribute. This attribute takes a space- separated list of URL’s that are to be pinged should the user successfully navigate to the href of the hyperlink. Or, to put it another way, it provides native support for click and link tracking: < ul>. Well, the idea is that it gives users greater transparency in seeing what other requests may be made as a result of them clicking on a certain link. It’s this greater transparency that is why authors are being encouraged to use this attribute. It’s been suggested that browsers should allow users to configure how ping notifications are handled e. Browsers could also display the ping URL alongside the link location in the browser’s status bar. Browser Support for the ping Attribute. Current browser support for ping is mixed. Safari and Chrome do support it, Firefox has support for it but by default it is disabled, and IE and Opera do not support it. It’s also worth noting that the ping attribute is not in the current W3. C HTML5 draft spec, but it is in the WHATWG HTML5 spec. Summary. So that’s 3 new attributes that were added to the < a> element in HTML5 — download, media, and ping. As you can see, when these gain better browser support, they will be quite useful and have lots of potential use cases.
