![]() These attributes are supported by all HTML5 tags, with very few exceptions. The tag supports the full range of standard attributes in HTML5. You can use any HTML elements that are supported within the tag, such as italics, bold, links, objects such as Flash, etc. You will likely want to include some text inside the tag so that users whose browsers do not support the tag will have a clue as to what is going on (and why they aren’t seeing the audio control on the page). You can also include the source file’s location in the beginning tag, rather than between the two, like this: Īlso note that you can point the srcto a file located on the server with your web page (a relative URL, like /audio/music.ogg), or a file located elsewhere on the web (an absolute URL, such as ). You use the tag just like you use any other element: Your browser does not support the audio element. ![]() Here is the audio tag in use (obviously you will only see it if your browser supports it): When Safari, for instance, comes across the tag, it will ignore the. ogg (one audio conversion tool, media.io, can be used online) or just supply two versions of your audio file, one in each format. The good news is that you can either convert your files from. Others, such as Firefox, only support the. Currently any recent browser that is based on Webkit, such as Chrome and Safari, supports the use of regular. That said, it does have limitations on the types of files that can be used. The tag is new to HTML, like the tag, and allows developers to embed music on their websites (and unlike earlier attempts to add audio to a website, it isn’t limited to old-fashioned midi music). This week we’re going to expand upon our discussion on multimediaand delve further into HTML5’s tag. PlayButton.In our series on HTML5, we’ve discussed geolocation, link relations, form and keyboard events, media events, mouse events, global attributes and multimedia. Change the toggle button’s value to show that the next time the user clicks, it will toggle from pause to play or play to pause.If the video has previously finished, and our playhead is right at the end of the video, then we also need to reset the current time to 0, that is, move the playhead back to the start of the video, before we start playing it. If the user clicks on the toggle and the video is currently paused, the video should start playing. ![]() In the play/pause toggle, we have a number of things to do: Our hand-rolled basic video player controls will have a play/pause toggle button and allow the user to scrub along the timeline of the video to skip to a specific section, as shown in Figure 4.3.įigure 4.4 Using XML entities to represent play and pause buttons.įor simplicity, I’ve included the button element as markup, but as we’re progressively enhancing our video controls, all of these additional elements (for play, pause, scrubbing, and so on) should be generated by the JavaScript. So if you want to style it your own way, it’s easy with just a bit of web standards knowledge-no need to edit an external Flash Player or similar. The best bit is that the UI will be all CSS and HTML. Our example won’t blow your mind-it isn’t nearly as sexy as the element itself (and is a little contrived!)-but you’ll get a good idea of what’s possible through scripting. In our example, we walk you through some of the ways to control the video element and create a simple set of controls. Using JavaScript and the new media API, you have complete control over your multimedia-at its simplest, this means that you can easily create and manage your own video player controls. Table 4.3 Media Attributes, Methods, and Events Table 4.3 provides a reference list of media attributes, methods, and events. Everything else is events and attributes. In fact, that’s all the methods on the media element. With that in mind, we’ll stick with the sexier media element: the element for our JavaScript discussion.Īs you saw at the start of this chapter, Anne van Kesteren has spoken about the new API and about the new simple methods such as play(), pause() (there’s no stop method: simply pause and move to the start), load(), and canPlayType(). The API’s events and methods are the same for both and. One truly spiffing aspect of the and media elements is that they come with a super easy JavaScript API.
