    HTML 5.0 new Supporting Features

    Hey Folks,

    There is lot of hype/expectations around HTML 5.0. So I was looking for more details about new features in HTML5.0 & also how these features will be working in various browsers.
    I think Geo location is/will be the one of the hottest topic/feature, I found one good article about HTML5 and its features…. Surprisingly this link is coming from Samsung’s developer forum aka Samsung Mobile Innovator..(I didn’t know that Samsung is also supporting/influencing HTML5.0 features so that their mobile browsers can support rich web experience… Samsung that’s the way to go….. )



    Some of the details:

    Article Tag
    The Article element represents an independent section of a document, page or site. For Ex: Articles are suitable for contents like news, blogs, forum posts or individual comments.

    File Browsing
    Input type File attribute is used for browsing the files present on the phone or pc. This is not supported on Mobiles. For Ex: The below given image shows the clear description how it works.

    Geo-location using HTML5
    This feature supported on web. This feature is not supported on wave device.

    function showMap(position)
    {
    alert(position.coords.latitude, position.coords.longitude);
    document.getElementById('latitude').innerHTML = position.coords.latitude;
    document.getElementById('longitude').innerHTML = position.coords.longitude;
    }

    Offline Web Application
    In order to enable users to continue interacting with web applications and documents even when their network connection is unavailable Ex: when user is travelling outside of the ISP’s coverage area – authors can provide a manifest which lists the files that are needed for the web application to work offline and which causes the users browser to keep a copy of the files for use offline.

    You can find full code and details from the above link. Know the new features in easy way.

    Please do feel free to share other good links on HTML 5.0 ….

    Re: HTML 5.0 new Supporting Features

    Today we will look at 5 of these exciting HTML 5 features and its implementation.

    1) Web Workers: Think of it as Hyper-Threading for web browsers. Separate background threads are used to do processing without effecting the performance of a webpage. This can be very useful for web applications which relies on heavy scripts to perform functions (among other things).

    2) Video Element: My favorite HTML 5 features yet. You can embed video without having to rely on third-party proprietary plug-ins or codec. You can embed video code with the same amount of ease as you now embed an image with the ability to manipulate videos and built-in video controls among other things.

    3) Canvas: Canvas element lets you render graphics and images on the fly. An excellent implementation of this element was done by the developers of Mozilla lab project Bespin. Which is an extensible Web Code Editor using Canvas (among other things).

    4) Application caches: The ability to store web apps like email locally and access it without having to connect to the internet or install an external client like Outlook or Thunderbird. Google gears, which helps you access Gmail offline, is an implementation of HTML 5 specifications for Applications Cache (and much more). If you use Google Gears than you are using already using this feature. You can try out an online demonstration of this feature in the form of sticky notes http://htmlfive.appspot.com/static/stickies.html, which saves information to your local DB. Works on Safari 4 and Chrome, FF 3.5 is a bit buggy on this demo.

    5) Geolocation: This API defines location information with high-level interface (GPS) associated with the device hosting the API. Sources of location information includes Global Positioning System (GPS) and network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs. Yes, a big brother feature, but it can only be used if the user gives the application permission to use the information.
