  • Canvas• canvas is a rectangular area on an HTML page, and it is specified with the <canvas> element. var c=document.getElementById("myCanvas"); var ctx=c.getContext("2d"); var img=document.getElementById("scream"); ctx.drawImage(img,10,10);• To get canvas reference visit this link http://www.w3schools.com/tags/ref_canvas.asp
  • Geo Location• The HTML5 Geo location API is used to get the geographical position of a user.• We user the navigator object to get current position of the application.• To get more information visit http://www.w3schools.com/html/html5_geolocatio n.asp navigator.geolocation.getCurrentPosition(showPosition); navigator.geolocation.watchPosition(showPosition);
  • Video Element1) HTML5 defines a new element which specifies a standard way to embed a video/movie on a web page: the <video> element. Browser MP4 WebM Ogg Internet YES NO NO Explorer 9+ Chrome 6+ YES YES YES Firefox 3.6+ NO YES YES Safari 5+ YES NO NO Opera 10.6+ NO YES YES

  • Web StorageWith HTML5, web pages can store data locallywithin the users browser.Earlier, this was done with cookies. However, WebStorage is more secure and faster. The data is notincluded with every server request, but usedONLY when asked for. It is also possible to storelarge amounts of data, without affecting thewebsites performance.The data is stored in key/value pairs, and a webpage can only access data stored by itself.
  • Application Cache1. HTML5 introduces application cache, which means that a web application is cached, and accessible without an internet connection.2. Application cache gives an application three advantages: 1. Offline browsing - users can use the application when theyre offline 2. Speed - cached resources load faster 3. Reduced server load - the browser will only download updated/changed resources from the server3. To enable application cache, include the manifest attribute in the documents <html> tag.
  • Server Sent Events1. A server-sent event is when a web page automatically gets updates from a server.2. This was also possible before, but the web page would have to ask if any updates were available. With server-sent events, the updates come automatically.3. Examples: Facebook/Twitter updates, stock price updates, news feeds, sport results, etc.4. The EventSource object is used to receive server- sent event notifications5. Each time an update is received, the onmessage event occurs
  • Web Workers1. When executing scripts in an HTML page, the page becomes unresponsive until the script is finished.2. A web worker is a JavaScript that runs in the background, independently of other scripts, without affecting the performance of the page. You can continue to do whatever you want: clicking, selecting things, etc., while the web worker runs in the background.
