HTML + JavaScript + CSS3+ jQuery
Easy to start• Just <!DOCTYPE html>• No more - <!DOCTYPE HTML PUBLIC
"-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
Self-validation of form elements<input type="email" placeholder="email address"
required />
Make elements editable<div contenteditable>Test</div>
Easier code maintenance• <section>• <header>• <footer>• <article>• <aside>• <nav>
Media<audio controls><source src=“test.mp3" type="audio/mpeg"></audio>
<video width="320" height="240" ><source src="movie.mp4" type="video/mp4"></video>
Web Storage• localStorage["bar"] = foo;• var foo = localStorage["bar"];
a lot of storage space on the client that persists beyond a page refresh and isn’t transmitted to the server
Geolocation• navigator.geolocation.getCurrentPosition(sho
wPosition);• function showPosition(position)
{// position.coords.latitude// position.coords.longitude; }
HTML4• Your old markup works still…
<CANVAS> API• “a resolution-dependent bitmap canvas that
can be used for rendering graphs, games graphics, or other visual images on the fly.”
WEB WORKER• No more long-running scripts which will freeze your browser. Run
your scripts in background.
w=new Worker(“workerfile.js");w.onmessage = function (event) {
document.getElementById("result").innerHTML=event.data;};function stopWorker(){
w.terminate();}
Offline web applications• connect to the Internet• load a web page• disconnect from the Internet• work!
