Datalist/Details

Form Elements

Custom Data


Local Storage

  • Client-side database
  • Key-value notation (JSON)
  • Stored in users browsers
  • 5 MB (per domain)
  • The data persists
  • After the browser is shutdown or session is closed


window.localStorage.setItem('value', someValue);

Session Storage

  • Just like Local storage but data expires once browser window is closed
    • Still client-side

Indexed Database

WebSQL is deprecated.
IndexedDB is an object store  

var idbRequest = window.indexedDB.open('Database Name');
  idbRequest.onsuccess = function(event) {  
    var db = event.srcElement.result;  
    var transaction = db.transaction([],IDBTransaction.READ_ONLY);  
    var curRequest = transaction.objectStore('Name').openCursor();  
    curRequest.onsuccess = ...;
  }

Application Cache

  • Offline First
  • Cache manifest (*.appcache => file)
  • Load from local cache (HTML, CSS, JS and images)
  • mimetype: text/cache-manifest
  • 5MB (chrome = unlimited storage)
  • window.applicationCache

Webworkers (multi-threading)

App.js

var worker = new Worker(“Thread.js”);
worker.onmessage = function(event) { 
	alert(event.data); 
};
worker.postMessage('data');

Thread.js

self.onmessage = function(event) {  // Do some work.     
  self.postMessage("recv'd:"+event.data);};

Video


<video controls width="500">
  <source src="video.mp4" type="video/mp4" />
  <source src="video.ogg" type="video/ogg" /> 
  <embed src="your_flash_file"

Modernizr (JavaScript)


if (Modernizr.canvas){
  // Create canvas object and get drawing
} else {
  // No canvas support.
}
-------------------------
Modernizr.load({
