HTML5 Local Storage Example

Creating a local storage example using a To Do list.

First create an HTML file with an unordered list. The unordered list must have the html5 contenteditable=”true” attribute to allow the content to be modified. Also give the UL an ID so it can be targeted.

$(document).ready(function() {
var edit = document.getElementById('editableList');
$(edit).blur(function() {
localStorage.setItem('toDoData', this.innerHTML);
//when the page loads
edit.innerHTML = localStorage.getItem('toDoData');

In the inspector you can deleted the stored data. Note the data is stored per browser.

A Little More About Local Storage

HTML5 storage provides a way for web sites to store information on your computer and retrieve it later. The concept is similar to cookies, but it’s designed for larger quantities of information. Cookies are limited in size, and your browser sends them back to the web server every time it requests a new page (which takes extra time and precious bandwidth). HTML5 storage stays on your computer, and web sites can access it with JavaScript after the page is loaded. –
