YUI Debugging Logger Control Flickr Feed Drag Drop Tutorial
Today we add a Javascript YUI library Debugging Logger Control to build on our previous relevant YUI and jQuery Javascript Flickr Feed Drag and Drop Tutorial as shown below. This Logger Control can be used to gather debugging information you need to display, especially useful with Ajax coding scenarios.
In that previous tutorial we noted that web browser users really like to make use of data feeds and one of the protocol formats they are often using when accessing RSS feeds is JSON (and XML), as outlined below in a Wikipedia entry. In this tutorial we see JavaScript jQuery library functionality accessing the Flickr image hosting share area used by this domain here at rjmprogramming.com.au and then go on to show you YUI library animation Drag and Drop functionality to dynamically rearrange the photographs.
JSON (pron.: /ˈdʒeɪsɒn/ JAY-sawn, pron.: /ˈdʒeɪsən/ JAY-sun), or JavaScript Object Notation, is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for many languages.
The JSON format was originally specified by Douglas Crockford, and is described in RFC 4627. The official Internet media type for JSON is application/json. The JSON filename extension is .json.
The JSON format is often used for serializing and transmitting structured data over a network connection. It is used primarily to transmit data between a server and web application, serving as an alternative to XML.

Did you know …
JavaScript makes a great easy-access Calculator?
Try typing the lines below into the address bar of your favourite browser:
Javascript: eval(512 / 380);
Javascript: eval(512 * 380);
Javascript: eval(512 – 380);
Javascript: eval(512 + 380);
Javascript: eval(512 % 380);
These days we spend so much time on the Internet it is a much quicker way to get to a calculator!
