If you’re unfamiliar with the idea of “unit testing”, don’t worry. It’s not too difficult to understand:

In computer programming, unit testing is a software verification and validation method in which a programmer tests if individual units of source code are fit for use. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual function or procedure.

This is quoted from Wikipedia. Simply put, you write tests for each functionality of your code, and if all of these tests are passed, you can be sure that the code will be bug-free (mostly, depends on how thorough your tests are).

It is due to this allan jardine put together a Javascript bookmarklet called Visual Event which visually shows the elements on a page that have events subscribed to them, what those events are and the function that the event would run when triggered. This is primarily intended to assist debugging, but it can also be very interesting and informative to see the subscribed events on other pages.

If you’re a web developer who wants to build mobile applications in HTML and JavaScript while still taking advantage of the core features in the iPhone, Android and Blackberry SDKs, PhoneGap is for you.

Supported Features

PhoneGap aims to solve device integration by web enabling devices native functionality with open standards.

Above all its totally an open source, hurray…

Here is what the creators of PhoneGap say:

The impression of a three dimensional cube can be created using modern CSS techniques, without the need for JavaScript, imagery, canvas or SVG. Supported in recent WebKit and Gecko based browsers, most importantly Firefox 3.5+ -moz-transform and Safari 3.2+ -webkit-transform.

Briggs has developed an application that chooses the Framework for you.

http://www.athenz.com/app/decision/center/ajax

A collaborative decision platform that is designed to help you make better technology decisions.

A sophisticated, yet friendly decision engine to help you prioritize, compare, assess, and synthesize.

See Demo

Client-side demo works best in Safari or iPhone Safari. Also works Firefox 3 on Windows and Opera. IE support on the way.
Server-side should work anywhere. Examples soon.

for each in:

JavaScript 1.6 added the Array.forEach method:

JAVASCRIPT:

1. [1, 2, 3].forEach(function(item) { alert(item) });

JavaScript 1.7 added array comprehensions for array initialization:

JAVASCRIPT:

1. var squares = [item * item for each (item in [1, 2, 3])];

I just realized I can (ab)use comprehensions to iterate arrays with Perl-like syntax by throwing away the result:

JAVASCRIPT:

1. [alert(item) for each (item in [1, 2, 3])];

I can iterate object properties the same way:

JAVASCRIPT:

1. var obj = { foo: 1, bar: 2, baz: 3 };
2. [alert(name + "=" + obj[name]) for (name in obj)];

Edward Lee points out how to use Iterators:

JAVASCRIPT:

1. [alert(key + "=" + val) for ([key, val] in Iterator({a:1,b:2,c:3}))]

Problem
The Problem JQuery uses a “$” as a shortcut for “jQuery” and Prototype uses “$” as well. We can’t have JQuery and Prototype using the same “$” namespace.

The Fix
Thankfully JQuery has a neat little function called jQuery.noConflict( ) which you basically just need to stick at the top of your JQuery file and replace the “$” alias with “jQuery” for each function. Example:

jQuery.noConflict();
// Do something with jQuery
jQuery(“div p”).hide();
// Do something with another library’s $()
$(“content”).style.display = ‘none’;

Of course, there are other ways of solving this issue with jQuery.noConflict( )

NOTE: JQuery doesn’t get along with MooTools and YUI very well either, luckily this can also be solved with the jQuery.noConflict( ) trick.

Every time i wrote a javascript code i have to check whether its working on different browsers or not, but thses libraries came and saved me from doing all those difficult work.

Here i had a requirement of parsing a JSON with jQuery for my project, i had no idea whatsoever about doing this, but ultimately this article saved me, i really thank him for the code. Here i will tell you people how to do that.

Here is the JSON object that we will be parsing.

Here is the JSON parser that will parse the JSON object.
this parser uses $.getJSON() method, with a call to the JSON object file, and a function to pass the data through for parsing.The common $.each() method in jQuery can be used to traverse the “nodes” (keys) that you indicate.

At first glance it seems I could have refined each reference to a self-invoking function into a single function call. However, you must consider that grabbing data from XML is quite different than grabbing data from JSON. While there is still a parent/child relationship, a child in JSON could be a different type, like an array. There might be several arrays throughout the structure. Simply using the dot operator becomes impossible, and getting different keys can be a unique process.

Each key in jJSON references another hash object with two keys, called values and count. Accessing values will return an array of values, and count will tell you how many of that particular reference exists. For example, how many “title”or “email” key references were obtained from the JSON.

var jJSON = {
    getValues: function(obj,num) {
        return jJSON[obj]["values"].slice(0,((num == null) ? jJSON[obj]["values"].length : num));
    },
    getCount: function(obj) {
        return jJSON[obj]["count"];
    },
    getRandomValues: function(obj,num) {
        var a = [];
        var b = jJSON[obj]["values"];
        var c = b.length;
        if (num != null && num < c) {
            c = num;
        }
        for (i = 0; i < c; i++) {
            var e = Math.floor(Math.random() * b.length);
            a[i] = b[e];
            b.splice(e,1);
        }
        return a;
    }
};

Along with the key references added to the jJSON object, there are three helper methods. The getValues method will return a number of values for a given object key as an array. If you pass in null as the second parameter, you will receive all values. The getCount method will return a count for a given object key. Finally, the getRandomValues will return a number of randomized values for a given object key.
