When I discovered that Facebook was something more than just a phonebook, however, I soon forgot that the thought ever even crossed my mind.. until today.

I signed into facebook today to start my projects for the day (I’m a facebook developer, mind you) but before I dive right in, I like to check out the facebook stream and see how my friends are doing. I’m quite used to facebook changing things around on me, but when I saw a status that said Facebook was publishing phone numbers, I thought it had to be fake.

Turns out, I find out from a friend that facebook privacy is once again an issue rather than getting a notice from Facebook. All you have to do is go to Account > Edit Friends > PhoneBook and see it for yourself.

Facebook Phonebook Privacy

Considering the fact that they’ve received flack about privacy since day one, you’d think this would be something that they’d take a little bit more seriously and notify users of. What do you think? Is facebook overstepping and shorting us by lack of notice, or do people not care?

I hope that little snippets and code like this will help other developers make more interested and appealing Facebook applications, like we do at Room 214 currently.

First with the styling

#slideWrap creates an extremely wide canvas for the slide to fit on aligned horizontally.
#wrapper then creates a sort of viewport to view the slides through.

<style type="text/css">
#wrapper { clear: left; overflow: hidden; position: relative; width: 520px; }
#slideWrap { clear: both; position: relative; width: 9000px;}
.slide { float: left; width: 520px; }
 
#wrapper #slideNav { float: right; margin: -2.75em 0 2em 0; }
	#slideNav li { display: inline; padding: 0; }
		#slideNav li a {
			background: url(http://cmcilrath.rssready.net/xcel/assets/images/bg_slideNav.png?v=3) no-repeat -12px top;
			display: block;
			float: left;
			height: 12px;
			margin-right: .5em;
			text-decoration: none;
			text-indent: -999em;
			width: 12px;
		}
		#slideNav li a.next, #slideNav li a.prev { width: 10px; }
		#slideNav li a.selected { color: #000; background-position: -12px bottom; }
 
		#slideNav li#prevSlide a { background-position: top left; }
		#slideNav li#prevSlide a.disabled { background-position: bottom left; }
 
		#slideNav li#nextSlide a { background-position: top right; }
		#slideNav li#nextSlide a.disabled { background-position: bottom right; }
</style>

The FBJS script

<script>

FBML Markup

Simple markup here, slideNav controls the slide with onclicks, the JS does the magic.

<div id="wrapper">
	<h2>Header</h2>
	<ul id="slideNav">
		<li id="prevSlide"><a href="#" class="prev disabled">&lt; previous slide</a></li>
		<li><a href="#" id="slideNav-1" onclick="showSlide(1); return false;" class="selected">1</a></li>
		<li><a href="#" id="slideNav-2" onclick="showSlide(2); return false;">2</a></li>
		<li><a href="#" id="slideNav-3" onclick="showSlide(3); return false;">3</a></li>
		<li><a href="#" id="slideNav-4" onclick="showSlide(4); return false;">4</a></li>
		<li><a href="#" id="slideNav-5" onclick="showSlide(5); return false;">5</a></li>
		<li id="nextSlide"><a href="#" class="next" onclick="nextSlide(); return false;">&gt;</a></li>
	</ul>
	<div id="slideWrap">

My confidence what short-lived however, once I discovered that Facebook had a very restricting framework and cache system that would make JS programming something quite a bit less desirable than awesome frameworks like jQuery or Prototype

What you CAN’T do in FBJS

I learned very quickly, that Facebook JavaScript does not allow some very common native functions such as onload, arrays and alerts as well as access to many properties of the document or window level of the DOM. There are workarounds and alternative methods that you can use instead:

window.onload in FBJS

Instead of using window.onload to initialize your functions, use setTimeout.

setTimeout( function(){  }, 10 );

Even an empty setTimout at the beginning of your script will kick start your functions which would normally auto init (this seems to work fine in canvas, but not so much in tabs).

alert alternative for FBJS

Since you can’t use alert or document.write, use Facebook’s dialog box:

new Dialog().showMessage('Dialog', 'This is text');

document.write alternative for FBJS

Since you don’t have access to the document or window levels of the DOM, you’ll want to setup a little include for testing. I drop in this code when i want to quickly output:

<script>
function logOutput(){
    var text = "This will be inserted into my log div";
    document.getElementById('log').setTextValue(text);
}
</script>
<div id="log"></div>

Trouble with JS Arrays in Facebook

For whatever reason, facebook also decided to rip out support for creating objects which also eliminated the way most of us make arrays:

// new Array() is not supported in FBJS
var myarray = [];
myarray[0] = 'stuff';
 
// or
myarray['foo'] = 'bar';
 
// or 
myarray.push('another example');

More to come as I wrestle further with Facebook. Any tips or comments are greatly appreciated!
