The second example uses a function literal (or anonymous function): a special, flexible syntax for creating a new function. Just like strings (quotation marks), arrays (brackets), objects (braces), and regular expressions (forward slashes), functions have a literal notation. (Notice also how the second example ends with a semicolon after the closing brace, since the braces aren t a control structure like they are in the first example.) Prototype uses function literals all over the place. You ll see them passed as arguments into methods for working with collections. You ll see them used as callbacks for Ajax requests. You ll see them used to define methods on objects.

This includes the default list of JavaScript files, which includes Prototype by default. Because the Flash Object plug-in adds itself to the list of defaults, this line also includes the Flash Object plug-in for you.

Now, let s put together the main page of our application. Open index.rhtml in /app/views/ today (this file was created when we generated our controller) and add the following content to it: <div id="primary"> <div id="add_task"> </div> <div id='main'> <h1>Today's Tasks</h1> <ul id="todo-list"> <li>test</li> <li>test2</li> </ul> </div> </div> <div id='sidebar'> <div class="sidebar-tasks"> <h1>Overdue Tasks</h1> </div> <div class="sidebar-tasks"> <h1>Due Today </h1> </div> <div class="sidebar-tasks"> <h1>Upcoming Tasks</h1> </div> </div>

The Document Object Model (DOM), an interaction model defined by an ambitious and far-reaching set of W3C specifications, lays out the ideal set of objects, methods, and properties to change an HTML or XML document programmatically. The segmentation of the DOM into many different levels and modules means that the browsers you write code for will have wildly varying levels of DOM support. There are four major implementations of JavaScript and the DOM: Mozilla s SpiderMonkey, Internet Explorer s JScript, Opera s linear_b, and Safari s JavaScriptCore. While each has its strengths and weaknesses, you will discover very quickly that they are not created equal.

s Note You need Prototype, as it s used later in this example. However, if you need to include Flash Object

Fire up a web browser, and navigate to http://localhost:3000/, and you should see something similar to Figure 3-3:

Most developers have the luxury of writing code toward one target: a compiler or canonical interpreter that implements the given language perfectly. Writing JavaScript for modern browsers will make you realize how much this luxury is taken for granted. It can be an excruciating, wailing-and-teeth-grinding experience. Most of these pains will come not from the language itself, but from what other languages would call the standard library the APIs we have that connect JavaScript to a web environment. One nagging pain, for instance, comes from the different levels of DOM support. Let s call these capabilities. They re things that some browsers can do, but that others cannot. A sharper, more chronic pain comes from outright incompatibilities between browsers. The most notable is between Internet Explorer and all other browsers. In all modern versions of Internet Explorer (currently versions 6 and 7), DOM support is minimal; the gaps are filled in by Internet Explorer s legacy API, which predates the DOM. The most agonizing pain, akin to a daily kick in the stomach, comes from what I ll call quirks. Quirks are a diplomatic term for bugs: misimplementations of the DOM spec, memory leaks, and other irrational behavior. These are the largest obstacles to

Next, let s examine the config/routes.rb file (Listing 5-10), which controls the URLs for the entire application:

developer happiness; they re hard to diagnose and hard to work around. They ll leave you staring at your monitor past midnight, bleary eyed and out of ideas. JavaScript frameworks exist to smooth out these cracks. Wherever possible, Prototype provides a unified API that handles all the ugliness under the hood. Prototype won t solve all your problems, but it can definitely make the process of writing JavaScript far less unpleasant.

Figure 3-3. Our page with content added to the view Within a few minutes, we ve created a basic HTML mock-up of our site, which gives us a decent looking interface to use while we build our application (decent being a relative term, of course).
