*
* If an Ajax request follows the _same-origin policy_ **and** its response

*
*
* In other words: you don't even need to provide a callback to leverage

* RJS.

* <h4>Methods you may find useful</h4>
*
*
* Instances of the `Request` object provide several methods that can come in
* handy in your callback functions, especially once the request is complete.
*
*
* <h5>Is the response a successful one?</h5>
*
*
* The [[Ajax.Request#success]] method examines the XHR object's `status`
* property and follows general HTTP guidelines: unknown status is deemed
* successful, as is the whole `2xy` status code family. It's a generally
* better way of testing your response than the usual
* `200 == transport.status`.
*
*
* <h5>Getting HTTP response headers</h5>
*
*
* While you can obtain response headers from the XHR object using its
* `getResponseHeader` method, this makes for verbose code, and several
* implementations raise an exception when the header is not found. To make
* this easier, you can use the [[Ajax.Response#getHeader]] method, which
* delegates to the longer version and returns `null` if an exception occurs:

* <h5>Evaluating JSON headers</h5>

*
* Some backends will return JSON not as response text, but in the `X-JSON`
* header. In this case, you don't even need to evaluate the returned JSON
* yourself, as Prototype automatically does so. It passes the result as the
* `headerJSON` property of the [[Ajax.Response]] object. Note that if there
* is no such header — or its contents are invalid — `headerJSON` will be set

/** section: Ajax
* Ajax.Responders

* A repository of global listeners notified about every step of
* Prototype-based Ajax requests.
*
*
* Sometimes, you need to provide generic behaviors over all Ajax operations
* happening on the page (through [[Ajax.Request]], [[Ajax.Updater]] or
* [[Ajax.PeriodicalUpdater]]).
*
*
* For instance, you might want to automatically show an indicator when an
* Ajax request is ongoing, and hide it when none are. You may well want to
* factor out exception handling as well, logging those somewhere on the page
* in a custom fashion. The possibilities are myriad.
*
*
* To achieve this, Prototype provides `Ajax.Responders`, which lets you
* register (and, if you wish, unregister later) _responders_, which are
* objects with specially-named methods. These names come from a set of
* general callbacks corresponding to different points in time (or outcomes)
* of an Ajax request's life cycle.
*
*
* For instance, Prototype automatically registers a responder that maintains
* a nifty variable: [[Ajax.activeRequestCount]]. This represents, at a given
* time, the number of currently active Ajax requests — by monitoring their
* time, the number of currently active Ajax requests &mdash; by monitoring their
* `onCreate` and `onComplete` events. The code for this is fairly simple:

* evaluating the `X-JSON` response header, if any (can be `null`). They also

* * `evalScripts` ([[Boolean]]; defaults to `false`): Whether `<script>`
* elements in the response text should be evaluated.
* * `insertion` ([[String]]): By default, `Element.update` is used, meaning
* the contents of the response will replace the entire contents of the
* container. You may _instead_ insert the response text without disrupting
* existing contents. The `insertion` option takes one of four strings —
* `top`, `bottom`, `before`, or `after` — and _inserts_ the contents of the
* existing contents. The `insertion` option takes one of four strings &mdash;
* `top`, `bottom`, `before`, or `after` &mdash; and _inserts_ the contents of the
* response in the manner described by [[Element#insert]].
*
*
* <h4>About `evalScripts` and defining functions</h4>
*
*
* If you use `evalScripts: true`, any `<script>` block will be evaluated.
* This **does not** mean it will be evaluated in the global scope. In other
* words:
*
*
* * The evaluation scope will be that of Prototype's internal processing
* function. Anything in your script declared with the `var` keyword will be
* discarded momentarily after evaluation, and will be invisible to any
* other scope.
* * If any `<script>` blocks inside Ajax responses _define functions_, they
* will need to be assigned to properties of the `window` object — _not_
* will need to be assigned to properties of the `window` object &mdash; _not_
* declared with the `function` keyword.
*
*
* For example, this won't work:
*
*
* // This kind of script won't work if processed by Ajax.Updater:
* function coolFunc() {
* // Amazing stuff!
* }
*
*
* Instead, use the following syntax:
*
*
* // This kind of script WILL work if processed by Ajax.Updater:
* coolFunc = function() {
* // Amazing stuff!
* }
*
*
* <h4>Single container, or success/failure split?</h4>
*
* The examples above all assume you’re going to update the same container
*
* The examples above all assume you're going to update the same container
* whether your request succeeds or fails. Instead, you may want to update
* _only_ for successful requests, or update a _different container_ on failed
* requests.
*
*
* To achieve this, you can pass an object instead of a DOM element for the
* `container` parameter. This object _must_ have a `success` property whose
* value identifies the container to be updated on successful requests.
*
*
* If you also provide it with a `failure` property, its value will be used as
* the container for failed requests.
*
*
* In the following code, only successful requests get an update:
*
*
* new Ajax.Updater({ success: 'items' }, '/items', {
* parameters: { text: $F('text') },
* insertion: 'bottom'
* });
*
*
* This next example assumes failed requests will deliver an error message as
* response text — one that should be shown to the user in another area:
*
* new Ajax.Updater({ success: 'items', failure: 'notice' }, '/items',
* response text &mdash; one that should be shown to the user in another area:
*
* new Ajax.Updater({ success: 'items', failure: 'notice' }, '/items',
* parameters: { text: $F('text') },
* insertion: 'bottom'
* });

*
* This is a collection of methods that assist in dealing with form controls.
* They provide ways to focus, serialize, disable/enable or extract current
* value from a specific control.
*
*
* Note that nearly all these methods are available directly on `input`,
* `select`, and `textarea` elements. Therefore, these are equivalent:
*
*
* Form.Element.activate('myfield');
* $('myfield').activate();
*
*
* Naturally, you should always prefer the shortest form suitable in a
* situation. Most of these methods also return the element itself (as
* indicated by the return type) for chainability.

* * It adds quite a few extra methods, which are documented in this section.

* With Prototype, arrays become much, much more than the trivial objects we

*
* Many JavaScript authors have been misled into using the `for...in` JavaScript
* construct to loop over array elements. This kind of code just won't work

*
*
* The ECMA 262 standard, which defines ECMAScript 3rd edition, supposedly
* implemented by all major browsers including MSIE, defines ten methods
* on Array (§15.4.4), including nice methods like `concat`, `join`, `pop`, and
* on Array (&sect;15.4.4), including nice methods like `concat`, `join`, `pop`, and
* `push`.

* This same standard explicitely defines that the `for…in` construct (§12.6.4)
*
* This same standard explicitly defines that the `for...in` construct (&sect;12.6.4)
* exists to enumerate the properties of the object appearing on the right side
* of the `in` keyword. Only properties specifically marked as _non-enumerable_
* are ignored by such a loop. By default, the `prototype` and `length`
* properties are so marked, which prevents you from enumerating over array
* methods when using for…in. This comfort led developers to use `for…in` as a
* methods when using for...in. This comfort led developers to use `for...in` as a
* shortcut for indexing loops, when it is not its actual purpose.
*
*
* However, Prototype has no way to mark the methods it adds to
* `Array.prototype` as non-enumerable. Therefore, using `for…in` on arrays
* `Array.prototype` as non-enumerable. Therefore, using `for...in` on arrays
* when using Prototype will enumerate all extended methods as well, such as
* those coming from the [[Enumerable]] module, and those Prototype puts in the
* Array namespace (listed further below).
*
*
* <h4>What you should use instead</h4>
*
*
* You can revert to vanilla loops:
*
*
* for (var index = 0; index < myArray.length; ++index) {
* var item = myArray[index];
* // Your code working on item here...
* }
*
*
* Or you can use iterators, such as [[Array#each]]:

* // Your code working on item here...
* });
*

*
* The inability to use `for...in` on arrays is not much of a burden: as you'll
* see, most of what you used to loop over arrays for can be concisely done
* using the new methods provided by Array or the mixed-in [[Enumerable]]

*
*
*
*
* <h4>A note on performance</h4>

* ranges from the server side, lazy-loading style). You want to be able to
* mix `Enumerable` in (and we commend you for it). How do you go about this?
*
*
* The Enumerable module basically makes only one requirement on your object:
* it must provide a method named `_each` (note the leading underscore) that
* will accept a function as its unique argument, and will contain the actual
* “raw iteration” algorithm, invoking its argument with each element in turn.

* As detailed in the documentation for [[Enumerable#each]], `Enumerable`
* provides all the extra layers (handling iteration short-circuits, passing
* numeric indices, etc.). You just need to implement the actual iteration,
* as fits your internal structure.
*
*
* If you're still confused, just have a look at the Prototype source code for
* [[Array]], [[Hash]], or [[ObjectRange]]. They all begin with their own
* `_each` method, which should help you grasp the idea.
*
* Once you’re done with this, you just need to mix `Enumerable` in, which
* you’ll usually do before defining your methods, so as to make sure whatever

* Once you're done with this, you just need to mix `Enumerable` in, which
* you'll usually do before defining your methods, so as to make sure whatever
* overrides you provide for `Enumerable` methods will indeed prevail. In
* short, your code will probably end up looking like this:
*
*
*
*
* var YourObject = Class.create(Enumerable, {
* initialize: function() { // with whatever constructor arguments you need
* // Your construction code
* },
*
*
* _each: function(iterator) {
* // Your iteration code, invoking iterator at every turn
* },
*
*
* // Your other methods here, including Enumerable overrides
* });
*
*
* Then, obviously, your object can be used like this:
*
*
* var obj = new YourObject();
* // Populate the collection somehow
* obj.pluck('somePropName');
* obj.invoke('someMethodName');
* obj.size();

/** section: Language
* class Template
*
*
* A class for sophisticated string interpolation.
*
*
* Any time you have a group of similar objects and you need to produce
* formatted output for these objects, maybe inside a loop, you typically
* resort to concatenating string literals with the object's fields:
*
*
* "The TV show " + title + " was created by " + author + ".";
*
*
* There's nothing wrong with this approach, except that it is hard to
* visualize the output immediately just by glancing at the concatenation
* expression. The `Template` class provides a much nicer and clearer way of
* achieving this formatting.
*
*
* <h4>Straightforward templates</h4>
*
*
* The `Template` class uses a basic formatting syntax, similar to what is
* used in Ruby. The templates are created from strings that have embedded
* symbols in the form (e.g., `#{fieldName}`) that will be replaced by
* symbols in the form (e.g., `#{fieldName}`) that will be replaced by
* actual values when the template is applied (evaluated) to an object.
*
*
* // the template (our formatting expression)
* var myTemplate = new Template(
* 'The TV show #{title} was created by #{author}.');
*
*
* // our data to be formatted by the template
* var show = {
* var show = {
* title: 'The Simpsons',
* author: 'Matt Groening',
* network: 'FOX'
* };
*
*
* // let's format our data
* myTemplate.evaluate(show);
* // -> "The TV show The Simpsons was created by Matt Groening."
*
*
* <h4>Templates are meant to be reused</h4>
*
*
* As the example illustrates, `Template` objects are not tied to specific
* data. The data is bound to the template only during the evaluation of the
* template, without affecting the template itself. The next example shows the
* same template being used with a handful of distinct objects.
*
*
* // creating a few similar objects
* var conversion1 = { from: 'meters', to: 'feet', factor: 3.28 };
* var conversion2 = { from: 'kilojoules', to: 'BTUs', factor: 0.9478 };

* <h4>Escape sequence</h4>
*
*
* There's always the chance that one day you'll need to have a literal in your
* template that looks like a symbol, but is not supposed to be replaced. For
* these situations there's an escape character: the backslash (<code>\\</code>).

Version: 0.4
Usage:
Add a script tag for this script and any stylesets you need to use
to the page in question, add correct class names to CODE elements,
define CSS styles for elements. That's it!
Known to work on:
IE 5.5+ PC
Firefox/Mozilla PC/Mac
Opera 7.23 + PC
Safari 2
Known to degrade gracefully on:
IE5.0 PC
Note: IE5.0 fails due to the use of lookahead in some stylesets. To avoid script errors
in older browsers use expressions that use lookahead in string format when defining stylesets.
This script is inspired by star-light by entirely cunning Dean Edwards
