/**
* @class Ext.util.DelayedTask
*
* The DelayedTask class provides a convenient way to "buffer" the execution of a method,
* performing setTimeout where a new timeout cancels the old timeout. When called, the
* task will wait the specified time period before executing. If durng that time period,
* the task is called again, the original call will be cancelled. This continues so that
* the function is only called a single time for each iteration.
*
* This method is especially useful for things like detecting whether a user has finished
* typing in a text field. An example would be performing validation on a keypress. You can
* use this class to buffer the keypress events for a certain number of milliseconds, and
* perform only if they stop for that amount of time.
*
* ## Usage
*
* var task = new Ext.util.DelayedTask(function(){
* alert(Ext.getDom('myInputField').value.length);
* });
*
* // Wait 500ms before calling our function. If the user presses another key
* // during that 500ms, it will be cancelled and we'll wait another 500ms.
* Ext.get('myInputField').on('keypress', function(){
* task.{@link #delay}(500);
* });
*
* Note that we are using a DelayedTask here to illustrate a point. The configuration
* option `buffer` for {@link Ext.util.Observable#addListener addListener/on} will
* also setup a delayed task for you to buffer events.
*
* @constructor The parameters to this constructor serve as defaults and are not required.
* @param {Function} fn (optional) The default function to call. If not specified here, it must be specified during the {@link #delay} call.
* @param {Object} scope (optional) The default scope (The this
reference) in which the
* function is called. If not specified, this
will refer to the browser window.
* @param {Array} args (optional) The default Array of arguments.

/**
* @class Ext.DomHelper
* @extends Ext.dom.Helper
* @alternateClassName Ext.core.DomHelper
* @singleton
*
* The DomHelper class provides a layer of abstraction from DOM and transparently supports creating elements via DOM or
* using HTML fragments. It also has the ability to create HTML fragment templates from your DOM building code.
*
* # DomHelper element specification object
*
* A specification object is used when creating elements. Attributes of this object are assumed to be element
* attributes, except for 4 special attributes:
*
* - **tag** - The tag name of the element.
* - **children** or **cn** - An array of the same kind of element definition objects to be created and appended.
* These can be nested as deep as you want.
* - **cls** - The class attribute of the element. This will end up being either the "class" attribute on a HTML
* fragment or className for a DOM node, depending on whether DomHelper is using fragments or DOM.
* - **html** - The innerHTML for the element.
*
* **NOTE:** For other arbitrary attributes, the value will currently **not** be automatically HTML-escaped prior to
* building the element's HTML string. This means that if your attribute value contains special characters that would
* not normally be allowed in a double-quoted attribute value, you **must** manually HTML-encode it beforehand (see
* {@link Ext.String#htmlEncode}) or risk malformed HTML being created. This behavior may change in a future release.
*
* # Insertion methods
*
* Commonly used insertion methods:
*
* - **{@link #append}**
* - **{@link #insertBefore}**
* - **{@link #insertAfter}**
* - **{@link #overwrite}**
* - **{@link #createTemplate}**
* - **{@link #insertHtml}**
*
* # Example
*
* This is an example, where an unordered list with 3 children items is appended to an existing element with
* id 'my-div':
*
* var dh = Ext.DomHelper; // create shorthand alias
* // specification object
* var spec = {
* id: 'my-ul',
* tag: 'ul',
* cls: 'my-list',
* // append children after creating
* children: [ // may also specify 'cn' instead of 'children'
* {tag: 'li', id: 'item0', html: 'List Item 0'},
* {tag: 'li', id: 'item1', html: 'List Item 1'},
* {tag: 'li', id: 'item2', html: 'List Item 2'}
* ]
* };
* var list = dh.append(
* 'my-div', // the context element 'my-div' can either be the id or the actual node
* spec // the specification object
* );
*
* Element creation specification parameters in this class may also be passed as an Array of specification objects. This
* can be used to insert multiple sibling nodes into an existing container very efficiently. For example, to add more
* list items to the example above:
*
* dh.append('my-ul', [
* {tag: 'li', id: 'item3', html: 'List Item 3'},
* {tag: 'li', id: 'item4', html: 'List Item 4'}
* ]);
*
* # Templating
*
* The real power is in the built-in templating. Instead of creating or appending any elements, {@link #createTemplate}
* returns a Template object which can be used over and over to insert new elements. Revisiting the example above, we
* could utilize templating this time:
*
* // create the node
* var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
* // get template
* var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});
*
* for(var i = 0; i < 5, i++){
* tpl.append(list, [i]); // use template to append to the actual node
* }
*
* An example using a template:
*
* var html = '{2}';
*
* var tpl = new Ext.DomHelper.createTemplate(html);
* tpl.append('blog-roll', ['link1', 'http://www.edspencer.net/', "Ed's Site"]);
* tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin's Site"]);
*
* The same example using named parameters:
*
* var html = '{text}';
*
* var tpl = new Ext.DomHelper.createTemplate(html);
* tpl.append('blog-roll', {
* id: 'link1',
* url: 'http://www.edspencer.net/',
* text: "Ed's Site"
* });
* tpl.append('blog-roll', {
* id: 'link2',
* url: 'http://www.dustindiaz.com/',
* text: "Dustin's Site"
* });
*
* # Compiling Templates
*
* Templates are applied using regular expressions. The performance is great, but if you are adding a bunch of DOM
* elements using the same template, you can increase performance even further by {@link Ext.Template#compile
* "compiling"} the template. The way "{@link Ext.Template#compile compile()}" works is the template is parsed and
* broken up at the different variable points and a dynamic function is created and eval'ed. The generated function
* performs string concatenation of these parts and the passed variables instead of using regular expressions.
*
* var html = '{text}';
*
* var tpl = new Ext.DomHelper.createTemplate(html);
* tpl.compile();
*
* //... use template like normal
*
* # Performance Boost
*
* DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead of DOM can significantly
* boost performance.
*
* Element creation specification parameters may also be strings. If {@link #useDom} is false, then the string is used
* as innerHTML. If {@link #useDom} is true, a string specification results in the creation of a text node. Usage:
*
* Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
*

/**
* @class Ext.dom.Query
* @alternateClassName Ext.DomQuery
* @alternateClassName Ext.core.DomQuery
* @singleton
*
* Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes
* and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
*
* DomQuery supports most of the [CSS3 selectors spec][1], along with some custom selectors and basic XPath.
*
* All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example
* `div.foo:nth-child(odd)[@foo=bar].bar:first` would be a perfectly valid selector. Node filters are processed
* in the order in which they appear, which allows you to optimize your queries for your document structure.
*
* ## Element Selectors:
*
* - **`*`** any element
* - **`E`** an element with the tag E
* - **`E F`** All descendent elements of E that have the tag F
* - **`E > F`** or **E/F** all direct children elements of E that have the tag F
* - **`E + F`** all elements with the tag F that are immediately preceded by an element with the tag E
* - **`E ~ F`** all elements with the tag F that are preceded by a sibling element with the tag E
*
* ## Attribute Selectors:
*
* The use of `@` and quotes are optional. For example, `div[@foo='bar']` is also a valid attribute selector.
*
* - **`E[foo]`** has an attribute "foo"
* - **`E[foo=bar]`** has an attribute "foo" that equals "bar"
* - **`E[foo^=bar]`** has an attribute "foo" that starts with "bar"
* - **`E[foo$=bar]`** has an attribute "foo" that ends with "bar"
* - **`E[foo*=bar]`** has an attribute "foo" that contains the substring "bar"
* - **`E[foo%=2]`** has an attribute "foo" that is evenly divisible by 2
* - **`E[foo!=bar]`** attribute "foo" does not equal "bar"
*
* ## Pseudo Classes:
*
* - **`E:first-child`** E is the first child of its parent
* - **`E:last-child`** E is the last child of its parent
* - **`E:nth-child(_n_)`** E is the _n_th child of its parent (1 based as per the spec)
* - **`E:nth-child(odd)`** E is an odd child of its parent
* - **`E:nth-child(even)`** E is an even child of its parent
* - **`E:only-child`** E is the only child of its parent
* - **`E:checked`** E is an element that is has a checked attribute that is true (e.g. a radio or checkbox)
* - **`E:first`** the first E in the resultset
* - **`E:last`** the last E in the resultset
* - **`E:nth(_n_)`** the _n_th E in the resultset (1 based)
* - **`E:odd`** shortcut for :nth-child(odd)
* - **`E:even`** shortcut for :nth-child(even)
* - **`E:contains(foo)`** E's innerHTML contains the substring "foo"

/**
* @class Ext.dom.Element
* @alternateClassName Ext.Element
* @alternateClassName Ext.core.Element
* @extend Ext.dom.AbstractElement
*
* Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.
*
* All instances of this class inherit the methods of {@link Ext.fx.Anim} making visual effects easily available to all
* DOM elements.
*
* Note that the events documented in this class are not Ext events, they encapsulate browser events. Some older browsers
* may not support the full range of events. Which events are supported is beyond the control of Ext JS.
*
* Usage:
*
* // by id
* var el = Ext.get("my-div");
*
* // by DOM element reference
* var el = Ext.get(myDivElement);
*
* # Animations
*
* When an element is manipulated, by default there is no animation.
*
* var el = Ext.get("my-div");
*
* // no animation
* el.setWidth(100);
*
* Many of the functions for manipulating an element have an optional "animate" parameter. This parameter can be
* specified as boolean (true) for default animation effects.
*
* // default animation
* el.setWidth(100, true);
*
* To configure the effects, an object literal with animation options to use as the Element animation configuration
* object can also be specified. Note that the supported Element animation configuration options are a subset of the
* {@link Ext.fx.Anim} animation options specific to Fx effects. The supported Element animation configuration options
* are:
*
* Option Default Description
* --------- -------- ---------------------------------------------
* {@link Ext.fx.Anim#duration duration} 350 The duration of the animation in milliseconds
* {@link Ext.fx.Anim#easing easing} easeOut The easing method
* {@link Ext.fx.Anim#callback callback} none A function to execute when the anim completes
* {@link Ext.fx.Anim#scope scope} this The scope (this) of the callback function
*
* Usage:
*
* // Element animation options object
* var opt = {
* {@link Ext.fx.Anim#duration duration}: 1000,
* {@link Ext.fx.Anim#easing easing}: 'elasticIn',
* {@link Ext.fx.Anim#callback callback}: this.foo,
* {@link Ext.fx.Anim#scope scope}: this
* };
* // animation with some options set
* el.setWidth(100, opt);
*
* The Element animation object being used for the animation will be set on the options object as "anim", which allows
* you to stop or manipulate the animation. Here is an example:
*
* // using the "anim" property to get the Anim object
* if(opt.anim.isAnimated()){
* opt.anim.stop();
* }
*
* # Composite (Collections of) Elements
*
* For working with collections of Elements, see {@link Ext.CompositeElement}
*
* @constructor
* Creates new Element directly.
* @param {String/HTMLElement} element
* @param {Boolean} [forceNew] By default the constructor checks to see if there is already an instance of this
* element in the cache and if there is it returns the same instance. This will skip that check (useful for extending
* this class).
* @return {Object}

/**
* Appends an event handler to this element.
*
* @param {String} eventName The name of event to handle.
*
* @param {Function} fn The handler function the event invokes. This function is passed the following parameters:
*
* - **evt** : EventObject
*
* The {@link Ext.EventObject EventObject} describing the event.
*
* - **el** : HtmlElement
*
* The DOM element which was the target of the event. Note that this may be filtered by using the delegate option.
*
* - **o** : Object
*
* The options object from the call that setup the listener.
*
* @param {Object} scope (optional) The scope (**this** reference) in which the handler function is executed. **If
* omitted, defaults to this Element.**
*
* @param {Object} options (optional) An object containing handler configuration properties. This may contain any of
* the following properties:
*
* - **scope** Object :
*
* The scope (**this** reference) in which the handler function is executed. **If omitted, defaults to this
* Element.**
*
* - **delegate** String:
*
* A simple selector to filter the target or look for a descendant of the target. See below for additional details.
*
* - **stopEvent** Boolean:
*
* True to stop the event. That is stop propagation, and prevent the default action.
*
* - **preventDefault** Boolean:
*
* True to prevent the default action
*
* - **stopPropagation** Boolean:
*
* True to prevent event propagation
*
* - **normalized** Boolean:
*
* False to pass a browser event to the handler function instead of an Ext.EventObject
*
* - **target** Ext.dom.Element:
*
* Only call the handler if the event was fired on the target Element, _not_ if the event was bubbled up from a
* child node.
*
* - **delay** Number:
*
* The number of milliseconds to delay the invocation of the handler after the event fires.
*
* - **single** Boolean:
*
* True to add a handler to handle just the next firing of the event, and then remove itself.
*
* - **buffer** Number:
*
* Causes the handler to be scheduled to run in an {@link Ext.util.DelayedTask} delayed by the specified number of
* milliseconds. If the event fires again within that time, the original handler is _not_ invoked, but the new
* handler is scheduled in its place.
*
* **Combining Options**
*
* Using the options argument, it is possible to combine different types of listeners:
*
* A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the options
* object. The options object is available as the third parameter in the handler function.
*
* Code:
*
* el.on('click', this.onClick, this, {
* single: true,
* delay: 100,
* stopEvent : true,
* forumId: 4
* });
*
* **Attaching multiple handlers in 1 call**
*
* The method also allows for a single argument to be passed which is a config object containing properties which
* specify multiple handlers.
*
* Code:
*
* el.on({
* 'click' : {
* fn: this.onClick,
* scope: this,
* delay: 100
* },
* 'mouseover' : {
* fn: this.onMouseOver,
* scope: this
* },
* 'mouseout' : {
* fn: this.onMouseOut,
* scope: this
* }
* });
*
* Or a shorthand syntax:
*
* Code:
*
* el.on({
* 'click' : this.onClick,
* 'mouseover' : this.onMouseOver,
* 'mouseout' : this.onMouseOut,
* scope: this
* });
*
* **delegate**
*
* This is a configuration option that you can pass along when registering a handler for an event to assist with
* event delegation. Event delegation is a technique that is used to reduce memory consumption and prevent exposure
* to memory-leaks. By registering an event for a container element as opposed to each element within a container.
* By setting this configuration option to a simple selector, the target element will be filtered to look for a
* descendant of the target. For example:
*
* // using this markup:
*
*
paragraph one
*
paragraph two
*
paragraph three
*
*
* // utilize event delegation to registering just one handler on the container element:
* el = Ext.get('elId');
* el.on(
* 'click',
* function(e,t) {
* // handle click
* console.info(t.id); // 'p2'
* },
* this,
* {
* // filter the target element to be a descendant with the class 'clickable'
* delegate: '.clickable'
* }
* );
*
* @return {Ext.dom.Element} this
