Notes: Examples:
1) If unspecified, the month / day defaults to the current month / day, 1991 or
the time defaults to midnight, while the timezone defaults to the 1992-10 or
browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
are optional. 1995-07-18T17:21:28-02:00 or
2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or

* @param {Object} [options] An object containing handler configuration.
*
* **Note:** Unlike in ExtJS 3.x, the options object will also be passed as the last
* argument to every event handler.
*
* This object may contain any of the following properties:
*
* @param {Object} options.scope
* The scope (`this` reference) in which the handler function is executed. **If omitted,
* defaults to the object which fired the event.**
*
* @param {Number} options.delay
* The number of milliseconds to delay the invocation of the handler after the event fires.
*
* @param {Boolean} options.single
* True to add a handler to handle just the next firing of the event, and then remove itself.
*
* @param {Number} options.buffer
* 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.
*
* @param {Ext.util.Observable} options.target
* Only call the handler if the event was fired on the target Observable, _not_ if the event
* was bubbled up from a child Observable.
*
* @param {String} options.element
* **This option is only valid for listeners bound to {@link Ext.Component Components}.**
* The name of a Component property which references an element to add a listener to.
*
* This option is useful during Component construction to add DOM event listeners to elements of
* {@link Ext.Component Components} which will exist only after the Component is rendered.
* For example, to add a click listener to a Panel's body:
*
* new Ext.panel.Panel({
* title: 'The title',
* listeners: {
* click: this.handlePanelClick,
* element: 'body'
* }
* });
*
* @param {Boolean} [options.destroyable=false]
* When specified as `true`, the function returns A `Destroyable` object. An object which implements the `destroy` method which removes all listeners added in this call.
*
* @param {Number} [options.priority]
* An optional numeric priority that determines the order in which event handlers
* are run. Event handlers with no priority will be run as if they had a priority
* of 0. Handlers with a higher priority will be prioritized to run sooner than
* those with a lower priority. Negative numbers can be used to set a priority
* lower than the default. Internally, the framework uses a range of 1000 or
* greater, and -1000 or lesser for handers that are intended to run before or
* after all others, so it is recommended to stay within the range of -999 to 999
* when setting the priority of event handlers in application-level code.
*
* **Combining Options**
*
* Using the options argument, it is possible to combine different types of listeners:
*
* A delayed, one-time listener.
*
* myPanel.on('hide', this.handleClick, this, {
* single: true,
* delay: 100
* });
*
* @return {Object} **Only when the `destroyable` option is specified. **
*
* A `Destroyable` object. An object which implements the `destroy` method which removes all listeners added in this call. For example:
*
* this.btnListeners = = myButton.on({
* destroyable: true
* mouseover: function() { console.log('mouseover'); },
* mouseout: function() { console.log('mouseout'); },
* click: function() { console.log('click'); }
* });
*
* And when those listeners need to be removed:
*
* Ext.destroy(this.btnListeners);
*
* or
*
* this.btnListeners.destroy();

* @class Ext.DomHelper

* @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
*

* dates and defines the Provider interface. By default these methods put the value and the
* type information into a delimited string that can be stored. These should be overridden in
* a subclass if you want to change the format of the encoded value and subsequent decoding. See {@link #stateful} for an explanation of saving and restoring state. An array of events that, when fired, should trigger this object to

/**
* Provides searching of Components within Ext.ComponentManager (globally) or a specific
* Ext.container.Container on the document with a similar syntax to a CSS selector.
* Returns Array of matching Components, or empty Array.
*
* ## Basic Component lookup
*
* Components can be retrieved by using their {@link Ext.Component xtype}:
*
* - `component`
* - `gridpanel`
*
* Matching by `xtype` matches inherited types, so in the following code, the previous field
* *of any type which inherits from `TextField`* will be found:
*
* prevField = myField.previousNode('textfield');
*
* To match only the exact type, pass the "shallow" flag by adding `(true)` to xtype
* (See AbstractComponent's {@link Ext.AbstractComponent#isXType isXType} method):
*
* prevTextField = myField.previousNode('textfield(true)');
*
* You can search Components by their `id` or `itemId` property, prefixed with a #:
*
* #myContainer
*
* Component `xtype` and `id` or `itemId` can be used together to avoid possible
* id collisions between Components of different types:
*
* panel#myPanel
*
* ## Traversing Component tree
*
* Components can be found by their relation to other Components. There are several
* relationship operators, mostly taken from CSS selectors:
*
* - **`E F`** All descendant Components of E that match F
* - **`E > F`** All direct children Components of E that match F
* - **`E ^ F`** All parent Components of E that match F
*
* Expressions between relationship operators are matched left to right, i.e. leftmost
* selector is applied first, then if one or more matches are found, relationship operator
* itself is applied, then next selector expression, etc. It is possible to combine
* relationship operators in complex selectors:
*
* window[title="Input form"] textfield[name=login] ^ form > button[action=submit]
*
* That selector can be read this way: Find a window with title "Input form", in that
* window find a TextField with name "login" at any depth (including subpanels and/or
* FieldSets), then find an `Ext.form.Panel` that is a parent of the TextField, and in
* that form find a direct child that is a button with custom property `action` set to
* value "submit".
*
* Whitespace on both sides of `^` and `>` operators is non-significant, i.e. can be
* omitted, but usually is used for clarity.
*
* ## Searching by Component attributes
*
* Components can be searched by their object property values (attributes). To do that,
* use attribute matching expression in square brackets:
*
* - `component[autoScroll]` - matches any Component that has `autoScroll` property with
* any truthy (non-empty, not `false`) value.
* - `panel[title="Test"]` - matches any Component that has `title` property set to
* "Test". Note that if the value does not contain spaces, the quotes are optional.
*
* Attributes can use any of the operators in {@link Ext.dom.Query DomQuery}'s
* {@link Ext.dom.Query#operators operators} to compare values.
*
* Prefixing the attribute name with an at sign `@` means that the property must be
* the object's `ownProperty`, not a property from the prototype chain.
*
* Specifications like `[propName]` check that the property is a truthy value. To check
* that the object has an `ownProperty` of a certain name, regardless of the value use
* the form `[?propName]`.
*
* The specified value is coerced to match the type of the property found in the
* candidate Component using {@link Ext#coerce}.
*
* If you need to find Components by their `itemId` property, use `#id` form; it will
* do the same but is easier to read.
*
* ## Attribute matching operators
*
* The '=' operator will return the results that **exactly** match the
* specified object property (attribute):
*
* Ext.ComponentQuery.query('panel[cls=my-cls]');
*
* Will match the following Component:
*
* Ext.create('Ext.window.Window', {
* cls: 'my-cls'
* });
*
* But will not match the following Component, because 'my-cls' is one value
* among others:
*
* Ext.create('Ext.panel.Panel', {
* cls: 'foo-cls my-cls bar-cls'
* });
*
* You can use the '~=' operator instead, it will return Components with
* the property that **exactly** matches one of the whitespace-separated
* values. This is also true for properties that only have *one* value:
*
* Ext.ComponentQuery.query('panel[cls~=my-cls]');
*
* Will match both Components:
*
* Ext.create('Ext.panel.Panel', {
* cls: 'foo-cls my-cls bar-cls'
* });
*
* Ext.create('Ext.window.Window', {
* cls: 'my-cls'
* });
*
* Generally, '=' operator is more suited for object properties other than
* CSS classes, while '~=' operator will work best with properties that
* hold lists of whitespace-separated CSS classes.
*
* The '^=' operator will return Components with specified attribute that
* start with the passed value:
*
* Ext.ComponentQuery.query('panel[title^=Sales]');
*
* Will match the following Component:
*
* Ext.create('Ext.panel.Panel', {
* title: 'Sales estimate for Q4'
* });
*
* The '$=' operator will return Components with specified properties that
* end with the passed value:
*
* Ext.ComponentQuery.query('field[fieldLabel$=name]');
*
* Will match the following Component:
*
* Ext.create('Ext.form.field.Text', {
* fieldLabel: 'Enter your name'
* });
*
* The following test will find panels with their `ownProperty` collapsed being equal to
* `false`. It will **not** match a collapsed property from the prototype chain.
*
* Ext.ComponentQuery.query('panel[@collapsed=false]');
*
* Member expressions from candidate Components may be tested. If the expression returns
* a *truthy* value, the candidate Component will be included in the query:
*
* var disabledFields = myFormPanel.query("{isDisabled()}");
*
* Such expressions are executed in Component's context, and the above expression is
* similar to running this snippet for every Component in your application:
*
* if (component.isDisabled()) {
* matches.push(component);
* }
*
* It is important to use only methods that are available in **every** Component instance
* to avoid run time exceptions. If you need to match your Components with a custom
* condition formula, you can augment `Ext.Component` to provide custom matcher that
* will return `false` by default, and override it in your custom classes:
*
* Ext.define('My.Component', {
* override: 'Ext.Component',
* myMatcher: function() { return false; }
* });
*
* Ext.define('My.Panel', {
* extend: 'Ext.panel.Panel',
* requires: ['My.Component'], // Ensure that Component override is applied
* myMatcher: function(selector) {
* return selector === 'myPanel';
* }
* });
*
* After that you can use a selector with your custom matcher to find all instances
* of `My.Panel`:
*
* Ext.ComponentQuery.query("{myMatcher('myPanel')}");
*
* However if you really need to use a custom matcher, you may find it easier to implement
* a custom Pseudo class instead (see below).
*
* ## Conditional matching
*
* Attribute matchers can be combined to select only Components that match **all**
* conditions (logical AND operator):
*
* Ext.ComponentQuery.query('panel[cls~=my-cls][floating=true][title$="sales data"]');
*
* E.g., the query above will match only a Panel-descended Component that has 'my-cls'
* CSS class *and* is floating *and* with a title that ends with "sales data".
*
* Expressions separated with commas will match any Component that satisfies
* *either* expression (logical OR operator):
*
* Ext.ComponentQuery.query('field[fieldLabel^=User], field[fieldLabel*=password]');
*
* E.g., the query above will match any field with field label starting with "User",
* *or* any field that has "password" in its label.
*
* ## Pseudo classes
*
* Pseudo classes may be used to filter results in the same way as in
* {@link Ext.dom.Query}. There are five default pseudo classes:
*
* * `not` Negates a selector.
* * `first` Filters out all except the first matching item for a selector.
* * `last` Filters out all except the last matching item for a selector.
* * `focusable` Filters out all except Components which are currently able to recieve
* focus.
* * `nth-child` Filters Components by ordinal position in the selection.
*
* These pseudo classes can be used with other matchers or without them:
*
* // Select first direct child button in any panel
* Ext.ComponentQuery.query('panel > button:first');
*
* // Select last field in Profile form
* Ext.ComponentQuery.query('form[title=Profile] field:last');
*
* // Find first focusable Component in a panel and focus it
* panel.down(':focusable').focus();
*
* // Select any field that is not hidden in a form
* form.query('field:not(hiddenfield)');
*
* Pseudo class `nth-child` can be used to find any child Component by its
* position relative to its siblings. This class' handler takes one argument
* that specifies the selection formula as `Xn` or `Xn+Y`:
*
* // Find every odd field in a form
* form.query('field:nth-child(2n+1)'); // or use shortcut: :nth-child(odd)
*
* // Find every even field in a form
* form.query('field:nth-child(2n)'); // or use shortcut: :nth-child(even)
*
* // Find every 3rd field in a form
* form.query('field:nth-child(3n)');
*
* Pseudo classes can be combined to further filter the results, e.g., in the
* form example above we can modify the query to exclude hidden fields:
*
* // Find every 3rd non-hidden field in a form
* form.query('field:not(hiddenfield):nth-child(3n)');
*
* Note that when combining pseudo classes, whitespace is significant, i.e.
* there should be no spaces between pseudo classes. This is a common mistake;
* if you accidentally type a space between `field` and `:not`, the query
* will not return any result because it will mean "find *field's children
* Components* that are not hidden fields...".
*
* ## Custom pseudo classes
*
* It is possible to define your own custom pseudo classes. In fact, a
* pseudo class is just a property in `Ext.ComponentQuery.pseudos` object
* that defines pseudo class name (property name) and pseudo class handler
* (property value):
*
* // Function receives array and returns a filtered array.
* Ext.ComponentQuery.pseudos.invalid = function(items) {
* var i = 0, l = items.length, c, result = [];
* for (; i < l; i++) {
* if (!(c = items[i]).isValid()) {
* result.push(c);
* }
* }
* return result;
* };
*
* var invalidFields = myFormPanel.query('field:invalid');
* if (invalidFields.length) {
* invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
* for (var i = 0, l = invalidFields.length; i < l; i++) {
* invalidFields[i].getEl().frame("red");
* }
* }
*
* Pseudo class handlers can be even more flexible, with a selector
* argument used to define the logic:
*
* // Handler receives array of itmes and selector in parentheses
* Ext.ComponentQuery.pseudos.titleRegex = function(components, selector) {
* var i = 0, l = components.length, c, result = [], regex = new RegExp(selector);
* for (; i < l; i++) {
* c = components[i];
* if (c.title && regex.test(c.title)) {
* result.push(c);
* }
* }
* return result;
* }
*
* var salesTabs = tabPanel.query('panel:titleRegex("sales\\s+for\\s+201[123]")');
*
* Be careful when using custom pseudo classes with MVC Controllers: when
* you use a pseudo class in Controller's `control` or `listen` component
* selectors, the pseudo class' handler function will be called very often
* and may slow down your application significantly. A good rule of thumb
* is to always specify Component xtype with the pseudo class so that the
* handlers are only called on Components that you need, and try to make
* the condition checks as cheap in terms of execution time as possible.
* Note how in the example above, handler function checks that Component
* *has* a title first, before running regex test on it.
*
* ## Query examples
*
* Queries return an array of Components. Here are some example queries:
*
* // retrieve all Ext.Panels in the document by xtype
* var panelsArray = Ext.ComponentQuery.query('panel');
*
* // retrieve all Ext.Panels within the container with an id myCt
* var panelsWithinmyCt = Ext.ComponentQuery.query('#myCt panel');
*
* // retrieve all direct children which are Ext.Panels within myCt
* var directChildPanel = Ext.ComponentQuery.query('#myCt > panel');
*
* // retrieve all grids or trees
* var gridsAndTrees = Ext.ComponentQuery.query('gridpanel, treepanel');
*
* // Focus first Component
* myFormPanel.child(':focusable').focus();
*
* // Retrieve every odd text field in a form
* myFormPanel.query('textfield:nth-child(odd)');
*
* // Retrieve every even field in a form, excluding hidden fields
* myFormPanel.query('field:not(hiddenfield):nth-child(even)');
*
* For easy access to queries based from a particular Container see the
* {@link Ext.container.Container#query}, {@link Ext.container.Container#down} and
* {@link Ext.container.Container#child} methods. Also see
* {@link Ext.Component#up}.

* A Container's child Components are rendered by that Container's

* of child items is the responsibility of the Container's {@link Ext.container.Container#layout layout}
* manager. If you expect child items to be sized in response to user interactions, you must
* configure the Container with a layout manager which creates and manages the type of layout you
* have in mind.
