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: - *
Insertion methods
- *Commonly used insertion methods: - *
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.jackslocum.com/', "Jack'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.jackslocum.com/',
- text: "Jack'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.DomQuery
-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, 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. -
-The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.
-Object hash of "pseudo class" filter functions which are used when filtering selections. Each function is passed - * two parameters:
A filter function returns an Array of DOM elements which conform to the pseudo class.
- *In addition to the provided pseudo classes listed above such as first-child and nth-child,
- * developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.
For example, to filter <a> elements to only return links to external resources:
-Ext.DomQuery.pseudos.external = function(c, v){
- var r = [], ri = -1;
- for(var i = 0, ci; ci = c[i]; i++){
-// Include in result set only if it's a link to an external resource
- if(ci.hostname != location.hostname){
- r[++ri] = ci;
- }
- }
- return r;

+
+DomQuery supports most of the CSS3 selectors spec, 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$=bar] has an attribute "foo" that ends with "bar"
+ - E[foo*=bar] has an attribute "foo" that contains the substring "bar"
+ - E[foo%=2] has an attribute "foo" that is evenly divisible by 2
+ - E[foo!=bar] has an attribute "foo" that does not equal "bar"
+
+Pseudo Classes:
+
+ - E:first-child E is the first child of its parent
+ - E:last-child E is the last child of its parent
+ - E:nth-child(n) E is the nth child of its parent (1 based as per the spec)
+ - E:nth-child(odd) E is an odd child of its parent
+ - E:nth-child(even) E is an even child of its parent
+ - E:only-child E is the only child of its parent
+ - E:checked E is an element that is has a checked attribute that is true (e.g. a radio or checkbox)
+ - E:first the first E in the resultset
+ - E:last the last E in the resultset
+ - E:nth(n) the nth E in the resultset (1 based)
+ - E:odd shortcut for :nth-child(odd)
+ - E:even shortcut for :nth-child(even)
+ - E:contains(foo) E's innerHTML contains the substring "foo"
+ - E:nodeValue(foo) E contains a textNode with a nodeValue that equals "foo"
+ - E:not(S) an E element that does not match simple selector S
+ - E:has(S) an E element that has a descendent that matches simple selector S
+ - E:next(S) an E element whose next sibling matches simple selector S
+ - E:prev(S) an E element whose previous sibling matches simple selector S
+ - E:any(S1|S2|S2) an E element which matches any of the simple selectors S1, S2 or S3//\\
+
+CSS Value Selectors:
+
+ - E{display=none} css value "display" that equals "none"
+ - E{display^=none} css value "display" that starts with "none"
+ - E{display$=none} css value "display" that ends with "none"

+ * @class Ext.Element
+ * 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} 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. To + * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older + * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.
+ * Usage:
+// by id
+var el = Ext.get("my-div");
+
+// by DOM element reference
+var el = Ext.get(myDivElement);
+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} animation options specific to Fx effects. The supported + * Element animation configuration options are:
+
+Option Default Description
+--------- -------- ---------------------------------------------
+{@link Ext.Fx#duration duration} .35 The duration of the animation in seconds
+{@link Ext.Fx#easing easing} easeOut The easing method
+{@link Ext.Fx#callback callback} none A function to execute when the anim completes
+{@link Ext.Fx#scope scope} this The scope (this) of the callback function
+
+ *
+ *
+// Element animation options object
+var opt = {
+ {@link Ext.Fx#duration duration}: 1,
+ {@link Ext.Fx#easing easing}: 'elasticIn',
+ {@link Ext.Fx#callback callback}: this.foo,
+ {@link Ext.Fx#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();
+}
+ * Also see the {@link #animate} method for another animation technique.
+ *Composite (Collections of) Elements
+ *For working with collections of Elements, see {@link Ext.CompositeElement}
+ * @constructor Create a new Element directly. + * @param {String/HTMLElement} element + * @param {Boolean} forceNew (optional) 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 is a configuration option that you can pass along when registering a handler for + * an event to assist with event delegation.

+ <p id='p1'>paragraph one</p>
+ <p id='p2' class='clickable'>paragraph two</p>
+ <p id='p3'>paragraph three</p>
+</div>
+// utilize event delegation to registering just one handler on the container element:

+
+/**
+ * @class Ext.Fx
+ * A class to provide basic animation and visual effects support. Note: This class is automatically applied + * to the {@link Ext.Element} interface when included, so all effects calls should be performed via {@link Ext.Element}. + * Conversely, since the effects are not actually defined in {@link Ext.Element}, Ext.Fx must be + * {@link Ext#enableFx included} in order for the Element effects to work.
Method Chaining
+ *It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that + * they return the Element object itself as the method return value, it is not always possible to mix the two in a single + * method chain. The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced. + * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately. For this reason, + * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the + * expected results and should be done with care. Also see {@link #callback}.
Anchor Options for Motion Effects
+ *Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element + * that will serve as either the start or end point of the animation. Following are all of the supported anchor positions:
++Value Description +----- ----------------------------- +tl The top left corner +t The center of the top edge +tr The top right corner +l The center of the left edge +r The center of the right edge +bl The bottom left corner +b The center of the bottom edge +br The bottom right corner ++ * Note: some Fx methods accept specific custom config parameters. The options shown in the Config Options + * section below are common options that can be passed to any Fx method unless otherwise noted. + * + * @cfg {Function} callback A function called when the effect is finished. Note that effects are queued internally by the + * Fx class, so a callback is not required to specify another effect -- effects can simply be chained together + * and called in sequence (see note for Method Chaining above), for example:
+ * el.slideIn().highlight();
+ * this reference) in which the {@link #callback} function is executed. Defaults to the browser window.
+ *
+ * @cfg {String} easing A valid Ext.lib.Easing value for the effect:
