It also has the ability to create HTML fragment templates * from your DOM building code.</p> * * <p><b><u>DomHelper element specification object</u></b></p> * <p>A specification object is used when creating elements. Attributes of this object * are assumed to be element attributes, except for 4 special attributes: * <div class="mdetail-params"><ul> * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li> * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the * same kind of element definition objects to be created and appended. These can be nested * as deep as you want.</div></li> * <li><b><tt>cls</tt></b> : <div class="sub-desc">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.</div></li> * <li><b><tt>html</tt></b> : <div class="sub-desc">The innerHTML for the element</div></li> * </ul></div></p> * * <p><b><u>Insertion methods</u></b></p> * <p>Commonly used insertion methods: * <div class="mdetail-params"><ul> * <li><b><tt>{@link #append}</tt></b> : <div class="sub-desc"></div></li> * <li><b><tt>{@link #insertBefore}</tt></b> : <div class="sub-desc"></div></li> * <li><b><tt>{@link #insertAfter}</tt></b> : <div class="sub-desc"></div></li> * <li><b><tt>{@link #overwrite}</tt></b> : <div class="sub-desc"></div></li> * <li><b><tt>{@link #createTemplate}</tt></b> : <div class="sub-desc"></div></li> * <li><b><tt>{@link #insertHtml}</tt></b> : <div class="sub-desc"></div></li> * </ul></div></p> * * <p><b><u>Example</u></b></p> * <p>This is an example, where an unordered list with 3 children items is appended to an existing * element with id <tt>'my-div'</tt>:<br> <pre><code> 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 ); </code></pre></p> * <p>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:<pre><code> dh.append('my-ul', [ {tag: 'li', id: 'item3', html: 'List Item 3'}, {tag: 'li', id: 'item4', html: 'List Item 4'} ]); * </code></pre></p> * * <p><b><u>Templating</u></b></p> * <p>The real power is in the built-in templating. Instead of creating or appending any elements, * <tt>{@link #createTemplate}</tt> 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: * <pre><code> // 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 } * </code></pre></p> * <p>An example using a template:<pre><code> var html = '<a id="{0}" href="{1}" class="nav">{2}</a>'; 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"]); * </code></pre></p> * * <p>The same example using named parameters:<pre><code> var html = '<a id="{id}" href="{url}" class="nav">{text}</a>'; 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" }); * </code></pre></p> * * <p><b><u>Compiling Templates</u></b></p> * <p>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. * <pre><code> var html = '<a id="{id}" href="{url}" class="nav">{text}</a>'; var tpl = new Ext.DomHelper.createTemplate(html); tpl.compile(); //... use template like normal * </code></pre></p> * * <p><b><u>Performance Boost</u></b></p> * <p>DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead * of DOM can significantly boost performance.</p> * <p>Element creation specification parameters may also be strings. If {@link #useDom} is <tt>false</tt>, * then the string is used as innerHTML. If {@link #useDom} is <tt>true</tt>, a string specification * results in the creation of a text node. Usage:</p> * <pre><code> Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance * </code></pre> * @singleton */ Ext.DomHelper = function(){ var tempTableEl = null, emptyTags = /^(?:br|frame|hr|img|input|link|meta|range|spacer|wbr|area|param|col)$/i, tableRe = /^table|tbody|tr|td$/i, pub, // kill repeat to save bytes afterbegin = "afterbegin", afterend = "afterend", beforebegin = "beforebegin", beforeend = "beforeend", ts = '<table>', te = '</table>', tbs = ts+'<tbody>', tbe = '</tbody>'+te, trs = tbs + '<tr>', tre = '</tr>'+tbe; // private function doInsert(el, o, returnElement, pos, sibling, append){ var newNode = pub.insertHtml(pos, Ext.getDom(el), createHtml(o)); return returnElement ?

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.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
<li> <b>*</b> any element</li>
<li> <b>E</b> an element with the tag E</li>
<li> <b>E F</b> All descendent elements of E that have the tag F</li>
<li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
<li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
<li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
</ul>
<h4>Attribute Selectors:</h4>
<p>The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.</p>
<ul class="list">
<li> <b>E[foo]</b> has an attribute "foo"</li>
<li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
<li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
<li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
<li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
<li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
<li> <b>E[foo!=bar]</b> has an attribute "foo" that does not equal "bar"</li>
</ul>
<h4>Pseudo Classes:</h4>
<ul class="list">
<li> <b>E:first-child</b> E is the first child of its parent</li>
<li> <b>E:last-child</b> E is the last child of its parent</li>
<li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
<li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
<li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
<li> <b>E:only-child</b> E is the only child of its parent</li>
<li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
<li> <b>E:first</b> the first E in the resultset</li>
<li> <b>E:last</b> the last E in the resultset</li>
<li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
<li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
<li> <b>E:even</b> shortcut for :nth-child(even)</li>
<li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
<li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
<li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
<li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
<li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>
<li> <b>E:prev(S)</b> an E element whose previous sibling matches simple selector S</li>
</ul>
<h4>CSS Value Selectors:</h4>
<ul class="list">
<li> <b>E{display=none}</b> css value "display" that equals "none"</li>
<li> <b>E{display^=none}</b> css value "display" that starts with "none"</li>
<li> <b>E{display$=none}</b> css value "display" that ends with "none"</li>
<li> <b>E{display*=none}</b> css value "display" that contains the substring "none"</li>
<li> <b>E{display%=2}</b> css value "display" that is evenly divisible by 2</li>
<li> <b>E{display!=none}</b> css value "display" that does not equal "none"</li>
</ul>

* @class Ext.Element
* <p>Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.</p>
* <p>All instances of this class inherit the methods of {@link Ext.Fx} making visual effects easily available to all DOM elements.</p>
* <p>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.</p>
* Usage:<br>
<pre><code>
// by id
var el = Ext.get("my-div");
// by DOM element reference
var el = Ext.get(myDivElement);
</code></pre>
* <b>Animations</b><br />
* <p>When an element is manipulated, by default there is no animation.</p>
* <pre><code>
var el = Ext.get("my-div");
// no animation
el.setWidth(100);
* </code></pre>
* <p>Many of the functions for manipulating an element have an optional "animate" parameter. This
* parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p>
* <pre><code>
// default animation
el.setWidth(100, true);
* </code></pre>
*
* <p>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:</p>
<pre>
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
</pre>
*
* <pre><code>
// 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);
* </code></pre>
* <p>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:</p>
* <pre><code>
// using the "anim" property to get the Anim object
if(opt.anim.isAnimated()){
opt.anim.stop();
}
* </code></pre>
* <p>Also see the <tt>{@link #animate}</tt> method for another animation technique.</p>
* <p><b> Composite (Collections of) Elements</b></p>
* <p>For working with collections of Elements, see {@link Ext.CompositeElement}</p>
* @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 will skip that check (useful for extending this class).

* <li><b>scope</b> Object : <div class="sub-desc">The scope (<code><b>this</b></code> reference) in which the handler function is executed.
* <b>If omitted, defaults to this Element.</b></div></li>
* <li><b>delegate</b> String: <div class="sub-desc">A simple selector to filter the target or look for a descendant of the target. See below for additional details.</div></li>
* <li><b>stopEvent</b> Boolean: <div class="sub-desc">True to stop the event. That is stop propagation, and prevent the default action.</div></li>
* <li><b>preventDefault</b> Boolean: <div class="sub-desc">True to prevent the default action</div></li>
* <li><b>stopPropagation</b> Boolean: <div class="sub-desc">True to prevent event propagation</div></li>

* </ul><br>
* <p>
* <b>Combining Options</b><br>
* In the following examples, the shorthand form {@link #on} is used rather than the more verbose
* addListener. The two are equivalent. Using the options argument, it is possible to combine different
* types of listeners:<br>
* <br>
* 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.<div style="margin: 5px 20px 20px;">
* Code:<pre><code>
el.on('click', this.onClick, this, {
single: true,
delay: 100,
stopEvent : true,
forumId: 4
});</code></pre></p>
* <p>
* <b>Attaching multiple handlers in 1 call</b><br>
* The method also allows for a single argument to be passed which is a config object containing properties
* which specify multiple handlers.</p>
* <p>
* Code:<pre><code>
el.on({
'click' : {
fn: this.onClick,
scope: this,
delay: 100
},
'mouseover' : {
fn: this.onMouseOver,
scope: this
},
'mouseout' : {
fn: this.onMouseOut,
scope: this
}
});</code></pre>
* <p>
* Or a shorthand syntax:<br>
* Code:<pre><code></p>
el.on({
'click' : this.onClick,
'mouseover' : this.onMouseOver,
'mouseout' : this.onMouseOut,
scope: this
});
* </code></pre></p>
* <p><b>delegate</b></p>
* <p>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:<pre><code>
// using this markup:
<div id='elId'>
<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:
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'
}
);
* </code></pre></p>
