* @class Ext.DomHelper
* <p>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.</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

/**
* @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).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>
<p>
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>

* two parameters:</p><div class="mdetail-params"><ul>
* <li><b>c</b> : Array<div class="sub-desc">An Array of DOM elements to filter.</div></li>
* <li><b>v</b> : String<div class="sub-desc">The argument (if any) supplied in the selector.</div></li>
* </ul></div>
* <p>A filter function returns an Array of DOM elements which conform to the pseudo class.</p>
* <p>In addition to the provided pseudo classes listed above such as <code>first-child</code> and <code>nth-child</code>,
* developers may add additional, custom psuedo class filters to select elements according to application-specific requirements.</p>
* <p>For example, to filter <code><a></code> elements to only return links to <i>external</i> resources:</p>
* <code><pre>
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;
};</pre></code>
* Then external links could be gathered with the following statement:<code><pre>
var externalLinks = Ext.select("a:external");
</code></pre>
