/** - * @class Ext.DomHelper - *

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
- * 
- * @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 = '', - te = '
