- * @class Ext.DomHelper\r
- * <p>The DomHelper class provides a layer of abstraction from DOM and transparently supports creating\r
- * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates\r
- * from your DOM building code.</p>\r
- *\r
- * <p><b><u>DomHelper element specification object</u></b></p>\r
- * <p>A specification object is used when creating elements. Attributes of this object\r
- * are assumed to be element attributes, except for 4 special attributes:\r
- * <div class="mdetail-params"><ul>\r
- * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li>\r
- * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the\r
- * same kind of element definition objects to be created and appended. These can be nested\r
- * as deep as you want.</div></li>\r
- * <li><b><tt>cls</tt></b> : <div class="sub-desc">The class attribute of the element.\r
- * This will end up being either the "class" attribute on a HTML fragment or className\r
- * for a DOM node, depending on whether DomHelper is using fragments or DOM.</div></li>\r
- * <li><b><tt>html</tt></b> : <div class="sub-desc">The innerHTML for the element</div></li>\r
- * </ul></div></p>\r
- *\r
- * <p><b><u>Insertion methods</u></b></p>\r
- * <p>Commonly used insertion methods:\r
- * <div class="mdetail-params"><ul>\r
- * <li><b><tt>{@link #append}</tt></b> : <div class="sub-desc"></div></li>\r
- * <li><b><tt>{@link #insertBefore}</tt></b> : <div class="sub-desc"></div></li>\r
- * <li><b><tt>{@link #insertAfter}</tt></b> : <div class="sub-desc"></div></li>\r
- * <li><b><tt>{@link #overwrite}</tt></b> : <div class="sub-desc"></div></li>\r
- * <li><b><tt>{@link #createTemplate}</tt></b> : <div class="sub-desc"></div></li>\r
- * <li><b><tt>{@link #insertHtml}</tt></b> : <div class="sub-desc"></div></li>\r
- * </ul></div></p>\r
- *\r
- * <p><b><u>Example</u></b></p>\r
- * <p>This is an example, where an unordered list with 3 children items is appended to an existing\r
- * element with id <tt>'my-div'</tt>:<br>\r
- <pre><code>\r
-var dh = Ext.DomHelper; // create shorthand alias\r
-// specification object\r
-var spec = {\r
- id: 'my-ul',\r
- tag: 'ul',\r
- cls: 'my-list',\r
- // append children after creating\r
- children: [ // may also specify 'cn' instead of 'children'\r
- {tag: 'li', id: 'item0', html: 'List Item 0'},\r
- {tag: 'li', id: 'item1', html: 'List Item 1'},\r
- {tag: 'li', id: 'item2', html: 'List Item 2'}\r
- ]\r
-};\r
-var list = dh.append(\r
- 'my-div', // the context element 'my-div' can either be the id or the actual node\r
- spec // the specification object\r
-);\r
- </code></pre></p>\r
- * <p>Element creation specification parameters in this class may also be passed as an Array of\r
- * specification objects. This can be used to insert multiple sibling nodes into an existing\r
- * container very efficiently. For example, to add more list items to the example above:<pre><code>\r
-dh.append('my-ul', [\r
- {tag: 'li', id: 'item3', html: 'List Item 3'},\r
- {tag: 'li', id: 'item4', html: 'List Item 4'}\r
-]);\r
- * </code></pre></p>\r
- *\r
- * <p><b><u>Templating</u></b></p>\r
- * <p>The real power is in the built-in templating. Instead of creating or appending any elements,\r
- * <tt>{@link #createTemplate}</tt> returns a Template object which can be used over and over to\r
- * insert new elements. Revisiting the example above, we could utilize templating this time:\r
- * <pre><code>\r
-// create the node\r
-var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});\r
-// get template\r
-var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});\r
-\r
-for(var i = 0; i < 5, i++){\r
- tpl.append(list, [i]); // use template to append to the actual node\r
-}\r
- * </code></pre></p>\r
- * <p>An example using a template:<pre><code>\r
-var html = '<a id="{0}" href="{1}" class="nav">{2}</a>';\r
-\r
-var tpl = new Ext.DomHelper.createTemplate(html);\r
-tpl.append('blog-roll', ['link1', 'http://www.jackslocum.com/', "Jack's Site"]);\r
-tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin's Site"]);\r
- * </code></pre></p>\r
- *\r
- * <p>The same example using named parameters:<pre><code>\r
-var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';\r
-\r
-var tpl = new Ext.DomHelper.createTemplate(html);\r
-tpl.append('blog-roll', {\r
- id: 'link1',\r
- url: 'http://www.jackslocum.com/',\r
- text: "Jack's Site"\r
-});\r
-tpl.append('blog-roll', {\r
- id: 'link2',\r
- url: 'http://www.dustindiaz.com/',\r
- text: "Dustin's Site"\r
-});\r
- * </code></pre></p>\r
- *\r
- * <p><b><u>Compiling Templates</u></b></p>\r
- * <p>Templates are applied using regular expressions. The performance is great, but if\r
- * you are adding a bunch of DOM elements using the same template, you can increase\r
- * performance even further by {@link Ext.Template#compile "compiling"} the template.\r
- * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and\r
- * broken up at the different variable points and a dynamic function is created and eval'ed.\r
- * The generated function performs string concatenation of these parts and the passed\r
- * variables instead of using regular expressions.\r
- * <pre><code>\r
-var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';\r
-\r
-var tpl = new Ext.DomHelper.createTemplate(html);\r
-tpl.compile();\r
-\r
-//... use template like normal\r
- * </code></pre></p>\r
- *\r
- * <p><b><u>Performance Boost</u></b></p>\r
- * <p>DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead\r
- * of DOM can significantly boost performance.</p>\r
- * <p>Element creation specification parameters may also be strings. If {@link #useDom} is <tt>false</tt>,\r
- * then the string is used as innerHTML. If {@link #useDom} is <tt>true</tt>, a string specification\r
- * results in the creation of a text node. Usage:</p>\r
- * <pre><code>\r
-Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance\r
- * </code></pre>\r
- * @singleton\r
