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.core.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.core.DomHelper.createTemplate(html);
+tpl.append('blog-roll', ['link1', 'http://www.edspencer.net/', "Ed'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.core.DomHelper.createTemplate(html);
+tpl.append('blog-roll', {
+ id: 'link1',
+ url: 'http://www.edspencer.net/',
+ text: "Ed'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.core.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.core.DomHelper.useDom = true; // force it to use DOM; reduces performance
+ * +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.
+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.Anim} 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.Anim} animation options specific to Fx effects. The supported + * Element animation configuration options are:
+
+Option Default Description
+--------- -------- ---------------------------------------------
+{@link Ext.fx.Anim#duration duration} .35 The duration of the animation in seconds
+{@link Ext.fx.Anim#easing easing} easeOut The easing method
+{@link Ext.fx.Anim#callback callback} none A function to execute when the anim completes
+{@link Ext.fx.Anim#scope scope} this The scope (this) of the callback function
+
+ *
+ *
+// Element animation options object
+var opt = {
+ {@link Ext.fx.Anim#duration duration}: 1,
+ {@link Ext.fx.Anim#easing easing}: 'elasticIn',
+ {@link Ext.fx.Anim#callback callback}: this.foo,
+ {@link Ext.fx.Anim#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 will skip that check (useful for extending this class). + */ + (function() { + var DOC = document, + EC = Ext.cache; + + Ext.Element = Ext.core.Element = function(element, forceNew) { + var dom = typeof element == "string" ?
