# Class Ext.Element

Package: | Ext
Defined In: | Element.js
Class: | Element
Subclasses: | Layer
Extends: | Object

Represents an Element in the DOM.
Usage:

    var el = Ext.get("my-div");

    // or with getEl
    var el = getEl("my-div");

    // or with a DOM element
    var el = Ext.get(myDivElement);

Using Ext.get() or getEl() instead of calling the constructor directly ensures you get the same object each call instead of constructing a new one.
Animations
Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter should either be a boolean (true) or an object literal with animation options. Note that the supported Element animation options are a subset of the Ext.Fx animation options specific to Fx effects. The Element animation options are:

    Option    Default   Description
    --------- --------  ---------------------------------------------
    duration  .35       The duration of the animation in seconds
    easing    easeOut   The easing method
    callback  none      A function to execute when the anim completes
    scope     this      The scope (this) of the callback function

Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or manipulate the animation. Here's an example:

    var el = Ext.get("my-div");

    // no animation
    el.setWidth(100);

    // default animation
    el.setWidth(100, true);

    // animation with some options set
    el.setWidth(100, {
        duration: 1,
        callback: this.foo,
        scope: this
    });

    // using the "anim" property to get the Anim object
    var opt = {
        duration: 1,
        callback: this.foo,
        scope: this
    };
    el.setWidth(100, opt);
    ...
    if(opt.anim.isAnimated()){
        opt.anim.stop();
    }

## Public Methods

Method | Defined By
--- | ---
| Element( `String/HTMLElement element`, [`Boolean forceNew`] ) Create a new Element directly. Create a new Element directly. Parameters: `element` : String/HTMLElement `forceNew` : Boolean (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). Returns: `` | Element
| Element.fly( `String/HTMLElement el`, [`String named`] ) : Element <static> Gets the globally shared flyweight Element, with the passed node as the active element. Do not store a... <static> Gets the globally shared flyweight Element, with the passed node as the active element. Do not store a reference to this element - the dom node can be overwritten by other code. Parameters: `el` : String/HTMLElement The dom node or id `named` : String (optional) Allows for creation of named reusable flyweights to prevent conflicts (e.g. internally Ext uses "_internal") Returns: `Element` The shared Element object (or null if no matching element was found) | Element
| Element.get( `Mixed el` ) : Element <static> Static method to retrieve Element objects. Uses simple caching to consistently return the same object.... <static> Static method to retrieve Element objects. Uses simple caching to consistently return the same object. Automatically fixes if an object was recreated with the same id via AJAX or DOM. Parameters: `el` : Mixed The id of the node, a DOM Node or an existing Element. Returns: `Element` The Element object (or null if no matching element was found) | Element
| addClass( `String/Array className` ) : Ext.Element Adds one or more CSS classes to the element. Duplicate classes are automatically filtered out. Adds one or more CSS classes to the element. Duplicate classes are automatically filtered out. Parameters: `className` : String/Array The CSS class to add, or an array of classes Returns: `Ext.Element` this | Element
| addClassOnClick( `String className` ) : Ext.Element Sets up event handlers to add and remove a css class when the mouse is down and then up on this element (a click effect) Sets up event handlers to add and remove a css class when the mouse is down and then up on this element (a click effect) Parameters: `className` : String Returns: `Ext.Element` this | Element
| addClassOnFocus( `String className` ) : Ext.Element Sets up event handlers to add and remove a css class when this element has the focus Sets up event handlers to add and remove a css class when this element has the focus Parameters: `className` : String Returns: `Ext.Element` this | Element
| addClassOnOver( `String className`, [`Boolean preventFlicker`] ) : Ext.Element Sets up event handlers to add and remove a css class when the mouse is over this element Sets up event handlers to add and remove a css class when the mouse is over this element Parameters: `className` : String `preventFlicker` : Boolean (optional) If set to true, it prevents flickering by filtering mouseout events for children elements Returns: `Ext.Element` this | Element
| addKeyListener( `Number/Array/Object/String key`, `Function fn`, [`Object scope`] ) : Ext.KeyMap Convenience method for constructing a KeyMap Convenience method for constructing a KeyMap Parameters: `key` : Number/Array/Object/String Either a string with the keys to listen for, the numeric key code, array of key codes or an object with the following options: {key: (number or array), shift: (true/false), ctrl: (true/false), alt: (true/false)} `fn` : Function The function to call `scope` : Object (optional) The scope of the function Returns: `Ext.KeyMap` The KeyMap created | Element
| addKeyMap( `Object config` ) : Ext.KeyMap Creates a KeyMap for this element Creates a KeyMap for this element Parameters: `config` : Object The KeyMap config. See Ext.KeyMap for more details Returns: `Ext.KeyMap` The KeyMap created | Element
- | addListener( `String eventName`, `Function fn`, [`Object scope`], [`Object options`] ) : void Appends an event handler to this element. The shorthand version on is equivalent. Appends an event handler to this element. The shorthand version on is equivalent. Parameters: `eventName` : String The type of event to handle `fn` : Function The handler function the event invokes `scope` : Object (optional) The scope (this element) of the handler function `options` : Object (optional) An object containing handler configuration properties. This may contain any of the following properties: scope {Object} : The scope in which to execute the handler function. The handler function's "this" context. delegate {String} : A simple selector to filter the target or look for a descendant of the target stopEvent {Boolean} : True to stop the event. That is stop propagation, and prevent the default action. preventDefault {Boolean} : True to prevent the default action stopPropagation {Boolean} : True to prevent event propagation normalized {Boolean} : False to pass a browser event to the handler function instead of an Ext.EventObject delay {Number} : The number of milliseconds to delay the invocation of the handler after te event fires. single {Boolean} : True to add a handler to handle just the next firing of the event, and then remove itself. buffer {Number} : Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place. Combining Options In the following examples, the shorthand form 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: A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId) Code:
      el.on('click', this.onClick, this, {
          single: true,
          delay: 100,
          stopEvent : true,
          forumId: 4
      });
  Attaching multiple handlers in 1 call The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers. Code:
      el.on({
          'click' : {
              fn: this.onClick,
              scope: this,
              delay: 100
          },
          'mouseover' : {
              fn: this.onMouseOver,
              scope: this
          },
          'mouseout' : {
              fn: this.onMouseOut,
              scope: this
          }
      });
  Or a shorthand syntax: Code:
      el.on({
          'click' : this.onClick,
          'mouseover' : this.onMouseOver,
          'mouseout' : this.onMouseOut,
          scope: this
      });
Returns: `void` | Element
| alignTo( `Mixed element`, `String position`, [`Array offsets`], [`Boolean/Object animate`] ) : Ext.Element Aligns this element with another element relative to the specified anchor points. If the other element is the documen... Aligns this element with another element relative to the specified anchor points. If the other element is the document it aligns it to the viewport. The position parameter is optional, and can be specified in any one of the following formats: Blank: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl"). One anchor (deprecated): The passed anchor position is used as the target element's anchor point. The element being aligned will position its top-left corner (tl) to that point. This method has been deprecated in favor of the newer two anchor syntax below. Two anchors: If two values from the table below are passed separated by a dash, the first value is used as the element's anchor point, and the second value is used as the target's anchor point. In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than that specified in order to enforce the viewport constraints. Following are all of the supported anchor positions:
    Value  Description
    -----  -----------------------------
    tl     The top left corner (default)
    t      The center of the top edge
    tr     The top right corner
    l      The center of the left edge
    c      In the center of the element
    r      The center of the right edge
