/** * @class Ext.util.DelayedTask * <p> The DelayedTask class provides a convenient way to "buffer" the execution of a method, * performing setTimeout where a new timeout cancels the old timeout. When called, the * task will wait the specified time period before executing. If durng that time period, * the task is called again, the original call will be cancelled. This continues so that * the function is only called a single time for each iteration.</p> * <p>This method is especially useful for things like detecting whether a user has finished * typing in a text field. An example would be performing validation on a keypress. You can * use this class to buffer the keypress events for a certain number of milliseconds, and * perform only if they stop for that amount of time. Usage:</p><pre><code> var task = new Ext.util.DelayedTask(function(){ alert(Ext.getDom('myInputField').value.length); }); // Wait 500ms before calling our function. If the user presses another key // during that 500ms, it will be cancelled and we'll wait another 500ms. Ext.get('myInputField').on('keypress', function(){ task.{@link #delay}(500); }); * </code></pre> * <p>Note that we are using a DelayedTask here to illustrate a point. The configuration * option <tt>buffer</tt> for {@link Ext.util.Observable#addListener addListener/on} will * also setup a delayed task for you to buffer events.</p> * @constructor The parameters to this constructor serve as defaults and are not required. * @param {Function} fn (optional) The default function to call. * @param {Object} scope The default scope (The <code><b>this</b></code> reference) in which the * function is called.

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.</p> * Usage:<br> <pre><code> // by id var el = Ext.get("my-div"); // by DOM element reference var el = Ext.get(myDivElement); </code></pre> * <b>Animations</b><br /> * <p>When an element is manipulated, by default there is no animation.</p> * <pre><code> var el = Ext.get("my-div"); // no animation el.setWidth(100); * </code></pre> * <p>Many of the functions for manipulating an element have an optional "animate" parameter. This * parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p> * <pre><code> // default animation el.setWidth(100, true); * </code></pre> * * <p>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} animation options specific to Fx effects. The supported * Element animation configuration options are:</p> <pre> Option Default Description --------- -------- --------------------------------------------- {@link Ext.Fx#duration duration} .35 The duration of the animation in seconds {@link Ext.Fx#easing easing} easeOut The easing method {@link Ext.Fx#callback callback} none A function to execute when the anim completes {@link Ext.Fx#scope scope} this The scope (this) of the callback function </pre> * * <pre><code> // Element animation options object var opt = { {@link Ext.Fx#duration duration}: 1, {@link Ext.Fx#easing easing}: 'elasticIn', {@link Ext.Fx#callback callback}: this.foo, {@link Ext.Fx#scope scope}: this }; // animation with some options set el.setWidth(100, opt); * </code></pre> * <p>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:</p> * <pre><code> // using the "anim" property to get the Anim object if(opt.anim.isAnimated()){ opt.anim.stop(); } * </code></pre> * <p>Also see the <tt>{@link #animate}</tt> method for another animation technique.</p> * <p><b> Composite (Collections of) Elements</b></p> * <p>For working with collections of Elements, see {@link Ext.CompositeElement}</p> * @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.
