Class Ext.Element
| Package: | Ext |
| Defined In: | Element.js |
| Class: | Element |
| Subclasses: | Layer |
| Extends: | Object |
Represents an Element in the DOM.
Usage:
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:
For working with collections of Elements, see Ext.CompositeElement
Usage:
// by id
var
el = Ext.get("my-div"
);
// by DOM element reference
var
el = Ext.get(myDivElement);
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 functionAlso, 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();
}
