31 var el = Roo.get("my-div");
34 var el = getEl("my-div");
36 // or with a DOM element

39 * Using Roo.get() or getEl() instead of calling the constructor directly ensures you get the same object
40 * each call instead of constructing a new one.<br><br>
41 * <b>Animations</b><br />
42 * Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter
43 * should either be a boolean (true) or an object literal with animation options. The animation options are:
45 Option Default Description
46 --------- -------- ---------------------------------------------
47 duration .35 The duration of the animation in seconds
48 easing easeOut The YUI easing method
49 callback none A function to execute when the anim completes
50 scope this The scope (this) of the callback function
52 * Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or
53 * manipulate the animation. Here's an example:
55 var el = Roo.get("my-div");
61 el.setWidth(100, true);
63 // animation with some options set
70 // using the "anim" property to get the Anim object
76 el.setWidth(100, opt);

1711 * The position parameter is optional, and can be specified in any one of the following formats:
1713 * <li><b>Blank</b>: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").</li>
1714 * <li><b>One anchor (deprecated)</b>: The passed anchor position is used as the target element's anchor point.
1715 * The element being aligned will position its top-left corner (tl) to that point. <i>This method has been
1716 * deprecated in favor of the newer two anchor syntax below</i>.</li>

1718 * element's anchor point, and the second value is used as the target's anchor point.</li>
1720 * In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of

1722 * the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than
