2.2.0a
|
| 35 |
|
|
|

|
| 37 |
|
|
|
| 38 |
|
|
2.2.0
|
| 39 |
|
|
|
| 40 |
|
|
* Added configuration of the library via a YAHOO_config object defined
|
| 41 |
|
|
prior to the reference to the library. Currently it supports a listener
|
| 42 |
|
|
parameter that will execute every time a new module YUI module is loaded.
|
| 43 |
|
|
|
| 44 |
|
|
* Added YAHOO.register & YAHOO.getVersion for version stamping modules.
|
| 45 |
|
|
|
| 46 |
|
|
* Added YAHOO.env which is the home for the information about the loaded
|
| 47 |
|
|
YUI modules, and will host more info later.
|
| 48 |
|
|
|
| 49 |
|
|
* YAHOO.util.Lang was relocated to this package and is now YAHOO.lang.
|
| 50 |
|
|
YAHOO.extend and YAHOO.augment have moved to env (the original
|
| 51 |
|
|
functions still work).

|
0.12.2
|
| 54 |
|
|
|
| 55 |
|
|
* No change
|
| 56 |
|
|
|
| 57 |
|
|
0.12.1
|
| 58 |
|
|
|
| 59 |
|
|
* No change
|
| 60 |
|
|
|
| 61 |
|
|
0.12.0
|
| 62 |
|
|
|
| 63 |
|
|
* Added YAHOO.augment, which copies all or part of the prototype of one
|
| 64 |
|
|
object to another.
|
| 65 |
|
|
|
| 66 |
|
|
* YAHOO.namespace now can create multiple namespaces.
|
| 67 |
|
|
|
| 68 |
|
|
* Added an optional third parameter to YAHOO.extend: overrides. It takes
|
| 69 |
|
|
an object literal of properties/methods to apply to the subclass
|
| 70 |
|
|
prototype, overriding the superclass if present.
|
| 71 |
|
|
|
| 72 |
|
|
0.11.4
|
| 73 |
|
|
|
| 74 |
|
|
* Changed window.YAHOO = window.YAHOO || {} to
|
| 75 |
|
|
if (typeof YAHOO == "undefined") YAHOO = {} because the previous statement
|
| 76 |
|
|
contributed to a memory leak in IE6 when the library was hosted in an
|
| 77 |
|
|
iframe.
|
| 78 |
|
|
|
| 79 |
|
|
0.11.3
|
| 80 |
|
|
|
| 81 |
|
|
* Changed var YAHOO = window.YAHOO || {} to window.YAHOO = window.YAHOO || {}.
|
| 82 |
|
|
This fixes an issue in IE where YAHOO would get overwritten if previously
|
| 83 |
|
|
defined via array notation (window["YAHOO"]).
|
| 84 |
|
|
|
| 85 |
|
|
0.11.0
|
| 86 |
|
|
|
| 87 |
|
|
* Added YAHOO.extend, which provides an easy way to assign the prototype,
|
| 88 |
|
|
constructor, and superclass properties inheritance properties. It also
|
| 89 |
|
|
prevents the constructor of the superclass from being exectuted twice.
|
| 90 |
|
|
|
| 91 |
|
|
0.10.0
|
| 92 |
|
|
|
| 93 |
|
|
* Added YAHOO.log that provides a safe way to plumb logging statements in
|
| 94 |
|
|
code that will work if the logging component isn't available.
