/**
|
|
|
24 |
The YUI global namespace object. This is the constructor for all YUI instances.
|
|
|
25 |
|
|
|
26 |
This is a self-instantiable factory function, meaning you don't need to precede
|
|
|
27 |
it with the `new` operator. You can invoke it directly like this:
|
|
|
28 |
|
|
|
29 |
YUI().use('*', function (Y) {
|
|
|
30 |
// Y is a new YUI instance.
|
|
|
31 |
});
|
|
|
32 |
|
|
|
33 |
But it also works like this:
|
|
|
34 |
|
|
|
35 |
var Y = YUI();
|
|
|
36 |
|
|
|
37 |
The `YUI` constructor accepts an optional config object, like this:
|
|
|
38 |
|
|
|
39 |
YUI({
|
|
|
40 |
debug: true,
|
|
|
41 |
combine: false
|
|
|
42 |
}).use('node', function (Y) {
|
|
|
43 |
// Y.Node is ready to use.
|
|
|
44 |
});
|
|
|
45 |
|
|
|
46 |
See the API docs for the <a href="config.html">Config</a> class for the complete
|
|
|
47 |
list of supported configuration properties accepted by the YUI constuctor.
|
|
|
48 |
|
|
|
49 |
If a global `YUI` object is already defined, the existing YUI object will not be
|
|
|
50 |
overwritten, to ensure that defined namespaces are preserved.
|
|
|
51 |
|
|
|
52 |
Each YUI instance has full custom event support, but only if the event system is
|
|
|
53 |
available.

|

|
|
55 |

The easiest way to create a first-class YUI module is to use

<a href="http://yui.github.com/shifter/">Shifter</a>, the YUI component build

attached to this YUI instance. In this case, the `use()` callback will

860 |
be executed synchronously after the modules are attached.
|
|
|
861 |
|
|
|
862 |
* One or more modules have not yet been loaded, or the Get utility is not
|
|
|
863 |
available, or the `bootstrap` config option is `false`. In this case,
|
|
|
864 |
a warning is issued indicating that modules are missing, but all

available modules will still be attached and the `use()` callback will

* One or more modules are missing and the Loader is not available but the
|
|
|
869 |
Get utility is, and `bootstrap` is not `false`. In this case, the Get
|
|
|
870 |
utility will be used to load the Loader, and we will then proceed to
|
|
|
871 |
the following state:
|
|
|
872 |
|
|
|
873 |
* One or more modules are missing and the Loader is available. In this
|
|
|
874 |
case, the Loader will be used to resolve the dependency tree for the
|

875 |
missing modules and load them and their dependencies. When the Loader is
|
|
|
876 |
finished loading modules, the `use()` callback will be executed

asynchronously.

/**
|
|
|
1241 |
Utility method for safely creating namespaces if they don't already exist.
|
|
|
1242 |
May be called statically on the YUI global object or as a method on a YUI
|
|
|
1243 |
instance.
|
|
|
1244 |
|
|
|
1245 |
When called statically, a namespace will be created on the YUI global
|
|
|
1246 |
object:
|
|
|
1247 |
|
|
|
1248 |
// Create `YUI.your.namespace.here` as nested objects, preserving any
|
|
|
1249 |
// objects that already exist instead of overwriting them.
|
|
|
1250 |
YUI.namespace('your.namespace.here');
|
|
|
1251 |
|
|
|
1252 |
When called as a method on a YUI instance, a namespace will be created on
|
|
|
1253 |
that instance:
|
|
|
1254 |
|
|
|
1255 |
// Creates `Y.property.package`.
|
|
|
1256 |
Y.namespace('property.package');
|
|
|
1257 |
|
|
|
1258 |
Dots in the input string cause `namespace` to create nested objects for each
|
|
|
1259 |
token. If any part of the requested namespace already exists, the current
|
|
|
1260 |
object will be left in place and will not be overwritten. This allows
|
|
|
1261 |
multiple calls to `namespace` to preserve existing namespaced properties.
|
|
|
1262 |
|
|
|
1263 |
If the first token in the namespace string is "YAHOO", that token is
|
|
|
1264 |
discarded. This is legacy behavior for backwards compatibility with YUI 2.
|
|
|
1265 |
|
|
|
1266 |
Be careful with namespace tokens. Reserved words may work in some browsers
|
|
|
1267 |
and not others. For instance, the following will fail in some browsers
|
|
|
1268 |
because the supported version of JavaScript reserves the word "long":
|
|
|
1269 |
|
|
|
1270 |
Y.namespace('really.long.nested.namespace');
|
|
|
1271 |
|
|
|
1272 |
Note: If you pass multiple arguments to create multiple namespaces, only the
|
|
|
1273 |
last one created is returned from this function.
|
|
|
1274 |
|
|

This isn't guaranteed to be 100% accurate and won't work for anything other than

While his points are valid, it's still possible to benefit from this function

|
|
2170 |
negatives have minimal consequences. It's used internally to avoid using
|
|
|
2171 |
potentially broken non-native ES5 shims that have been added to the page by
|
|
|
2172 |
other libraries.

The native `Array.prototype.sort()` function converts values to strings and

sorts them in lexicographic order, which is unsuitable for sorting numeric

/**

3914 |
Performs a simple comparison between two version numbers, accounting for
|
|
|
3915 |
standard versioning logic such as the fact that "535.8" is a lower version than
|
|
|
3916 |
"535.24", even though a simple numerical comparison would indicate that it's
|
|
|
3917 |
greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are
|
|
|
3918 |
considered equivalent.
|
|
|
3919 |
|
|
|
3920 |
Returns -1 if version _a_ is lower than version _b_, 0 if they're equivalent,
|
|
|
3921 |
1 if _a_ is higher than _b_.
|
|
|
3922 |
|
|
|
3923 |
Versions may be numbers or strings containing numbers and dots. For example,
|
|
|
3924 |
both `535` and `"535.8.10"` are acceptable. A version string containing
|
|
|
3925 |
non-numeric characters, like `"535.8.beta"`, may produce unexpected results.

@property {Boolean} [options.async=false] Whether or not to load scripts
|
|
|
4083 |
asynchronously, meaning they're requested in parallel and execution
|
|
|
4084 |
order is not guaranteed. Has no effect on CSS, since CSS is always
|
|
|
4085 |
loaded asynchronously.
|
|
|
4086 |
|
|
|
4087 |
@property {Object} [options.attributes] HTML attribute name/value pairs that
|
|
|
4088 |
should be added to inserted nodes. By default, the `charset` attribute
|
|
|
4089 |
will be set to "utf-8" and nodes will be given an auto-generated `id`
|
|
|
4090 |
attribute, but you can override these with your own values if desired.
|
|

4091 |
|
|
|
4092 |
@property {Boolean} [options.autopurge] Whether or not to automatically
|
|
|
4093 |
purge inserted nodes after the purge threshold is reached. This is
|
|
|
4094 |
`true` by default for JavaScript, but `false` for CSS since purging a
|
|
|
4095 |
CSS node will also remove any styling applied by the referenced file.
|
|
|
4096 |
|
|
|
4097 |
@property {Object} [options.context] `this` object to use when calling
|
|
|
4098 |
callback functions. Defaults to the transaction object.
|
|
|
4099 |
|
|
|
4100 |
@property {Mixed} [options.data] Arbitrary data object to pass to "on*"
|
|
|
4101 |
callbacks.
|
|
|
4102 |
|
|
|
4103 |
@property {Document} [options.doc] Document into which nodes should be
|
|
|
4104 |
inserted. By default, the current document is used.
|
|
|
4105 |
|
|
|
4106 |
@property {HTMLElement|String} [options.insertBefore] HTML element or id
|
|
|
4107 |
string of an element before which all generated nodes should be
|
|
|
4108 |
inserted. If not specified, Get will automatically determine the best
|
|
|
4109 |
place to insert nodes for maximum compatibility.
|
|
|
4110 |
|
|
|
4111 |
@property {Function} [options.onEnd] Callback to execute after a transaction
|
|
|
4112 |
is complete, regardless of whether it succeeded or failed.
|
|
|
4113 |
|
|
|
4114 |
@property {Function} [options.onFailure] Callback to execute after a
|
|
|
4115 |
transaction fails, times out, or is aborted.
|
|
|
4116 |
|
|
|
4117 |
@property {Function} [options.onProgress] Callback to execute after each
|
|
|
4118 |
individual request in a transaction either succeeds or fails.
|
|
|
4119 |
|
|
|
4120 |
@property {Function} [options.onSuccess] Callback to execute after a
|
|
|
4121 |
transaction completes successfully with no errors. Note that in browsers
|
|
|
4122 |
that don't support the `error` event on CSS `<link>` nodes, a failed CSS
|
|
|
4123 |
request may still be reported as a success because in these browsers
|
|
|
4124 |
it can be difficult or impossible to distinguish between success and
|
|
|
4125 |
failure for CSS resources.
|
|
|
4126 |
|
|
|
4127 |
@property {Function} [options.onTimeout] Callback to execute after a
|
|
|
4128 |
transaction times out.
|
|
|
4129 |
|
|
|
4130 |
@property {Number} [options.pollInterval=50] Polling interval (in
|
|
|
4131 |
milliseconds) for detecting CSS load completion in browsers that don't
|
|
|
4132 |
support the `load` event on `<link>` nodes. This isn't used for
|
|
|
4133 |
JavaScript.
|
|
|
4134 |
|
|
|
4135 |
@property {Number} [options.purgethreshold=20] Number of nodes to insert
|
|
|
4136 |
before triggering an automatic purge when `autopurge` is `true`.
|
|
|
4137 |
|
|
|
4138 |
@property {Number} [options.timeout] Number of milliseconds to wait before
|
|
|
4139 |
aborting a transaction. When a timeout occurs, the `onTimeout` callback
|
|
|
4140 |
is called, followed by `onFailure` and finally `onEnd`. By default,
|
|
|
4141 |
there is no timeout.
|
|
|
4142 |
|
|
|
4143 |
@property {String} [options.type] Resource type ("css" or "js"). This option
|
|
|
4144 |
is set automatically by the `css()` and `js()` functions and will be
|
|
|
4145 |
ignored there, but may be useful when using the `load()` function. If
|
|
|
4146 |
not specified, the type will be inferred from the URL, defaulting to
|
|
|
4147 |
"js" if the URL doesn't contain a recognizable file extension.
