17 |
The YUI global namespace object. This is the constructor for all YUI instances.
|
|
|
18 |
|
|
|
19 |
This is a self-instantiable factory function, meaning you don't need to precede
|
|
|
20 |
it with the `new` operator. You can invoke it directly like this:
|
|
|
21 |
|
|
|
22 |
YUI().use('*', function (Y) {
|
|
|
23 |
// Y is a new YUI instance.
|
|
|
24 |
});
|
|
|
25 |
|
|
|
26 |
But it also works like this:
|
|
|
27 |
|
|
|
28 |
var Y = YUI();
|
|
|
29 |
|
|
|
30 |
The `YUI` constructor accepts an optional config object, like this:
|
|
|
31 |
|
|
|
32 |
YUI({
|
|
|
33 |
debug: true,
|
|
|
34 |
combine: false
|
|
|
35 |
}).use('node', function (Y) {
|
|
|
36 |
// Y.Node is ready to use.
|
|
|
37 |
});
|
|
|
38 |
|
|
|
39 |
See the API docs for the <a href="config.html">Config</a> class for the complete
|
|
|
40 |
list of supported configuration properties accepted by the YUI constuctor.
|
|
|
41 |
|
|
|
42 |
If a global `YUI` object is already defined, the existing YUI object will not be
|
|
|
43 |
overwritten, to ensure that defined namespaces are preserved.
|
|
|
44 |
|
|
|
45 |
Each YUI instance has full custom event support, but only if the event system is
|
|
|
46 |
available.

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

576 |
<a href="http://yui.github.com/shifter/">Shifter</a>, the YUI component build

|

Shifter will automatically wrap your module code in a `YUI.add()` call along

with any configuration info required for the module.

888 |
* One or more modules have not yet been loaded, or the Get utility is not

available, or the `bootstrap` config option is `false`. In this case,

the following state:

/**
|
|
|
1313 |
Utility method for safely creating namespaces if they don't already exist.
|
|
|
1314 |
May be called statically on the YUI global object or as a method on a YUI
|
|
|
1315 |
instance.
|
|
|
1316 |
|
|
|
1317 |
When called statically, a namespace will be created on the YUI global
|
|
|
1318 |
object:
|
|
|
1319 |
|
|
|
1320 |
// Create `YUI.your.namespace.here` as nested objects, preserving any
|
|
|
1321 |
// objects that already exist instead of overwriting them.
|
|
|
1322 |
YUI.namespace('your.namespace.here');
|
|
|
1323 |
|
|
|
1324 |
When called as a method on a YUI instance, a namespace will be created on
|
|
|
1325 |
that instance:
|
|
|
1326 |
|
|
|
1327 |
// Creates `Y.property.package`.
|
|
|
1328 |
Y.namespace('property.package');
|
|
|
1329 |
|
|
|
1330 |
Dots in the input string cause `namespace` to create nested objects for each
|
|
|
1331 |
token. If any part of the requested namespace already exists, the current
|
|
|
1332 |
object will be left in place and will not be overwritten. This allows
|
|
|
1333 |
multiple calls to `namespace` to preserve existing namespaced properties.
|
|
|
1334 |
|
|
|
1335 |
If the first token in the namespace string is "YAHOO", that token is
|
|

`false` otherwise. Will always return `false` -- even in ES5-capable browsers --

This isn't guaranteed to be 100% accurate and won't work for anything other than
|
|
|
2037 |
functions, but it can be useful for determining whether a function like
|
|
|
2038 |
`Array.prototype.forEach` is native or a JS shim provided by another library.

There's a great article by @kangax discussing certain flaws with this technique:

<http://perfectionkills.com/detecting-built-in-host-methods/>
|

2042 |
|

While his points are valid, it's still possible to benefit from this function
|
|
|
2044 |
as long as it's used carefully and sparingly, and in such a way that false
|
|
|
2045 |
negatives have minimal consequences. It's used internally to avoid using
|
|
|
2046 |
potentially broken non-native ES5 shims that have been added to the page by
|
|
|
2047 |
other libraries.

Performs a simple comparison between two version numbers, accounting for
|
|
|
3837 |
standard versioning logic such as the fact that "535.8" is a lower version than
|
|
|
3838 |
"535.24", even though a simple numerical comparison would indicate that it's
|
|
|
3839 |
greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are
|
|
|
3840 |
considered equivalent.
|
|
|
3841 |
|
|
|
3842 |
Returns -1 if version _a_ is lower than version _b_, 0 if they're equivalent,
|
|

3843 |
1 if _a_ is higher than _b_.
|

|
3844 |

Versions may be numbers or strings containing numbers and dots. For example,
|
|
|
3846 |
both `535` and `"535.8.10"` are acceptable. A version string containing
|
|
|
3847 |
non-numeric characters, like `"535.8.beta"`, may produce unexpected results.

@property {Object} options
|
|
|
4003 |
|
|
|
4004 |
@property {Boolean} [options.async=false] Whether or not to load scripts
|
|
|
4005 |
asynchronously, meaning they're requested in parallel and execution
|
|
|
4006 |
order is not guaranteed. Has no effect on CSS, since CSS is always
|
|
|
4007 |
loaded asynchronously.
|
|
|
4008 |
|
|
|
4009 |
@property {Object} [options.attributes] HTML attribute name/value pairs that
|
|
|
4010 |
should be added to inserted nodes. By default, the `charset` attribute
|
|
|
4011 |
will be set to "utf-8" and nodes will be given an auto-generated `id`
|
|
|
4012 |
attribute, but you can override these with your own values if desired.
|
|
|
4013 |
|
|
|
4014 |
@property {Boolean} [options.autopurge] Whether or not to automatically
|
|
|
4015 |
purge inserted nodes after the purge threshold is reached. This is
|
|
|
4016 |
`true` by default for JavaScript, but `false` for CSS since purging a
|
|
|
4017 |
CSS node will also remove any styling applied by the referenced file.
|
|
|
4018 |
|
|
|
4019 |
@property {Object} [options.context] `this` object to use when calling
|
|
|
4020 |
callback functions. Defaults to the transaction object.
|
|
|
4021 |
|
|
|
4022 |
@property {Mixed} [options.data] Arbitrary data object to pass to "on*"
|
|
|
4023 |
callbacks.
|
|
|
4024 |
|
|
|
4025 |
@property {Document} [options.doc] Document into which nodes should be
|
|
|
4026 |
inserted. By default, the current document is used.
|
|
|
4027 |
|
|
|
4028 |
@property {HTMLElement|String} [options.insertBefore] HTML element or id
|
|
|
4029 |
string of an element before which all generated nodes should be
|
|
|
4030 |
inserted. If not specified, Get will automatically determine the best
|
|
|
4031 |
place to insert nodes for maximum compatibility.
|
|
|
4032 |
|
|
|
4033 |
@property {Function} [options.onEnd] Callback to execute after a transaction
|
|
|
4034 |
is complete, regardless of whether it succeeded or failed.
|
|
|
4035 |
|
|
|
4036 |
@property {Function} [options.onFailure] Callback to execute after a
|
|
|
4037 |
transaction fails, times out, or is aborted.
|
|
|
4038 |
|
|
|
4039 |
@property {Function} [options.onProgress] Callback to execute after each
|
|
|
4040 |
individual request in a transaction either succeeds or fails.
|
|
|
4041 |
|
|
|
4042 |
@property {Function} [options.onSuccess] Callback to execute after a
|
|
|
4043 |
transaction completes successfully with no errors. Note that in browsers
|
|
|
4044 |
that don't support the `error` event on CSS `<link>` nodes, a failed CSS
|
|
|
4045 |
request may still be reported as a success because in these browsers
|
|
|
4046 |
it can be difficult or impossible to distinguish between success and
|
|
|
4047 |
failure for CSS resources.
|
|
|
4048 |
|
|
|
4049 |
@property {Function} [options.onTimeout] Callback to execute after a
|
|
|
4050 |
transaction times out.
|
|
|
4051 |
|
|
|
4052 |
@property {Number} [options.pollInterval=50] Polling interval (in
|
|
|
4053 |
milliseconds) for detecting CSS load completion in browsers that don't
|
|
|
4054 |
support the `load` event on `<link>` nodes. This isn't used for
|
|
|
4055 |
JavaScript.
|
|
|
4056 |
|
|
|
4057 |
@property {Number} [options.purgethreshold=20] Number of nodes to insert
|
|
|
4058 |
before triggering an automatic purge when `autopurge` is `true`.
|
|
|
4059 |
|
|
|
4060 |
@property {Number} [options.timeout] Number of milliseconds to wait before
|
|
|
4061 |
aborting a transaction. When a timeout occurs, the `onTimeout` callback
|
|
|
4062 |
is called, followed by `onFailure` and finally `onEnd`. By default,
|
|
|
4063 |
there is no timeout.
|
|
|
4064 |
|
|
|
4065 |
@property {String} [options.type] Resource type ("css" or "js"). This option
|
|
|
4066 |
is set automatically by the `css()` and `js()` functions and will be
|
|
|
4067 |
ignored there, but may be useful when using the `load()` function. If
|
|
|
4068 |
not specified, the type will be inferred from the URL, defaulting to
|
|
|
4069 |
"js" if the URL doesn't contain a recognizable file extension.

The _urls_ parameter may be provided as a URL string, a request object,

4220 |
or an array of URL strings and/or request objects.
|

A request object is just an object that contains a `url` property and zero
