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.

|
|
|
597 |
|

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

|
|
599 |
<a href="http://yui.github.com/shifter/">Shifter</a>, the YUI component build
|
|
|

tool.

|
601 |
|
|
|
602 |
Shifter will automatically wrap your module code in a `YUI.add()` call along
|
|
|
603 |
with any configuration info required for the module.

informational purposes, and is not used internally by YUI.

|
|

925 |
* One or more modules have not yet been loaded, or the Get utility is not

the following state:

/**
|
|
|
1350 |
Utility method for safely creating namespaces if they don't already exist.
|
|
|
1351 |
May be called statically on the YUI global object or as a method on a YUI
|
|
|
1352 |
instance.
|
|
|
1353 |
|
|
|
1354 |
When called statically, a namespace will be created on the YUI global
|
|
|
1355 |
object:
|
|
|
1356 |
|
|
|
1357 |
// Create `YUI.your.namespace.here` as nested objects, preserving any
|
|
|
1358 |
// objects that already exist instead of overwriting them.
|
|
|
1359 |
YUI.namespace('your.namespace.here');
|
|
|
1360 |
|
|
|
1361 |
When called as a method on a YUI instance, a namespace will be created on
|
|
|
1362 |
that instance:
|
|
|
1363 |
|
|
|
1364 |
// Creates `Y.property.package`.
|
|
|
1365 |
Y.namespace('property.package');
|
|
|
1366 |
|
|
|
1367 |
Dots in the input string cause `namespace` to create nested objects for each
|
|
|
1368 |
token. If any part of the requested namespace already exists, the current
|
|
|
1369 |
object will be left in place and will not be overwritten. This allows
|
|
|
1370 |
multiple calls to `namespace` to preserve existing namespaced properties.
|
|
|
1371 |
|
|
|
1372 |
If the first token in the namespace string is "YAHOO", that token is
|
|
|
1373 |
discarded. This is legacy behavior for backwards compatibility with YUI 2.
|
|
|
1374 |
|
|
|
1375 |
Be careful with namespace tokens. Reserved words may work in some browsers
|
|
|
1376 |
and not others. For instance, the following will fail in some browsers
|
|
|
1377 |
because the supported version of JavaScript reserves the word "long":
|
|
|
1378 |
|
|
|
1379 |
Y.namespace('really.long.nested.namespace');
|
|
|
1380 |
|
|
|
1381 |
Note: If you pass multiple arguments to create multiple namespaces, only the
|
|
|
1382 |
last one created is returned from this function.
|
|
|
1383 |
|
|
|
1384 |
@method namespace
|
|
|
1385 |
@param {String} namespace* One or more namespaces to create.

This isn't guaranteed to be 100% accurate and won't work for anything other than
|
|
|
2064 |
functions, but it can be useful for determining whether a function like
|
|

`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:

While his points are valid, it's still possible to benefit from this function
|
|
|
2071 |
as long as it's used carefully and sparingly, and in such a way that false
|
|
|
2072 |
negatives have minimal consequences. It's used internally to avoid using
|
|
|
2073 |
potentially broken non-native ES5 shims that have been added to the page by
|
|
|
2074 |
other libraries.

/**
|
|
|
3922 |
Performs a simple comparison between two version numbers, accounting for
|
|
|
3923 |
standard versioning logic such as the fact that "535.8" is a lower version than
|
|
|
3924 |
"535.24", even though a simple numerical comparison would indicate that it's
|
|
|
3925 |
greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are
|
|
|
3926 |
considered equivalent.
|
|
|
3927 |
|
|
|
3928 |
Returns -1 if version _a_ is lower than version _b_, 0 if they're equivalent,
|
|
|
3929 |
1 if _a_ is higher than _b_.
|
|
|
3930 |
|
|
|
3931 |
Versions may be numbers or strings containing numbers and dots. For example,
|
|
|
3932 |
both `535` and `"535.8.10"` are acceptable. A version string containing
|
|
|
3933 |
non-numeric characters, like `"535.8.beta"`, may produce unexpected results.

|
|
|
3936 |
@param {Number|String} a First version number to compare.

3937 |
@param {Number|String} b Second version number to compare.
|

3938 |

higher than _b_.
