39 |
* The base dir</li> |

|

46 |
* <li>filter: |
|
|
47 |
* |
|
|
48 |
* A filter to apply to result urls. This filter will modify the default |
|
|
49 |
* path for all modules. The default path for the YUI library is the |
|
|
50 |
* minified version of the files (e.g., event-min.js). The filter property |

|
|
53 |
* <dl> |
|
|
54 |
* <dt>DEBUG</dt> |
|
|
55 |
* <dd>Selects the debug versions of the library (e.g., event-debug.js). |
|
|
56 |
* This option will automatically include the Logger widget</dd> |
|
|
57 |
* <dt>RAW</dt> |
|
|
58 |
* <dd>Selects the non-minified version of the library (e.g., event.js).</dd> |
|
|
59 |
* </dl> |
|
|
60 |
* You can also define a custom filter, which must be an object literal |
|
|
61 |
* containing a search expression and a replace string: |
|

62 |
* <pre> |
|
|
63 |

* </pre> |
|
|
68 |
* |
|
|
69 |

|
|
70 |
* <li>filters: per-component filter specification. If specified for a given component, this overrides the filter config</li> |
|
|
71 |
* <li>combine: |
|
|
72 |
* Use the YUI combo service to reduce the number of http connections required to load your dependencies</li> |

|
|
81 |
* <li>jsAttributes: object literal containing attributes to add to script nodes</li> |
|
|
82 |
* <li>cssAttributes: object literal containing attributes to add to link nodes</li> |
|
|
83 |
* <li>timeout: |
|
|
84 |
* number of milliseconds before a timeout occurs when dynamically loading nodes. in not set, there is no timeout</li> |
|
|
85 |
* <li>context: |
|
|
86 |
* execution context for all callbacks</li> |
|
|
87 |
* <li>onSuccess: |
|

|
|
89 |
* <li>onFailure: callback for the 'failure' event</li> |
|
|
90 |

91 |
