YUI.namespace('your.namespace.here'); When called as a method on a YUI instance, a namespace will be created on that instance: // Creates `Y.property.package`. Y.namespace('property.package'); Dots in the input string cause `namespace` to create nested objects for each token. If any part of the requested namespace already exists, the current object will be left in place and will not be overwritten. This allows multiple calls to `namespace` to preserve existing namespaced properties. If the first token in the namespace string is "YAHOO", that token is discarded. This is legacy behavior for backwards compatibility with YUI 2. Be careful with namespace tokens. Reserved words may work in some browsers and not others. For instance, the following will fail in some browsers because the supported version of JavaScript reserves the word "long": Y.namespace('really.long.nested.namespace'); Note: If you pass multiple arguments to create multiple namespaces, only the last one created is returned from this function. @method namespace @param {String} namespace* One or more namespaces to create. @return {Object} Reference to the last namespace object created. **/ namespace: function() { var a = arguments, o, i = 0, j, d, arg; for (; i < a.length; i++) { o = this; //Reset base object per argument or it will get reused from the last arg = a[i]; if (arg.indexOf(PERIOD) > -1) { //Skip this if no "." is present d = arg.split(PERIOD); for (j = (d[0] == 'YAHOO') ? 1 : 0; j < d.length; j++) { o[d[j]] = o[d[j]] || {}; o = o[d[j]]; } } else { o[arg] = o[arg] || {}; o = o[arg]; //Reset base object to the new object so it's returned } } return o; }, // this is replaced if the log module is included log: NOOP, message: NOOP, // this is replaced if the dump module is included dump: function (o) { return ''+o; }, /** Reports an error.
