Timo Tijhof c8ed44fb07 Refactor ve.getHash: Stabilize cross-browser differences; + unit tests ... * Replaces c8b4a28936 * Use Object() casting to detect objects instead of .constructor (or instanceof). Both .constructor and instanceof compare by reference the type "Object" which means if the object comes from another window (where there is a different "Object" and "Object.prototype") it will drop out of the system and go freewack. Theory: If a variable casted to an object returns true when strictly compared to the original, the input must be an object. Which is true. It doesn't change the inheritance, it doesn't make it inherit from this window's Object if the object is from another window's object. All it does is cast to an object if not an object already. So e.g. "Object(5) !== 5" because 5 is a primitive value as opposed to an instance of Number. And contrary to "typeof", it doesn't return true for "null". * .constructor also has the problem that it only works this way if the input is a plain object. e.g. a simple construtor function that creates an object also get in the wrong side of the if/else case since it is an instance of Object, but not directly (rather indirectly via another constructor). * Added unit tests for basic getHash usage, as well as regression tests against the above two mentioned problems (these tests fail before this commit). * While at it, also improved other utilities a bit. - Use hasOwnProperty instead of casting to boolean when checking for presence of native support. Thanks to Douglas Crockford for that tip. - Fix documentation for ve.getHash: Parameter is not named "obj". - Add Object-check to ve.getObjectKeys per ES5 Object.keys spec (to match native behavior) - Add Object-check to ve.getObjectValues to match ve.getObjectKeys - Improved performance of ve.getObjectKeys shim. Tried several potential optimizations and compared with jsperf. Using a "static" reference to hasOwn improves performance (by not having to look it up 4 scopes up and 3 property levels deep). Also using [.length] instead of .push() shared off a few ms. - Added unit tests for ve.getObjectValues Change-Id: If24d09405321f201c67f7df75d332bb1171c8a36		2012-08-27 00:14:02 +02:00
