<title>Invalid key</title>
<link rel=help href="http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#key-construct">
<link rel=assert title="A value is said to be a valid key if it is one of the following types: Array JavaScript objects [ECMA-262], DOMString [WEBIDL], Date [ECMA-262] or float [WEBIDL]. However Arrays are only valid keys if every item in the array is defined and is a valid key (i.e. sparse arrays can not be valid keys) and if the Array doesn't directly or indirectly contain itself. Any non-numeric properties are ignored, and thus does not affect whether the Array is a valid key. Additionally, if the value is of type float, it is only a valid key if it is not NaN, and if the value is of type Date it is only a valid key if its [[PrimitiveValue]] internal property, as defined by [ECMA-262], is not NaN. Conforming user agents must support all valid keys as keys.">
