localStorage.key() does not return null for indicies >= localStorage.length

• Component: DOM
• Status: RESOLVED FIXED

[Brett C.]

The W3C Web Storage spec says that for localStorage.key() (http://dev.w3.org/html5/webstorage/#dom-storage-key) null should be returned when the value passed in is equal to or greater than what localStorage.length returns (and the same obviously goes for sessionStorage). But if you do ``localStorage.key(localStorage.length)`` in Safari 4.0.2, instead of getting null you get ``Error: INDEX_SIZE_ERR: DOM Exception 1``.
