If the attribute was declared with the [Unforgeable] extended attribute, then the property exists on every object that implements the interface. Otherwise, it exists on the interface’s interface prototype object." WebKit, however, appears to define these as instance properties. This introduces several incompatibilities, such as checking own properties or getting property descriptors. For a specific example, In WebKit and Presto: > document.body.hasOwnProperty("style") // -> true In Trident and Gecko: > document.body.hasOwnProperty("style") // -> false 491083 1 ap 2011-10-26 12:10:43 -0700 *** This bug has been marked as a duplicate of bug 68002 ***
