This seems quite bizarre.

Here's my experiment in the IE8 console:

typeof obj1 // object

obj1.hasOwnProperty // {...}



typeof obj2 // object

obj2.hasOwnProperty // undefined

Any ideas as to what could cause this?

This example is from IE8, but the same return is from IE6+ and most other IE browsers.

IE before #9 does not define it for host objects

var o=window;// or document or document elements

o.hasOwnProperty



/*  returned value: (undefined)

undefined

*/
