object has no hasOwnProperty method (i.e. it's undefined) - IE8
hasownproperty, ie-developer-tools, internet-explorer-8, javascript
Solution
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
*/
Problem
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?
