Bug 135008 – document.body.hasOwnProperty('childNodes') returns false

• Status: RESOLVED
• Resolution: INVALID
• Component: DOM

[ShihChi Huang]

I cannot use webkit nightly in Yosemite so not sure if it's still a problem in latest build.

However, both Safari 8.0 and iOS Safari 8.0 returns false while executing below expression

```js
document.body.hasOwnProperty('childNodes')
```

[Sam Weinig]

This is expected, since the childNodes property is now on the prototype.  Is this breaking something for you?

[ShihChi Huang]

May I know what's the expected behavior? 

in safari prior to ios8 / yosemite and latest stable chrome browser it still returns true while executing document.body.hasOwnProperty('childNodes')

[Junwei Liang]

Any update on this?
We have exactly the same problem when call 'hasOwnProperty' on DOM elements.
In safari prior to ios8/yosemite, it always returns true!

````js
var el = document.getElementById('dummy-div-id');
console.log(el.hasOwnProperty('className')); // false
````

This is the expected behavior as per comment 1 and all browsers these days agree.
