Internet Explorer weirdness - function item() { [native code] } - what does it do?
internet-explorer, internet-explorer-9, javascript
Solution
It's a function on the `window` object. in Internet Explorer. It's not part of the websites, in other words, it's part of the browser.
It's from the HTMLCollection interface, part of the DOM spec. Internet Explorer seems to consider the `window` object to be a collection.
Problem
See image: Similar question on Microsoft website: http://connect.microsoft.com/IE/feedback/details/785194/function-item-native-code Tried Google.com, Facebook, StackOverflow - every website I visit has this weird feature. Fire up your IE9 (haven't tested other versions) and type `item` in you development console. If I haven't tried other websites I would think that there is a `<div id="item">` see also: - Do DOM tree elements with ids become global variables? - How to force Chrome (or any other WebKit browser) not to use "default" tag names? (this is my question asking how to stop it) So on this occasion the question is - why `function item()` is present on so many websites when IE is used? UPDATE: super simplified test case.
