JSLint doesn't like DOM types:



Element

NodeList

etc.



So you can't do (foo instanceof Element) to see if it's a HTMLElement, or (foo

instanceof NodeList) to see if it's a NodeList.



Currently I make it work by putting a /*global */ statement at the top of my

programs:



/*global Element, NodeList */



Using "var Element, NodeList;" causes errors, so I -must- use the /*global */

construct.



Any chance of JSLint becoming aware of the DOM types?

I will add them when IE adds them. Currently, I think it is more helpful for

JSLint to report that NodeList is not available on 80% of browsers.

Understandable. Er, IE still holds 80% of the market share? If I recall,

basically every browser other than IE supports NodeList, and that IE has closer

to 68% market share (along with all the disclaimers about how unreliable market

share tests are).

By the way, I ran some tests in IE8. Apparently IE8 *does* support Element, but

not NodeList:





var body = document.getElementsByTagName("body");

console.log("Element: " + (body[0] instanceof Element)); // true

console.log("NodeList: " + (body instanceof NodeList));  // false





I have no clue whether IE7 or IE6 support Element, however.
