[Solved] c.defaultView.getComputedStyle(h, null) is null – Error


Why jquery doesnt work properly on iframes with firefox


The final solution was to update jQuery to lastest version.

This is a bug that was fixed in version 1.6.1 (http://blog.jquery.com/2011/05/12/jquery-1-6-1-released/, item #8763)

onmouseover cursor using firefox: SOLVED!!

QUoting from David Harrison @webdeveloper.com:

It’s not hand, it’s pointer. M$ decided to throw caution to the wind and employ some MORE non-standard code. You don’t need to say onmouseover though since the rule will only apply to when the mouse is over the element anyway, so just do this:<some-tag style=”cursor:pointer;cursor:hand;”></some-tag>You have to specify pointer first, then hand. IE5 trips up because it doesn’t understand pointer (IE6 understands pointer though).
FYI, you didn’t reference the element properly either, should have been “this.style.cursor=’whatever’;”.
