And there it is, as hinted by friend Firebug :)
// "true"
window.alert($("#a1")[0] == $("#a1")[0]);
When passed a string expression, jQuery's $() method returns a kind of
augmented collection[1] of element objects for matching elements. Quite
obviously, when one attempts to match by ID which must be unique
throughout
a Valid do***ent, the first and only item of that collection is the
reference to the target element object.
It should be noted, though, that we are dealing with host objects here,
and
therefore the equals operation does not need to work like with native
objects. (Nevertheless, no hard proof has been provided yet of an
implementation showing different behavior.)
