[jQuery] parent() modifies original object
I'm not sure if this is the way it's supposed to work, but this makes absolutely no sense to me as far as implementation goes. If I have code like this:
function someFunction( e )
{
var cell = $(e);
var cellParent =
cell.parent();
var cellParent2 = cell.parent();
alert("[" + cell.id() + "] [" + cellParent.id() + "] [" + cellParent2.id() + "]");
}
Instead of printing the equivalent of: $(e).id(), $(e).parent().id(), and $(e).parent().parent().id(), it prints $(e).parent.parent.id() three times. Further digging seems to hint at the fact that every time
cell.parent() is called, it's the equivalent of cell = cell.parent() and as such the original value of cell is lost.
Is this behavior intentional, or is it a bug? It seems quite counterintuitive to me, and while in the dumbed-down example above it makes more sense to use $(e).parent() instead of
cell.parent(), I find it more intuitive to use cell.parent() in other instances and thus discovered this behavior.
If it's unintentional, I'll start trying to find a fix and whip up some test cases too, I just wanted to check before I go fixing something that's not a bug in the first place.
Cheers,
