each() cannot work well with a literal object who has a length member

[ZengWq572]

if i have a literal object:

var objWithLength =[[BR]]
    length: 2,[[BR]]
    a: 1[[BR]]
};
jQuery.each(objWithLength, function(key, value){[[BR]]
    alert(key + ', ' + value);[[BR]]
});[[BR]]

the each() function cannot work as what i want.

i read the source of jQuery, the each(obj, ...) function only checks 'obj.length' attribute and isFunction(obj). Do you do this for purpose?

if i have the honor, i hope you can sent me an reply.

thank you!

if i have a literal object with length attribute, the each() function cannot work well as what i want. For example:

var objWithLength = {
    length: 2,
    a: 1
};
jQuery.each(objWithLength, function(key, value){
    alert(key + ': ' + value);
});

the each() function will alert out ''1: undefined'' and ''2: undefined''.

This may get marked wontfix, but there is still a little bit of wiggle room here.
