Answer 1

Because in IE7 elem.attributes lists all possible attributes, not only the present ones, we have to test the attribute value. This plugin works in all major browsers:

(function($) {
    $.fn.getAttributes = function () {
        var elem = this, 
            attr = {};

        if(elem && elem.length) $.each(elem.get(0).attributes, function(v,n) { 
            n = n.nodeName||n.name;
            v = elem.attr(n); // relay on $.fn.attr, it makes some filtering and checks
            if(v != undefined && v !== false) attr[n] = v
        })

        return attr
    }
})(jQuery);

Usage:

var attribs = $('#some_id').getAttributes();
