    you could create a temp element and att attributes to it and then append all of its attributes to the body:

    var x = 'class="test test1 test2" id="xyz" style="color:red"',
    temp = $("<b "+x+">")[0],
    attr = {};
for (var i=0, attrs=temp.attributes, l=attrs.length; i<l; i++){
    attr[attrs.item(i).nodeName] = attrs.item(i).value;
}

$("body").attr(attr);

    but if you can then make the class, id and style as an object instead of a string, will save some code for you.
