You can use the native Node#attributes
property: http://jsfiddle.net/SDWHN/16/.
var $select = $("select");
var $div = $("div");
var attributes = $select.prop("attributes");
// loop through <select> attributes and apply them on <div>
$.each(attributes, function() {
$div.attr(this.name, this.value);
});
alert($div.data("foo"));
