<div>No attributes yet</div>

Answer 1

您可以使用 native Node#attributes属性: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"));
