Update: I see you just changed the question. Now the solution would be this:
更新：我看到你刚刚改变了问题。现在的解决方案是这样的：
var s = '<h1>heading</h1><p>para</p>';
var $s = $(s).not('h1');
$('body').append($s);?

Because you now have more than one "top level" element in the jQuery object, you can use .not()(which is basically the opposite of .filter()) to remove the h1.
因为您现在在 jQuery 对象中有多个“顶级”元素，您可以使用.not()（基本上与 相反.filter()）删除h1.
It would be the same as doing $(s).filter(':not(h1)');
这和做一样 $(s).filter(':not(h1)');
Original answer
原答案
$(s).find('h1').remove();
So if you were to append the result to the body, you could do:
因此，如果要将结果附加到body，则可以执行以下操作：
var s = '<div><h1>heading</h1><p>para</p></div>';
var $s = $(s).find('h1').remove().end();
$('body').append($s);?
