Answer 1

您应该通过以下方式使用prop函数：

$(this).prop('checked', false);

Answer 2

尝试这个：

newDiv.find('input').each(function () { $(this).prop('checked', false).val(''); });

Answer 3

I think it's a mistake to set the value after removing the attr.

I've had better luck doing this:

$(this).attr('checked', false);

A checkbox's checked state is inseparable from the element; you can no more remove its is-checked/is-not-checked state than you can remove it's HTML-element-ness. Instead, indicate that the checkbox should be unchecked.
