javascript - jQuery 3.0 removeAttr 与 prop

Question

我刚刚读到了 jQuery 3.0 的重大变化，我想所有前端工程师都应该知道这一点。

例如问题，1. 如何取消选中复选框？2. 如何去掉单选按钮的勾选？

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

Answer 1

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.
