用JavaScript比较两个日期

Question

有人可以建议一种方法来比较使用JavaScript大于，小于和过去的两个日期的值吗？值将来自文本框。

Answer 1

比较<和>正常情况一样，但任何涉及的=都应该使用+前缀。像这样：var x = new Date('2013-05-23');var y = new Date('2013-05-23');// less than, greater than is fine:x < y; => falsex > y; => falsex === y; => false, oops!// anything involving '=' should use the '+' prefix// it will then compare the dates' millisecond values+x <= +y;&nbsp; => true+x >= +y;&nbsp; => true+x === +y; => true希望这可以帮助！
