input标签设置时间值
研究了两天javascript⽇期相关的内容,⼀句话总结:“浏览器可以⽤上⼗万年,因为javascript⽀持的时间范围就是这么长”。通过实验来看,⽐较好⽤的是type="date",及type="datetime-local"
关于设置值的结论:
(1)2020-03-26格式可⽤于date、datetime
(2)2020-03-26 22:32:07格式仅可以⽤于datetime
(3)2020-03-26T22:33:03格式可以⽤于datetime、datetime-local
关于输⼊及校验⽇期的正确性:能输⼊不代表就能正确转换成⽇期
代码:没写过WEB程序,算是个练习,将就着看吧。

<!--jquery中attr和prop的区别介绍:
•对于HTML元素本⾝就带有的固有属性,在处理时,使⽤prop⽅法。
•对于HTML元素我们⾃⼰⾃定义的DOM属性,在处理时,使⽤attr⽅法。-->
