Ant Design of Vue a-form表单效验用法(二)
(这里添加上期的间隔效验用法：v-if导致的表单不能效验问题，moment时间的用法，表单回调)
效果图：
1、（选中周期时在选中生效时段，失去焦点后效验：）
2、
1、（首日、最后一日、几号 同）
2、
（这里考虑到如果先选择生效时段在选周期的话，采用提交表单时效验）

v-if导致的表单不能效验问题
（很多时候在操作v-if、v-show的时候会使得表单中的自动效验未能生效）
使用v-if：v-if用来切换的元素是会被销毁的，导致了
v-if内的表单项，由于在mounted时期没有进行渲染，所以规则也没有绑定上。
初始化时不符合显示条件的不会生成规则，导致后面切换条件，显示的输入框的校验不会生效- 使用
v-show：初始化时会生成所有的规则，即使隐藏了也会进行规则校验
方法：全部改为v-show
