剑道网格日期格式验证不起作用

Question

为什么当我输入无效格式时只显示字段名称。即使我尝试了不同的验证样式，它仍然会显示格式是否无效。我已经创建了自定义验证，但它仅在日期为空或 null 时才有效，但如果不是，则它不起作用，这是因为当我在字段中输入错误格式时，自定义验证不起作用。

Answer 1

尝试更改您要添加的属性名称。

更改以下内容：

input.attr("data-custom-msg", "Start date is required.");

收件人：

input.attr("data-lot_start_date-msg", "Start date is required.");

Answer 2

所以我所做的就是将自定义验证更改为日期验证，并在验证内创建一个条件以确定它是否为空以及是否有不正确的格式。
