日期不适用于IE9的Angular ng-pattern

Question

我试图在视图中使用ng-pattern来使用低于日期(mm/dd/yyyy)的验证模式.

 ng-pattern="/^(\d{4})-(\d{2})-(\d{2})$/"

一旦我开始输入日期,验证错误就会出现,并且在有效日期(例如10/15/1988)之后仍然存在

我尝试使用var传递它通过控制器(如下所示)但行为相同:

在控制器中:

  $scope.myPattern = "/^(\d{4})-(\d{2})-(\d{2})$/";

在视图中:

  ng-pattern="{{myPattern}}"

注意:这两种方法都不适用于IE9

Answer 1

怎么样:

 /^((\d{4})-(\d{2})-(\d{2})|(\d{2})\/(\d{2})\/(\d{4}))$/

这适用于dd/mm/yyyy和yyyy-mm-dd

/^((\d{4})-(\d{2})-(\d{2})|(\d{2})\/(\d{2})\/(\d{4}))$/.test('04/04/1974')
true
/^((\d{4})-(\d{2})-(\d{2})|(\d{2})\/(\d{2})\/(\d{4}))$/.test('1974-04-04')
true
