几种方法可以做到这一点.一种方法是使用 ng-if ="todayBirthday?onlyToday(friend):true" : http://plnkr.co/edit/kMGIlNcESjg4kYE3oHhY?p=preview

A few ways to do this. One way is to use ng-if="todayBirthday ? onlyToday(friend) : true": http://plnkr.co/edit/kMGIlNcESjg4kYE3oHhY?p=preview

$scope.onlyToday = function(friend) {
  var today = new Date();

  if(friend.birthDate.getDate() === today.getDate() && friend.birthDate.getMonth() === today.getMonth())
    return true;
  else
    return false;
}
