单击“提交”按钮后,表单将被提交,而不是验证必填字段。

如果表单是有效的,则调用函数的最短方式如下所示,仅当表单有效时才会激活有效function

ng-submit="myForm.$valid && valid()"

或者其他方式是检查myForm中的$scope对象,因为当您在表单上提供name="myForm"时,angular会在范围内创建一个对象,其中包含所有信息字段信息对象

$scope.valid = function(){
   if($scope.myForm.$valid){
      //form is valid
      //do $http.post call if you wanted to submit form data
   }
   else {
      alert('form is invalid');//some how notify user that form is invalid.
   }
}

尝试放置:

$scope.valid=function() {
  if ($scope.myForm.isValid()) $scope.msg="form submitted";
  else $scope.msg="form with errors";
}

希望有所帮助

您可以使用以下命令禁用提交按钮:

ng-disabled="boolean expression"

在你的情况下,它将是简单的:

<input type="submit" value="submit" ng-disabled="!myForm.$valid">
