安全校验：
 $scope.confirmReason = function (reason, reasonForm) {

        if(!!$scope.reason.value && $scope.reason.value.length > 50){
          reasonForm.returnReason.$setValidity("reasonMaxLength", false);
          return false; //if条件为true时，显示<small>
        }else{
          reasonForm.returnReason.$setValidity("reasonMaxLength", true);
        }

        if (reasonForm.$invalid) {
          reasonForm.doValidate();
          return false;
        }
//reasonForm: form表单name值，作为函数参数传入
<small ng-show="reasonForm.returnReason.$error.reasonMaxLength" style="color: #843534;">该选项输入值长度不能大于50</small>
//关闭窗口
$scope.cancel = function () {
  $modalInstance.dismiss('cancel');
}

modalInstance.result.then(function (reason) {
  //保存正确跳到下一题
  // $scope.getQuestion(false);
});

ng form 会给根据具体情况给表单里的每项自动添加下列 css class：
ng-valid: 验证通过
ng-invalid: 验证没有通过
ng-pristine: 用户没有输入任何东西
ng-dirty: 用户输入了东西， 不管最终值有木有改变。 例如开始里面是空的， 填写了ab， 之后又吧ab删除了， 这是也是dirty的.
