如何避免角度js中的十进制数？

<div class="col-md-6 col-sm-6"> 
  <label class="col-md-5 col-sm-5 pad-top5 pad-lft-no">Mins <span class="error">*</span></label>
  <input positive  type="number" class="col-md-7 col-sm-7 cls_input_inherit numberinput" min="0" ng-maxlength="3" id="age_min" name="age_min" ng-model="attributes.age_min" step="1" required/>
  <label for="age_min" ng-show="submittab2 && attributesForm2.age_min.$error.required" class="error">{{formValidation.required}}</label>                                                           
  <label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive &&  attributesForm2.age_min.$error.maxlength" class="error"> {{formValidation.monthMaxChar}} </label>
  <label for="age_min" ng-show="submittab2 && !attributesForm2.age_min.$error.positive && !attributesForm2.age_min.$error.maxlength && attributesForm2.age_min.$error.min" class="error">{{formValidation.minMax}}</label>

当用户输入小数值时，它没有显示任何错误？我试过步骤=＆＃34; 1＆＃34;和ng-pattern一样，两个都不工作，我的代码是否有任何错误显示十进制值的错误消息？如何在用户输入十进制值时显示该错误消息？

Answer 1

您可以使用ng-pattern。

class Image(BaseImage):
    article = models.ForeignKey(Article, verbose_name=u'Новость', null=True)
    in_preview = models.BooleanField(u'Отображать в превью', default=False)
    weight = models.IntegerField(u'Порядок', default=0)

    class Meta:
        verbose_name = u'Изображение'
        verbose_name_plural = u'Изображения'
        ordering = ('weight',)

    def get_upload_to(self, filename):
        return os.path.join('articles', 'image', 'image_file', filename)

    def list_thumbnail_tag(self):
        source = self.image_file
        if source:
            thumbnail = get_thumbnailer(source).get_thumbnail({'size': (100, 100), 'crop': True})
            return '<img src="{}">'.format(thumbnail.url)

    list_thumbnail_tag.short_description = 'Превью'
    list_thumbnail_tag.allow_tags = True

class BaseImage(models.Model):
    image_file = models.ImageField(u'Файл', upload_to='uploads')
    image_alt = models.CharField(u'Атрибут Alt', max_length=255, blank=True)
    image_title = models.CharField(u'Название', max_length=255, blank=True)

    def __str__(self):
        return os.path.basename(self.image_file.path)

    def get_upload_to(self, filename):
        return os.path.join('images', filename)

    class Meta:
        abstract = True
        verbose_name = u'Изображение'
        verbose_name_plural = u'Изображения'

这是有效的Plunker
