Notification.success({ message: '<i class="glyphicon glyphicon-ok"></i> Article saved successfully!' });
}
function errorCallback(res) {
Notification.error({ message: res.data.message, title: '<i class="glyphicon glyphicon-remove"></i> Article save error!' });
}
}
}
}());
状况:
当我点击提交时出现空textarea
时,错误消息“min:1400 characters max:14000 characters”不会出现。
目前使用mean.js并自定义它以学习MEAN堆栈。
如何重现:
下载mean.js:https://github.com/meanjs/mean
文件如下:modules / articles / client / views / admin / form-article.client.view.html
答案 0 :(得分:1)
您需要为maxlength validation添加消息类型。
目前只有当您因为必需的标志而没有任何文本时才会显示一条消息,但是一旦达到最大长度,您将看不到该消息。
<div ng-messages="vm.form.articleForm.content.$error" role="alert">
<p class="help-block error-text" ng-message="required">min: 1400 characters max: 14000</p>
</div>
为邮件添加以下内容。
<div ng-messages="vm.form.articleForm.content.$error" role="alert">
<p class="help-block error-text" ng-message="required">min: 1400 characters max: 14000</p>
<p class="help-block error-text" ng-message="maxlength">min: 1400 characters max: 14000</p>
</div>
您的错误消息也令人困惑,因为您没有设置最小长度但指定了最小长度错误消息。
如果您仍然遇到问题,请尝试将其从ng-maxlength="14000"
更改为maxlength="14000"
,并确保将ngMessages正确注入您的应用程序。
