Vue2通知提醒框（Notification）

项目相关依赖版本信息

可自定义设置以下属性：

自动关闭的延时时长（duration），单位ms，默认4500ms
消息从顶部弹出时，距离顶部的位置（top），单位像素px，默认24px
消息从底部弹出时，距离底部的位置（bottom），单位像素px，默认24px
弹出位置（placement），可选：左上topLeft，右上topRight（默认），左下bottomLeft，右下bottomRight

调用时可选以下五个方法对应五种不同样式：

this.$refs.notification.open(notification) // 默认使用
this.$refs.notification.info(notification) // info调用
this.$refs.notification.success(notification) // success调用
this.$refs.notification.error(notification) // error调用
this.$refs.notification.warning(notification) // warning调用

五种样式效果如下图：

open()调用：

info()调用：

success()调用：

error()调用：

warning()调用：

①创建通知提醒框组件Notification：

②在要使用的页面引入：

<Notification

      :top="30"
      @close="onClose" />

        description: 'This is the content of the notification. This is the content of the notification. This is the content of the notification.'
      }
      this.$refs.notification.open(notification) // 默认使用
      // this.$refs.notification.info(notification) // info调用
      // this.$refs.notification.success(notification) // success调用
      // this.$refs.notification.error(notification) // error调用
      // this.$refs.notification.warn(notification) // warning调用
},
onClose () { // 点击默认关闭按钮时触发的回调函数
      console.log('关闭notification')
}
