相关组件或插件运行时的项目依赖版本信息

项目运行时依赖：vue@^2.6.12 vue-router@3.6.4

项目开发时依赖：less@^4.1.3  less-loader@^5.0.0  vue-template-compiler@^2.6.12

"dependencies": {
    "axios": "^0.27.2",
    "core-js": "^3.6.5",
    "echarts": "^5.3.3",
    "swiper": "5.4.5",
    "vue": "^2.6.12",
    "vue-amazing-selector": "^0.2.6",
    "vue-lazyload": "1.3.3",
    "vue-router": "3.6.4",
    "vuedraggable": "^2.24.3"
},
"devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.15",
    "@vue/cli-plugin-eslint": "~4.5.15",
    "@vue/cli-service": "~4.5.15",
    "@vue/eslint-config-standard": "^5.1.2",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-import": "^2.20.2",
    "eslint-plugin-node": "^11.1.0",
    "eslint-plugin-promise": "^6.0.1",
    "eslint-plugin-standard": "^5.0.0",
    "eslint-plugin-vue": "^6.2.2",
    "less": "^4.1.3",
    "less-loader": "^5.0.0",
    "vue-template-compiler": "^2.6.12",
    "webpack-bundle-analyzer": "^4.6.1",
    "babel-plugin-transform-remove-console": "^6.9.4",
    "compression-webpack-plugin": "^6.0.2"
}

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：

<template>
  <div :class="['m-notification-wrap', placement]" :style="`top: ${placement.includes('top') ? top : ''}px; bottom: ${placement.includes('bottom') ? bottom : ''}px;`">
      <transition name="slide-fade" v-for="(data, index) in notificationData" :key="index">
        <div class="m-notification" v-if="showNotification[index]">

    }
  }

②在要使用的页面引入：

<Notification
      ref="notification"
      placement="topRight"
      :duration="null"
      :top="30"
      @close="onClose" />
import Notification from '@/components/Notification'
components: {
    Notification
}
onShowNotification () {
      const notification = {
        title: 'Notification Title',
        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.warning(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')
}
