1、前言

我们先来看下效果图：

注意：

• 导航栏数量最多5个，最少两个。

2、图标准备

阿里图标库 http://www.iconfont.cn/collections/show/29
我们进入该网站，选择我们所需要的图标，点击下方的下载按钮，比如首页，下载对应的png文件。

3、小程序tabbar设置

在pages.json文件中配置如下代码：

{
  "easycom": {
    "^u-(.*)": "@/uni_modules/uview-ui/components/u-$1/u-$1.vue"
  },
  "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
    {
      "path": "pages/home/home",
      "style": {
        "navigationBarTitleText": "首页",
        "enablePullDownRefresh": false
      }
    },
    {
      "path": "pages/monitor/monitor",
      "style": {
        "navigationBarTitleText": "监控",
        "enablePullDownRefresh": false
      }
    },
    {
      "path": "pages/alarm/alarm",
      "style": {
        "navigationBarTitleText": "告警",
        "enablePullDownRefresh": false
      }
    },
    {
      "path": "pages/user/user",
      "style": {
        "navigationBarTitleText": "",
        "navigationStyle": "custom"
      }
    }
  ],
 "tabBar": {

    "selectedColor": "#1296db",
    "borderStyle": "black",
    "backgroundColor": "#ffffff",
    "list": [{
        "pagePath": "pages/home/home",

        "selectedIconPath": "static/img/tabbar/home_active.png",
        "text": "首页"
      },
      {
        "pagePath": "pages/monitor/monitor",
        "iconPath": "static/img/tabbar/monitor.png",
        "selectedIconPath": "static/img/tabbar/monitor_active.png",
        "text": "监控"
      },
      {
        "pagePath": "pages/alarm/alarm",

        "selectedIconPath": "static/img/tabbar/alarm_active.png",
        "text": "告警"
      },
      {
        "pagePath": "pages/user/user",
        "iconPath": "static/img/tabbar/my.png",
        "selectedIconPath": "static/img/tabbar/my_active.png",
        "text": "我的"
      }
    ]
  },

  "globalStyle": {
    "navigationBarTextStyle": "black",
    "navigationBarTitleText": "uni-app",
    "navigationBarBackgroundColor": "#F8F8F8",
    "backgroundColor": "#F8F8F8"
