小程序官方自定义tabbar组件使用

1.首先在app.js配置 方便全局获取

 //收银台菜单配置
      cacherList: [{
        "pagePath": "/packageThirst/pages/cacher/shop/index",
        "text": "采货",
        "iconPath": "/foots/icon/cash_1.png",
        "selectedIconPath": "/foots/icon/cash_1_select.png"
      },
      {
        "pagePath": "/packageThirst/pages/cacher/sell/index",
        "text": "卖货",
        "iconPath": "/foots/icon/cash_2.png",
        "selectedIconPath": "/foots/icon/cash_2_select.png",
      },
      {
        "pagePath": "/packageFour/pages/partner/shopincome/index",
        "text": "资金",
        "iconPath": "/foots/icon/cash_3.png",
        "selectedIconPath": "/foots/icon/cash_3_select.png"
      },
      {
        "pagePath": "/packageThirst/pages/cacher/analyse/index",
        "text": "分析",
        "iconPath": "/foots/icon/cash_4.png",
        "selectedIconPath": "/foots/icon/cash_4_select.png"
      }
      ],

　　　　

  tabChange: function(e) {

    console.log('tab change', e.detail.item.pagePath)

    wx.redirectTo({

      url: e.detail.item.pagePath

    })

  },

 2.页面data数据获取

 data: {
    list: getApp().globalData.cacherList,
  },

3.页面wxml文件

<mp-tabbar class="tabla_cls" list="{{list}}" bindchange="tabChange" current="0"></mp-tabbar>

4.页面js文件

 tabChange(e) {
    getApp().tabChange(e);
  },

5.json

 "usingComponents": {
    "mp-tabbar": "../../../components/tabbar/tabbar",
  },
