微信小程序之底部导航栏——tabBar

先建两个目录，待会我们跳转用！

在app.json中，别忘了要添加目录！

app.json中的配置

"tabBar": {
    "list": [{
      "pagePath": "pages/index/index",
      "text": "微笑",
      "iconPath": "pages/index/img/Smile.png",
      "selectedIconPath": "pages/index/img/Smile_select.png"
    },
    {
      "pagePath": "pages/tabOne/tabOne",
      "text": "购物车",
      "iconPath": "pages/index/img/cart.png",
      "selectedIconPath": "pages/index/img/cart_select.png"
    },
    {
      "pagePath": "pages/tabTwo/tabTwo",
      "text": "所有",
      "iconPath": "pages/index/img/all.png",
      "selectedIconPath": "pages/index/img/all_select.png"
    }]
  }

不过好像字木有变化哦！

还要添加一行代码！

 

就完成啦！
