微信小程序tabBar

在根目录的app.json中添加tabBar，示例如下

{
  "pages": [
    "pages/index/index",
    "pages/logs/logs",
    "pages/scanning/scanning"
  ],
  "window": {
    "backgroundTextStyle": "light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "WeChat",
    "navigationBarTextStyle": "black"
  },
  "tabBar": {
    "color": "#a9b7b7",
    "selectedColor": "#11cd6e",
    "borderStyle": "white",
    "list": [
      {
        "selectedIconPath": "images/11.png",
        "iconPath": "images/11.png",
        "pagePath": "pages/index/index",
        "text": "首页"
      },
      {
        "selectedIconPath": "images/11.png",
        "iconPath": "images/11.png",
        "pagePath": "pages/logs/logs",
        "text": "日志"
      }
    ]
  }
}

注：在小程序中，最后一个括号后面不能带','，否则会出现编译错误
