能够看到在下面有对应的menu菜单，能够进入首页，足迹和我的界面。

那么是如何实现的呢，下面我把主要代码放上。

{
      "pages":[
        "pages/index/index",
        "pages/logs/logs",
        "pages/my/my"
      ],
      "window":{
        "navigationBarBackgroundColor": "#ffffff",
        "navigationBarTextStyle": "black",
        "navigationBarTitleText": "功能演示",
        "backgroundColor": "#eeeeee",
        "backgroundTextStyle": "light"
      },
      "tabBar": {
        "selecctedColor": "#ffffff",
        "backgroundColor": "#eeeeee",
        "position":"bottom",
        "list": [
          {
            "pagePath": "pages/index/index",
            "text": "首页",
            "iconPath":"pages/img/menuicon/home.png",
            "selectedIconPath":"pages/img/menuicon/home2.png"
          },
          {
           "pagePath": "pages/logs/logs",
            "text": "足迹",
            "iconPath": "pages/img/menuicon/foot.png",
            "selectedIconPath": "pages/img/menuicon/foot2.png" 
          },
          {
            "pagePath": "pages/my/my",
            "text": "我的",
            "iconPath": "pages/img/menuicon/my.png",
            "selectedIconPath": "pages/img/menuicon/my2.png"
          }
        ]
      },
      "networkTimeout": {
        "request": 20000,
        "connectSocket": 20000,
        "uploadFile": 20000,
        "downloadFile": 20000
      }
    }

对应的目录结构如下：
