微信小程序开发中窗口底部tab栏切换页面很简单很方便.

代码:

1.app.json

//app.json
{
  "pages":[
    "pages/index/index",
    "pages/logs/logs"
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#999999",
    "navigationBarTitleText": "tab",
    "navigationBarTextStyle":"white"
  },
   "tabBar": {
    "color": "#ccc",
    "selectedColor": "#35495e",
    "borderStyle": "white",
    "backgroundColor": "#f9f9f9",
    "list": [
      {
        "text": "首页",
        "pagePath": "pages/index/index",
        "iconPath": "images/home.png",
        "selectedIconPath": "images/home-actived.png"
      },
      {
        "text": "目录",
        "pagePath": "pages/catalogue/catalogue",
        "iconPath": "images/note.png",
        "selectedIconPath": "images/note-actived.png"
      },
      {
        "text": "我的",
        "pagePath": "pages/mine/mine",
        "iconPath": "images/profile.png",
        "selectedIconPath": "images/profile-actived.png"
      }
    ]
  }
}

pagePath是页面路径.iconPath是图片路径，icon 大小限制为40kb.

selectedIconPath:选中时的图片路径，icon 大小限制为40kb

tab Bar的最多5个,最少2个.

在pages目录下写好页面即可切换.
