使用到的知识——全局配置app.json文件tabBar项

tabBar
如果小程序是一个多 tab 应用(客户端窗口的底部或顶部有 tab 栏可以切换页面),可以通过 tabBar 配置项指定 tab 栏的表现,以及 tab 切换时显示的对应页面。

Tip:
当设置 position 为 top 时,将不会显示 icon
tabBar 中的 list 是一个数组,只能配置最少2个、最多5个 tab,tab 按数组的顺序排序。

这里写图片描述
举个例子

"tabBar": {
"color": "red",
"background": "gray",
"selectedColor": "green",
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "images/miao.png",
"selectedIconPath": "images/miao.png"
},
{
"pagePath": "pages/test/test",
"text": "日志",
"iconPath": "images/miao.png",
"selectedIconPath": "images/miao.png"
}
]
},
"debug": "true",
"networkTimeout": {
"request": 10000,
"downloadFile": 10000
}
}

注意:pagePath里的路径页面一定要在page里写出

"pages": [
    "pages/index/index",
    "pages/login/login",
        "pages/logs/logs",
    "pages/test/test",
    "pages/xiangqing/xiangqing",
    "pages/user/user"

  ],

并且app.json里不可以有注释(微信是个傲娇受!!!!)

符:整个app.json

{
  "pages": [
    "pages/index/index",
    "pages/login/login",
        "pages/logs/logs",
    "pages/test/test",
    "pages/xiangqing/xiangqing",
    "pages/user/user"

  ],
  "window": {
    "backgroundTextStyle": "light",
    "navigationBarBackgroundColor": "#fff",
    "navigationBarTitleText": "一只大喵喵",
    "navigationBarTextStyle": "black"
  },
  "tabBar": {
    "color": "red",
    "background": "gray",
    "selectedColor": "green",
    "list": [
      {
        "pagePath": "pages/index/index",
        "text": "首页",
        "iconPath": "images/miao.png",
        "selectedIconPath": "images/miao.png"
      },
      {
        "pagePath": "pages/test/test",
        "text": "日志",
        "iconPath": "images/miao.png",
        "selectedIconPath": "images/miao.png"
      }
    ]
  },
  "debug": "true",
  "networkTimeout": {
    "request": 10000,
    "downloadFile": 10000
  }
}
