一.app.json

使用app.json文件來對微信小程序進行全局配置，決定頁面文件的路徑、窗口表現(xiàn)、設(shè)置網(wǎng)絡(luò)超時時間、設(shè)置多 tab 等.

注意在.json不能注釋，否則會出錯。

二.工具欄tabBar

如果我們的小程序是一個多 tab 應(yīng)用（客戶端窗口的底部或頂部有 tab 欄可以切換頁面），那么我們可以通過 tabBar 配置項指定 tab 欄的表現(xiàn)，以及 tab 切換時顯示的對應(yīng)頁面。

tabBar 是一個數(shù)組，只能配置最少2個、最多5個 tab，tab 按數(shù)組的順序排序

app.json中

{  "pages": ["pages/index/index",     "pages/coming/coming",     "pages/search/search",     "pages/top/top"    ],  "window": {   "navigationBarBackgroundColor": "#47a86c",   "navigationBarTextStyle": "white",   "navigationBarTitleText": "小程序案例",   "backgroundColor": "#fff",   "backgroundTextStyle": "dark"  },  "tabBar": {   "color": "#686868",   "selectedColor": "#47a86c",   "backgroundColor": "#fff",   "list": [{    "pagePath": "pages/index/index",    "iconPath": "dist/images/popular_icon.png",    "selectedIconPath": "dist/images/popular_active_icon.png",    "text": "熱映"   },   {    "pagePath": "pages/coming/coming",    "iconPath": "dist/images/coming_icon.png",    "selectedIconPath": "dist/images/coming_active_icon.png",    "text": "待映"   },   {    "pagePath": "pages/search/search",    "iconPath": "dist/images/search_icon.png",    "selectedIconPath": "dist/images/search_active_icon.png",    "text": "搜索"   },   {    "pagePath": "pages/top/top",    "iconPath": "dist/images/top_icon.png",    "selectedIconPath": "dist/images/top_active_icon.png",    "text": "口碑"   }]  },  "networkTimeout": {   "request": 10000,   "downloadFile": 10000  },  "debug": true }
