微信小程序开发—(一)全局配置

来源：互联网发布：执信软件编辑：程序博客网时间：2024/06/06 17:37

一.app.json

使用app.json文件来对微信小程序进行全局配置，决定页面文件的路径、窗口表现、设置网络超时时间、设置多 tab 等.

注意在.json不能注释，否则会出错。

二.工具栏tabBar

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

tabBar 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

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": "热映"}, {"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}

图标可以放在与pages同级，文件命名可是自定。

app.json中其他属性：可以查看手册，里面有详解
