在进行微信小程序开发的时候我们会经常遇到底部tab栏的操作，微信小程序官方也为我们提供了简单便捷的配置方法，举例出来供大家参考：

在全局的app.json页面中增加tabbar键值对：

代码如下：

{

"pages":[

"pages/index/index",

"pages/cart/cart",

"pages/user/user"

],

"window":{

"backgroundTextStyle":"light",

"navigationBarBackgroundColor": "#F58233",

"navigationBarTitleText": "家居电商",

"navigationBarTextStyle":"white"

},

"tabBar": {

"list": [{

"pagePath": "pages/index/index",

"text": "推荐",

"iconPath": "/images/No-orders.png",

"selectedIconPath": "/images/fail.png"

},{

"pagePath": "pages/cart/cart",

"text": "购物车",

"iconPath": "/images/[email protected]",

"selectedIconPath": "/images/[email protected]"

},{

"pagePath": "pages/user/user",

"text": "我",

"iconPath": "/images/defaultAvatar.png",

"selectedIconPath": "/images/[email protected]"

}]

}

}
