微信小程序中的TabBar可以通过app.json文件进行配置。在app.json文件中,通过"tabBar"字段来配置TabBar的相关信息。具体配置方式如下:
{
"tabBar": {
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "images/tabbar/home.png",
"selectedIconPath": "images/tabbar/home_selected.png"
},
{
"pagePath": "pages/category/category",
"text": "分类",
"iconPath": "images/tabbar/category.png",
"selectedIconPath": "images/tabbar/category_selected.png"
},
{
"pagePath": "pages/cart/cart",
"text": "购物车",
"iconPath": "images/tabbar/cart.png",
"selectedIconPath": "images/tabbar/cart_selected.png"
},
{
"pagePath": "pages/mine/mine",
"text": "我的",
"iconPath": "images/tabbar/mine.png",
"selectedIconPath": "images/tabbar/mine_selected.png"
}
]
}
}
在对应的页面路径下创建对应的页面文件,并在页面文件中进行相关的开发和渲染。
配置完成后,在小程序启动后,就会显示对应的TabBar,并可以实现页面之间的切换和导航。
