微信小程序中的TabBar可以通過app.json文件進行配置。在app.json文件中,通過"tabBar"字段來配置TabBar的相關信息。具體配置方式如下:
{
"tabBar": {
"list": [
{
"pagePath": "pages/index/index",
"text": "首頁",
"iconPath": "images/tabbar/home.png",
"selectedIconPath": "images/tabbar/home_selected.png"
},
{
"pagePath": "pages/category/category",
"text": "分類",
"iconPath": "images/tabbar/category.png",
"selectedIconPath": "images/tabbar/category_selected.png"
},
{
"pagePath": "pages/cart/cart",
"text": "購物車",
"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"
}
]
}
}
在對應的頁面路徑下創建對應的頁面文件,并在頁面文件中進行相關的開發和渲染。
配置完成后,在小程序啟動后,就會顯示對應的TabBar,并可以實現頁面之間的切換和導航。
