微信小程序开发中窗口底部tab栏切换页面很简单很方便.
代码:
1.app.json
//app.json { "pages":[ "pages/index/index", "pages/logs/logs" ], "window":{ "backgroundTextStyle":"light", "navigationBarBackgroundColor": "#999999", "navigationBarTitleText": "tab", "navigationBarTextStyle":"white" }, "tabBar": { "color": "#ccc", "selectedColor": "#35495e", "borderStyle": "white", "backgroundColor": "#f9f9f9", "list": [ { "text": "首页", "pagePath": "pages/index/index", "iconPath": "images/home.png", "selectedIconPath": "images/home-actived.png" }, { "text": "目录", "pagePath": "pages/catalogue/catalogue", "iconPath": "images/note.png", "selectedIconPath": "images/note-actived.png" }, { "text": "我的", "pagePath": "pages/mine/mine", "iconPath": "images/profile.png", "selectedIconPath": "images/profile-actived.png" } ] } }
pagePath是页面路径.iconPath是图片路径，icon 大小限制为40kb.
selectedIconPath:选中时的图片路径，icon 大小限制为40kb
tab Bar的最多5个,最少2个.
在pages目录下写好页面即可切换.
