微信小程式開發之選項卡(視窗底部TabBar)頁面切換實現

本文主要介紹了微信小程式開發之選項卡(視窗底部TabBar)頁面切換的相關知識。具有很好的參考價值。下面跟著小編一起來看下吧

微信小程式開發中視窗底部tab欄切換頁面很簡單很方便.

#程式碼:

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是頁面路徑.iconPath是圖片路徑，icon 大小限制為40kb.

selectedIconPath:選取時的圖片路徑，icon 大小限制為40kb

tab Bar的最多5個,最少2個.

#在pages目錄下寫好頁面即可切換.
