這篇文章主要介紹了微信小程序開發(fā)實(shí)現(xiàn)的選項(xiàng)卡(窗口頂部/底部TabBar)頁(yè)面切換功能,結(jié)合圖文與實(shí)例形式詳細(xì)分析了微信小程序選項(xiàng)卡切換相關(guān)操作實(shí)現(xiàn)技巧,需要的朋友可以參考下

本文實(shí)例講述了微信小程序開發(fā)實(shí)現(xiàn)的選項(xiàng)卡(窗口頂部/底部TabBar)頁(yè)面切換功能。分享給大家供大家參考，具體如下：

微信小程序開發(fā)中選項(xiàng)卡.在android中選項(xiàng)卡一般用fragment,到了小程序這里瞬間懵逼了.

總算做出來(lái)了.分享出來(lái)看看.

先看效果:

再上代碼:

1.index.wxml

<!--index.wxml-->
<view class="swiper-tab">
  <view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">哈哈</view>
  <view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">呵呵</view>
  <view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">嘿嘿</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
  <!-- 我是哈哈 -->
  <swiper-item>
   <view>我是哈哈</view>
  </swiper-item>
  <!-- 我是呵呵 -->
  <swiper-item>
   <view>我是呵呵</view>
  </swiper-item>
  <!-- 我是嘿嘿 -->
  <swiper-item>
   <view>我是嘿嘿</view>
  </swiper-item>
</swiper>

2.index.wxss

/**index.wxss**/
.swiper-tab{
  width: 100%;
  border-bottom: 2rpx solid #777777;
  text-align: center;
  line-height: 80rpx;}
.swiper-tab-list{ font-size: 30rpx;
  display: inline-block;
  width: 33.33%;
  color: #777777;
}
.on{ color: #da7c0c;
  border-bottom: 5rpx solid #da7c0c;}
.swiper-box{ display: block; height: 100%; width: 100%; overflow: hidden; }
.swiper-box view{
  text-align: center;
}

3.index.js

//index.js
//獲取應(yīng)用實(shí)例
var app = getApp()
Page( {
 data: {
  /**
    * 頁(yè)面配置
    */
  winWidth: 0,
  winHeight: 0,
  // tab切換
  currentTab: 0,
 },
 onLoad: function() {
  var that = this;
  /**
   * 獲取系統(tǒng)信息
   */
  wx.getSystemInfo( {
   success: function( res ) {
    that.setData( {
     winWidth: res.windowWidth,
     winHeight: res.windowHeight
    });
   }
  });
 },
 /**
   * 滑動(dòng)切換tab
   */
 bindChange: function( e ) {
  var that = this;
  that.setData( { currentTab: e.detail.current });
 },
 /**
  * 點(diǎn)擊tab切換
  */
 swichNav: function( e ) {
  var that = this;
  if( this.data.currentTab === e.target.dataset.current ) {
   return false;
  } else {
   that.setData( {
    currentTab: e.target.dataset.current
   })
  }
 }
})

之前沒有上傳代碼.這是下圖的代碼

這樣一個(gè)類似viewpage的頂部選項(xiàng)卡就出來(lái)了.

微信小程序開發(fā)中窗口底部tab欄切換頁(yè)面很簡(jiǎn)單很方便.

代碼:

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": "首頁(yè)",
    "pagePath": "pages/index/index",
    "iconPath": "images/home.png",
    "selectedIconPath": "images/home-actived.png"
   },
   {
    "text": "目錄",
    "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(yè)面路徑.iconPath是圖片路徑，icon 大小限制為40kb.
selectedIconPath:選中時(shí)的圖片路徑，icon 大小限制為40kb

tab Bar的最多5個(gè),最少2個(gè).

在pages目錄下寫好頁(yè)面即可切換.

希望本文所述對(duì)大家微信小程序開發(fā)有所幫助。
