微信小程序：選項卡頁面切換

1、功能描述

在同一個頁面內實現不一樣展現頁面的切換功能，以下圖所示

 

2、代碼實現

1. index.js

Page({

  /**
   * 頁面的初始數據
   */
  data: {
      currentData : 0,
  },
  /**
   * 生命週期函數--監聽頁面加載
   */
  onLoad: function (options) {
  },
  //獲取當前滑塊的index
  bindchange:function(e){
    const that  = this;
    that.setData({
      currentData: e.detail.current
    })
  },
  //點擊切換，滑塊index賦值
  checkCurrent:function(e){
    const that = this;

    if (that.data.currentData === e.target.dataset.current){
        return false;
    }else{

      that.setData({
        currentData: e.target.dataset.current
      })
    }
  }
})

　　

　　

2. index.wxml

<view class='topTabSwiper'>
    <view class='tab  {{currentData == 0 ? "tabBorer" : ""}}'  data-current = "0" bindtap='checkCurrent'>推薦</view>
    <view class='tab  {{currentData == 1 ? "tabBorer" : ""}}'  data-current = "1" bindtap='checkCurrent'>熱點</view>
    <view class='tab  {{currentData == 2 ? "tabBorer" : ""}}'  data-current = "2" bindtap='checkCurrent'>關注</view>
</view>
<swiper current="{{currentData}}" class='swiper' style="height:600px;" duration="300" bindchange="bindchange">
  <swiper-item><view class='swiper_con'>welcome come to 推薦</view></swiper-item> 
  <swiper-item><view class='swiper_con'>welcome come to 熱點</view></swiper-item>
  <swiper-item><view class='swiper_con'>welcome come to 關注</view></swiper-item>  
</swiper>

　　

3. index.wxss

.tab {
  float: left;
  width: 33.3333%;
  text-align: center;
  padding: 10rpx 0;
}

.topTabSwiper {
  border-top: 1px solid #ccc;
  border-bottom: 1px solid #ccc;
  zoom: 1;
}

.topTabSwiper:after {
  content: "";
  clear: both;
  display: block;
}

.tabBorer {
  border-bottom: 1px solid #f00;
  color: #f00;
}

.swiper {
  width: 100%;
}

.swiper_con {
  text-align: center;
  width: 100%;
  height: 100%;
  padding: 80rpx 0;
}
