好久沒有寫東西了 今天寫一個簡單的東西

小程序tab切換 （選項卡功能）

.wxml

<view class="swiper-tab">
  <view class="swiper-tab-item {{currentTab==0?‘active‘:‘‘}}" data-current="0" bindtap="clickTab">111</view>
  <view class="swiper-tab-item {{currentTab==1?‘active‘:‘‘}}" data-current="1" bindtap="clickTab">222
 
</view>
</view>

<swiper current="{{currentTab}}" bindchange="swiperTab" style="height:{{swiperHeight}}rpx;">
  <swiper-item>
    <view class=‘ycy‘>
      <text>111111</text>
    </view>
  </swiper-item>

  <swiper-item>
    <view class=‘ycy‘
 
>
      <text>222222</text>
    </view>
  </swiper-item>
</swiper>

.js

Page({
  data: {
    currentTab: 0,
  },
  swiperTab: function (e) {
    var that = this;
    that.setData({
      currentTab: e.detail.current
    });
  },
  clickTab: function (e) {
    var that = this
 
;
    if (this.data.currentTab === e.target.dataset.current) {
      return false;
    } else {
      that.setData({
        currentTab: e.target.dataset.current
      })
    }
  },
})
