接下来介绍页面代码：

控制切换的Tab

<view class="swiper-tab">
    <view class="swiper-tab-item {{currentTab==0?'active':''}}" data-current="0" bindtap="clickTab">做什么</view>
    <view class="swiper-tab-item {{currentTab==1?'active':''}}" data-current="1" bindtap="clickTab">推荐站点</view>
    <view class="swiper-tab-item {{currentTab==2?'active':''}}" data-current="2" bindtap="clickTab">作者</view>
  </view>

要切换的内容：

<view class = "{{currentTab == 0 ? 'show':'hidden'}}" >
    <scroll-view>
      <text>暂无内容1</text>
    </scroll-view>
  </view>
  <view class = "{{currentTab == 1 ? 'show':'hidden'}}" >
    <scroll-view>
      <text>暂无内容2</text>
    </scroll-view>
  </view>
  <view class = "{{currentTab == 2 ? 'show':'hidden'}}">
    <scroll-view>
      <text>暂无内容3</text>
    </scroll-view>
  </view>

js触发事件

//点击切换
  clickTab: function (e) {
    var that = this;
    if (this.data.currentTab === e.target.dataset.current) {
      return false;
    } else {
      that.setData({
        currentTab: e.target.dataset.current,
      })
    }
