<view class="tab">  
 <view class="tab-left" bindtap="tabFun">  
   <view class="{{tabArr.curHdIndex=='0'? 'active' : ''}}" id="tab-hd01" data-id="0">tab-hd01</view>  
   <view class="{{tabArr.curHdIndex=='1'? 'active' : ''}}" id="tab-hd02" data-id="1">tab-hd01</view>  
   <view class="{{tabArr.curHdIndex=='2'? 'active' : ''}}" id="tab-hd03" data-id="2">tab-hd01</view>  
   <view class="{{tabArr.curHdIndex=='3'? 'active' : ''}}" id="tab-hd04" data-id="3">tab-hd01</view>  
 </view>  

 <view class="tab-right">  
   <view class="right-item {{tabArr.curBdIndex=='0'? 'active' : ''}}">tab-bd01</view>  
   <view class="right-item {{tabArr.curBdIndex=='1'? 'active' : ''}}">tab-bd02</view>  
   <view class="right-item {{tabArr.curBdIndex=='2'? 'active' : ''}}">tab-bd03</view>  
   <view class="right-item {{tabArr.curBdIndex=='3'? 'active' : ''}}">tab-bd04</view>  
 </view>  
</view>  

demo.js：

Page( {  
  data: {  
    tabArr: {  
      curHdIndex: 0,  
      curBdIndex: 0  
    },  
  },  
  tabFun: function(e){  
    //获取触发事件组件的dataset属性  
    var _datasetId=e.target.dataset.id;  
    console.log("----"+_datasetId+"----");  
    var _obj={};  
    _obj.curHdIndex=_datasetId;  
    _obj.curBdIndex=_datasetId;  
    this.setData({  
      tabArr: _obj  
    });  
  },  
  onLoad: function( options ) {  
    alert( "------" );  
  }  
});

demo.wxss：

.tab{  
   display: flex;  
   flex-direction: row;  
}  
.tab-left{  
    200rpx;  
   line-height: 160%;  
   border-right: solid 1px gray;  
}  
.tab-left view{  
   border-bottom: solid 1px red;  
}  
.tab-left .active{  
   color: #f00;  
}  
.tab-right{  
   line-height: 160%;
