使用this.setData()动态渲染成功了，不过加了wx.switchTab之后，控制台还是正确输出的，视图层渲染完之后又跳了回去，使用setTimeout对wx.swtichTab延迟也没用，跳转没问题，就是视图层变得混乱了，毫无规律

routeTab(e) {
      var that = this;
      var ind = e.currentTarget.dataset.select;
      // console.log(this.data.list[ind].pagePath);
      for (var i = 0; i < that.data.list.length;i++) {
        // item[i].check = false;
        if (i != ind) {
          var tempFalse = 'list[' + i + '].check';
          that.setData({
            [tempFalse]: false
          });
          console.log(tempFalse, i);


        }
        
      }
      // item[ind].check = true;
      var tempTrue = 'list[' + ind + '].check';
      that.setData({
        [tempTrue]: true
      });



      console.log(tempTrue,ind);
      console.log(that.data.list);
      setTimeout(()=>{
        wx.switchTab({
          url: that.data.list[ind].pagePath,
          
        });
      },100);
      
      
    }
