     ul>
div>

            text_roll:['张三金','王五成功邀请小二，获1460阅读基金','是游戏，获基金','XX']
        },
        activeIndex: 0
    }
}，
computed: {
    top() {
      return - this.activeIndex * 2.5 + 'rem';
    }
},
mounted(){
    let _this = this; 
    setInterval(function(){
      if(_this.activeIndex < _this.invit_info.text_roll.length-1) {
        _this.activeIndex +=1;
      } else {
        _this.activeIndex = 0;
      }
    }, 1000);
 },
