两层滚动条互补干扰

  <div class="zoneDetails-content blockStyle-content layerScroll" 
       onmousewheel="return divScroll(event,this)">

  divScroll:function(event,scroller){
    var k = event.wheelDelta? event.wheelDelta:-event.detail*10;
    scroller.scrollTop = scroller.scrollTop - k;
    return false;
  },

  var DivScroll = function( layerNode ){
    //如果没有这个元素的话，那么将不再执行下去
    if ( !document.querySelector( layerNode ) ) return ;

    this.popupLayer = document.querySelector( layerNode ) ;
    this.startX = 0 ;
    this.startY = 0 ;

    this.popupLayer.addEventListener(‘touchstart‘, function (e) {
      this.startX = e.changedTouches[0].pageX;
      this.startY = e.changedTouches[0].pageY;
    }, false);

    // 仿innerScroll方法
    this.popupLayer.addEventListener(‘touchmove‘, function (e) {

      e.stopPropagation();

      var deltaX = e.changedTouches[0].pageX - this.startX;
      var deltaY = e.changedTouches[0].pageY - this.startY;

      // 只能纵向滚
      if(Math.abs(deltaY) < Math.abs(deltaX)){

        return false;
      }

      if( this.offsetHeight + this.scrollTop >= this.scrollHeight){

          e.preventDefault();
          return false;
        }
      }
      if(this.scrollTop === 0){

          e.preventDefault();
          return false;
        }
      }
      // 会阻止原生滚动
      // return false;
    },false);

  }

  //调用
  var divScroll = new DivScroll(‘.layerNode‘);
