mui div滾動阻止觸發下拉刷新

function orderListScroll () {
        var _orderObj = document.querySelector('.circulation-loan-list') //div滾動的外層div
        _orderObj.addEventListener('scroll', function (e) {if (_orderObj.scrollTop > 10) { 
                plus.webview.currentWebview().setPullToRefresh({support:false});
            } else { //div滾動到最上面才觸發下拉刷新
                plus.webview.currentWebview().setPullToRefresh({support:true,style:"circle"})
            }
        })
    }
