表单中报表块的跑马灯每次刷新后，隐藏滚动条就会失效，出现滚动条。

5月13日，报表块使用官方JS跑马灯效果+定时刷新控件，刷新后依然出现滚动条

各位看看问题出在哪里？求指导。

JS如下，

var supplierNumber = this.options.form.getWidgetByName("supplierNumber").getValue()

var firstSupplierNumber = parseInt(supplierNumber);

setTimeout(function() {  

    //隐藏报表块report0_c的滚动条（此报表块名为report0_c，根据具体情况修改）  

    $("div[widgetname=REPORT0]").find(".frozen-north")[0].style.overflow = "hidden";  

    $("div[widgetname=REPORT0]").find(".frozen-center")[0].style.overflow = "hidden";  

}, 1000);  

window.flag = true;  

//鼠标悬停，滚动停止    

setTimeout(function() {  

    var old = -1;  

    var interval = setInterval(function() {  

        if(window.flag) {  

            currentpos = $("div[widgetname=REPORT0]").find(".frozen-center")[0].scrollTop;  

            if(currentpos == old) {  

                $("div[widgetname=REPORT0]").find(".frozen-center")[0].scrollTop = 0;  

            } else {  

                old = currentpos;  

                //以25ms的速度每次滚动1PX    

                $("div[widgetname=REPORT0]").find(".frozen-center")[0].scrollTop = currentpos + 1;  

            }  

        }  

    }, 25); 

}, 1000);

var form = this.options.form;  

setInterval(function() {   

form.getWidgetByName('REPORT0').gotoPage(1,"{}",true);

$("div[widgetname=REPORT0]").find(".frozen-north")[0].style.overflow = "hidden";

$("div[widgetname=REPORT0]").find(".frozen-center")[0].style.overflow = "hidden"; 

var lastSupplierNumber = parseInt(_g().options.form.getWidgetByName("report0").element.find("td[id^=A1-]").text());

if (lastSupplierNumber != firstSupplierNumber) {

location.reload();

}

}, 10000); //刷新报表块report0  10s刷新一次
