隐藏滚动条并且自动滚动的js：

setTimeout(function() {

AutoScroll(["REPORT0", "REPORT4", "REPORT5"]); 

//定义需要跑马灯效果的报表块名字，兼容大小写

}, 2000);

function AutoScroll(e) {

for (i = 0; i < e.length; i++) {

(function(e, i) {

scroll(e, i);

})(e, i);

}

}

function scroll(e, i) {

var $report = $("div[widgetname=" + e[i].toUpperCase() + "]");

//获取对应report的div元素

var $scroll;

if ($report.find(".frozen-center").length != 0) {

$scroll = $report.find(".frozen-center");

} else if ($report.find(".scrollDiv").length != 0) {

$scroll = $report.find(".scrollDiv");

} else {

$scroll = $report.find(".reportContent");

}

//判断是否冻结以及是否安装自定义滚动条插件

var flag = eval("window.flag" + i);

//设置全局flag，控制悬停

if (interval) {

clearInterval(interval);

}

//清除定时器，避免越滚越快

var interval = eval("window.interval" + i);

$report.find("#frozen-center").css('overflow-x', 'hidden');

$report.find("#frozen-center").css('overflow-y', 'hidden');

$report.find("#frozen-north").css('overflow-x', 'hidden');

$report.find("#frozen-north").css('overflow-y', 'hidden');

//冻结情况下隐藏滚动条

$report.find(".reportContent").css('overflow-y', 'hidden');

$report.find(".reportContent").css('overflow-x', 'hidden');

//非冻结情况下隐藏滚动条

flag = true;

$scroll.mouseover(function() {

flag = false;

                $report.find("#frozen-center").css('overflow-x', 'hidden');

$report.find("#frozen-center").css('overflow-y', 'auto');

$report.find("#frozen-north").css('overflow-x', 'hidden');

$report.find("#frozen-north").css('overflow-y', 'auto');

})

//鼠标悬浮，滚动停止

$scroll.mouseleave(function() {

flag = true;

$report.find("#frozen-center").css('overflow-x', 'hidden');

$report.find("#frozen-center").css('overflow-y', 'hidden');

$report.find("#frozen-north").css('overflow-x', 'hidden');

$report.find("#frozen-north").css('overflow-y', 'hidden');

})

//鼠标离开，继续滚动

var old = -1;

interval = setInterval(function() {

if (flag) {

currentpos = $scroll[0].scrollTop;

//获取距顶部距离

if (currentpos == old) {

$scroll[0].scrollTop = 0;

//若已到达底部，则重置

} else {

old = currentpos;

$scroll[0].scrollTop = currentpos + 1.0;

//若未到达底部，则向下移动1.0像素

}

}

}, 100);

//以100ms的频率执行

}
