一张决策报表里，我做了3个报表块，需要将他们有跑马灯的效果，report1和report2没问题，可是report3不行，请问是什么原因？report1:
setTimeout(function() {
//隐藏报表块report0的滚动条（此报表块名为report0，根据具体情况修改）
$("div").find(".frozen-north").style.overflow = "hidden";
$("div").find(".frozen-center").style.overflow = "hidden";
}, 1000);
window.flag = true;
//鼠标悬停，滚动停止
setTimeout(function() {
$(".frozen-center").mouseover(function() {
window.flag = false;
});
//鼠标离开，继续滚动
$(".frozen-center").mouseleave(function() {
window.flag = true;
});
var old = -1;
var interval = setInterval(function() {
if(window.flag) {
currentpos = $(".frozen-center").scrollTop;
if(currentpos == old) {
$(".frozen-center").scrollTop = 0;
} else {
old = currentpos;
//以25ms的速度每次滚动1.5PX
$(".frozen-center").scrollTop = currentpos + 1.5;
}
}
}, 25);
}, 1000);
report2:
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").find(".frozen-north").style.overflow = "hidden";
$("div").find(".frozen-center").style.overflow = "hidden";
}, 1000);
window.flag = true;
//鼠标悬停，滚动停止
setTimeout(function() {
$(".frozen-center").mouseover(function() {
window.flag = false;
});
//鼠标离开，继续滚动
$(".frozen-center").mouseleave(function() {
window.flag = true;
});
var old = -1;
var interval = setInterval(function() {
if(window.flag) {
currentpos = $("div").find(".frozen-center").scrollTop;
if(currentpos == old) {
$("div").find(".frozen-center").scrollTop = 0;
} else {
old = currentpos;
//以25ms的速度每次滚动1.5PX
$("div").find(".frozen-center").scrollTop = currentpos + 1.5;
}
}
}, 25);
}, 1000);
report3(和report2一样)
