这个视频点击开始的播放几秒就缩回去了
我想要的结果是不缩回去


------解决方案--------------------
很难想像，1楼你就是靠这么多的疑问句得到了星星？

if (popTop > 1720) {
clearTimeout(mytime);
oPopup.hide();
return;
} 
popTop += 10;
var mytime = setTimeout("popshow();", 50);
这样累积到了大于1720自然就隐藏了。
不知楼主到底想怎样。事情交待不清楚。简单说要不隐藏，就或者把上面的IF里面的隐藏处理去掉，或者把下面的popTop += 10;去掉。
