/**************************************************
函数名：ScrollTimeID
作  用：无间断滚动
参  数：DIvID:滚动所在层的ID, Direct:滚动的方向,1:垂直向上 2:垂直向下 3:水平向左 4:水平向右 Speed:滚动的速度 HtmStr:滚动的内容(如果为空,表明内容由asp写入,注意,asp只写入一半,二htm是全部写入DivID+'a'和DivID+'b').
'		ParaStr:相关参数, 格式为:无间断滚动类型|滚动一周后的调用的函数名|滚动步长
'		无间隔滚动类型: 如果为0表示当前滚动为持续无间断滚动,如果为其它数字,表示当前滚动为间断无间断滚动,当一屏滚动完毕后,停留一定时间后,再滚动到下一屏,两者在程序上的区别在于:前者是根据滚动方向的不同由程序产生两个内容同为HtmStr,但位置不同的ID分别为a和b的表格,后者则两个表格在页面制作时已做好,ID分别为a和b
返回值：
