js文字无缝滚动(js文字左右无缝滚动)
js无缝滚动，现要求：滚动条数少于3条，则停止滚动。超过三条，便自动滚动。请大神帮忙解决一下
div id="scroll_div" class="ks_pic"

scroll_div.scrollTop-=scroll_begin.offsetHeight
else
scroll_div.scrollTop++

html/js 使用marquee标签，怎么可以做到无缝滚动
需要js的配合一下是一个非常好用的一个html代码,可以试试

js无缝滚动，有什么错误？
无缝滚动通常采用一个源版块，一个复制版块，两块并排合成一个主体，在一个较小范围的母版块里并排滚动。假设向上滚动那么js每隔几十毫秒设置主体头部减一js判断当版块2的头部减母版块的头部小于等于零时就设置版块主体头部等零，这样就实现了一个循环如果你的判断有误或者错误赋值或者这个主体总长还没有母版块长就会失灵。
js 实现文字多行多列无缝 循环滚动 且带停顿的
恩，可以百度搜索下“MSClass (Class Of Marquee Scroll通用不间断滚动JS封装类)”这个JS封装类有你要的效果，调用起来也很方便，希望可以帮到你。
