bootstrap的scrollspy.js,可以参考下

这是我很久以前写的,应该能行。
<code>//jquery v1.8.3 $(window).scroll(scrollto); //判断滚动条滚动了,执行scrollto() function scrollto(){ var scroll_top = $(window).scrollTop(); //获取到滚动条距离顶部的位置(应该是,嘿嘿),你算好滚动到工作经历是多少的数值,然后进行if判断,大于这个数值了就对左侧列表的原点进行操作。 $(".float").stop().animate({top:scroll_top}); //这是我要进行的操作 } </code>
