元素：
元素距离顶部距离document.getElementById(id).offset().top 元素距离左边距离document.getElementById(id).offset().left 可根据需求改为Jquery滚动条：
$(window).scrollTop(); //得到滚动条距离顶部的距离。 //设置滚动条距离顶部或底部的距离，保持滚动条状态等$(window).scroll( function() { var screenheight = window.screen.availHeight; //获取屏幕高 $(window).scrollTop( document.body.clientHeight-120-screenheight);//移动到据底部120px } );
