js控制滚动条 滚动指定距离
想要移动效果需要结合定时器来做吧。
setInterval来实现。或者用jq的animate方法。

Q1: js,鼠标上下滑轮或者拉动滚动条触发事件
window.onmousewheel = function(){ //触发滚轮事件
}
window.onscroll = function(){ //滚动条事件
}
//其实你的问题直接使用判断滚动条应该就可以了，但是如果一定要拖动滚动条才执行事件，我们可以通过获取鼠标位置来模拟
var a = document.getElementsByTagName("html")[0];
window.onmousemove = function(){
//一般默认滚动条12px宽，当鼠标位于浏览器窗口右边12px内按下鼠标可以视为拖动滚动条
if(innerWidth - event.clientX 12){
a.onmousedown = function(){
console.log(1);
}
}else{
a.onmousedown = null;
}
}

Q3: js如何在滑动条下拉的时候固定住一行不动
很多时候，需要对div进行固定，比如在线咨询模块，这就需要固定div在显示页面的位置，而不能随滚动条滚动。
思路：将需要固定的div做成悬浮框，目的是能和别的div块重合，然后当触发滚动条事件，动态改变div坐标。
代码：
jsp中：
body
div style="position: absolute;z-index:90" id="div1"我不动/div
div我动div
/body
//有的将position设置成fixed,我试了试效果不如position好,设置z-index，向里的深度，我这儿设置90，你要覆盖几个div，设置数大于那个数就行。
js中：
我这儿用jquery写。
$(document).ready(function(){
$(window).scroll(function(){//滚动时触发函数
$("#div1").css("top",$(document).scrollTop());//将滚动条高度赋给悬浮框。
})
})
导入jquery库，效果就出来了。
