JQuery 锚点连接屏幕滚动

直接上代码：

<!DOCTYPE html>
<html class="no-js" lang="en"><head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
        <meta charset="utf-8">
        <script src="jquery1_files/jquery.js"></script>

            </head>
<script type="text/javascript">
$(function(){
    
       $(window).scroll(function(){
             //为页面添加页面滚动监听事件
                  var wst =  $(window).scrollTop() //滚动条距离顶端值
                 for (i=1; i<6; i++){             //加循环
                  if($("#a"+i).offset().top<=wst){ //判断滚动条位置
                     $('#nav a').css("background-color","white"); //清除c类
                     $("#a"+i+i).css("background-color","red");    //给当前导航加c类
                     }
                 }         
      })
       $('#nav a').click(function(){
        $('#nav a').css("background-color","white");//清除c类
        $(this).css("background-color","red");//给当前导航加c类
        });
});
</script>
<div id="nav" style="position:fixed;width:500px;height:200px; top:10px;right:10px;" >
