The jquery code is as follows:

var page=0;//翻屏变量，初始第一屏
var shakStaute = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象
$(function(){
  var starttime = 0,
    endtime = 0;
  $("body").mousewheel(function(event, delta) {
    starttime = new Date().getTime(); //记录翻屏的初始时间
    if (delta < 0&& page>=0 && page<=$(".content .divsame").length-2) { 
      if (shakStaute>=0 &&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏
        shakStaute=1;
        page++;
        renderPage(page,true); //翻屏函数
        endtime = new Date().getTime();  //记录翻屏的结束时间
      }
    } else if (delta>0 && page>=1 && shakStaute==1 && (starttime == 0 || (endtime - starttime) <= -500)) {  
      page--;

    $(".divsame").css({'height':div_height});
    $('.content').animate({top:-page*div_height }, 100);

Let’s look at another example

Pay attention to the js loaded in the head, the jquery library, and the index.js that mousewheel.js has implemented

<!doctype html>

<style>
  body{padding:0;margin:0; overflow:hidden }
  ul{list-style:none;}
  .div_01,.div_02,.div_03,.div_04{width:100%;margin:0 auto; text-align: center;}
  .div_01{background: #b20909;}
  .div_02{background: #0941b2;}
  .div_03{background: #2db209;}
  .div_04{background: #b29c09;}
  .left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;}
  .left_fixed ul li{background:#000;cursor:pointer;width:15px;height: 15px;border-radius:15px;margin-bottom: 10px;}
  .left_fixed ul li.active{background:#fff;}
</style>

jquery code is as follows (index.js):

var i=0;//翻屏变量，初始第一屏
var s = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象

$(function(){

  var starttime = 0,
    endtime = 0;
  $("body").mousewheel(function(event, delta) {

    starttime = new Date().getTime(); //记录翻屏的初始时间

    if (delta < 0&& i>=0 && i<=2) { 

      if (s>=0&&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏
        s=1;
        i++;
        renderPage(i,true); //翻屏函数
        endtime = new Date().getTime(); //记录翻屏的结束时间
      }
    } else if (delta > 0&& i>=1&&s==1&& (starttime == 0 || (endtime - starttime) <= -500)) {  
      i--;
      //console.log(i);
      renderPage(i,true);
      endtime = new Date().getTime();

  var div_height=$(window).height(); 

  $(".div_01,.div_02,.div_03,.div_04").css({'height':div_height});

        $(".left_fixed ul li").removeClass("active");
        $(".left_fixed ul li").eq(pageNumber).addClass("active");
      }

     return;
    }
