This article mainly introduces the full-screen scrolling function implemented by native javascript, involving implementation techniques related to javascript event response and dynamic operation of page element attributes. Friends in need can refer to it. I hope it can help everyone,

Principle:

1. Calculate the height of the current browser screen, and the height of the content displayed each time you turn the page is the screen height

2. For mouse Monitor the scroll wheel event and pay attention to the browser compatibility issues of the scroll wheel event.

Without further ado, let’s go straight to the code

html code:


<p id="wrap">
  <p id="main" style="top: 0;">
    <p class="content num1">
      <img src="https://www.bing.com/az/hprichbg/rb/SingingRingingTree_ZH-CN12497946624_1920x1080.jpg" width="100%" height="100%">
    </p>
    <p class="content num2">
      <img src="https://www.bing.com/az/hprichbg/rb/ShenandoahNP_ZH-CN9981989975_1920x1080.jpg" width="100%" height="100%">
    </p>
    <p class="content num3">
      <img src="https://www.bing.com/az/hprichbg/rb/GareSaintLazare_ZH-CN6611772290_1920x1080.jpg" width="100%" height="100%">
    </p>
    <p class="content num4">
      <img src="https://www.bing.com/az/hprichbg/rb/FriendshipSquare_ZH-CN8820626148_1920x1080.jpg" width="100%" height="100%">
    </p>

  content.height(pHeight);
  var startTime = 0, //开始翻屏时间
    endTime = 0,
    now = 0;
  if ((navigator.userAgent.toLowerCase().indexOf("firefox")!=-1)){
    //for firefox;
    document.addEventListener("DOMMouseScroll",scrollFun,false);

    document.attachEvent("onmousewheel",scrollFun);
  }
  else{
    document.onmousewheel = scrollFun;
  }
  //滚动事件处理函数
  function scrollFun(event){
      startTime = new Date().getTime();
      var delta = event.detail || (-event.wheelDelta);
      if ((endTime - startTime) < -1000) {
        //1秒内执行一次翻页
        if (delta > 0 && parseInt(main.style.top) > -pHeight * ( content.length - 1)) { //向下翻页
          now += pHeight ;
          turnPage(now);
        }
        if (delta < 0 && parseInt(main.style.top) < 0) { //向上翻页
          now -= pHeight ;
          turnPage(now);

      else{
        event.preventDefault();
      }
  }
  //翻页函数
  function turnPage(now){
    $("#main").animate({top:(-now+&#39;px&#39;)},1000);
    //懒得写动画代码了,直接用了jquery,=。=
