本文实例讲述了原生javascript实现的全屏滚动功能。分享给大家供大家参考,具体如下:
原理:
1. 计算当前浏览器屏幕高度,每次翻页显示的内容高度即为屏幕高度
2. 对鼠标滚轮事件进行监听,注意滚轮事件的浏览器兼容问题。
废话不多说,直接上代码
html代码:
<div id="wrap"> <div id="main" style="top: 0;"> <div class="content num1"> <img src="https://www.bing.com/az/hprichbg/rb/SingingRingingTree_ZH-CN12497946624_1920x1080.jpg" width="100%" height="100%"> </div> <div class="content num2"> <img src="https://www.bing.com/az/hprichbg/rb/ShenandoahNP_ZH-CN9981989975_1920x1080.jpg" width="100%" height="100%"> </div> <div class="content num3"> <img src="https://www.bing.com/az/hprichbg/rb/GareSaintLazare_ZH-CN6611772290_1920x1080.jpg" width="100%" height="100%"> </div> <div class="content num4"> <img src="https://www.bing.com/az/hprichbg/rb/FriendshipSquare_ZH-CN8820626148_1920x1080.jpg" width="100%" height="100%"> </div> </div> </div>
css代码:
#wrap{overflow: hidden;width: 100%;} #main{top: 0;position: relative;} .content{width: 100%;margin: 0;height: 100%;} .num1{background: #e8e8e8;} .num2{background: pink;} .num3{background: yellow;} .num4{background: orange;}
js代码:
<script type="text/javascript"> var wrap = document.getElementById("wrap"); var divHeight = window.innerHeight; wrap.style.height = divHeight + "px"; var content = $(".content");//懒得写获取类的原生js代码了,直接用了jquery,=。= content.height(divHeight); 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); } else if (document.addEventListener) { document.addEventListener("mousewheel",scrollFun,false); } else if (document.attachEvent) { 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) > -divHeight * ( content.length - 1)) { //向下翻页 now += divHeight ; turnPage(now); } if (delta < 0 && parseInt(main.style.top) < 0) { //向上翻页 now -= divHeight ; turnPage(now); } endTime = new Date().getTime(); } else{ event.preventDefault(); } } //翻页函数 function turnPage(now){ $("#main").animate({top:(-now+'px')},1000); //懒得写动画代码了,直接用了jquery,=。= } </script>
希望本文所述对大家JavaScript程序设计有所帮助。
