本文實(shí)例講述了原生javascript實(shí)現(xiàn)的全屏滾動(dòng)功能。分享給大家供大家參考，具體如下：
原理：
1. 計(jì)算當(dāng)前瀏覽器屏幕高度，每次翻頁(yè)顯示的內(nèi)容高度即為屏幕高度
2. 對(duì)鼠標(biāo)滾輪事件進(jìn)行監(jiān)聽(tīng)，注意滾輪事件的瀏覽器兼容問(wèn)題。
廢話不多說(shuō)，直接上代碼
html代碼：
<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代碼：
#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代碼：
<script type="text/javascript"> var wrap = document.getElementById("wrap"); var divHeight = window.innerHeight; wrap.style.height = divHeight + "px"; var content = $(".content");//懶得寫獲取類的原生js代碼了，直接用了jquery，=。= content.height(divHeight); var startTime = 0, //開(kāi)始翻屏?xí)r間 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; } //滾動(dòng)事件處理函數(shù) function scrollFun(event){ startTime = new Date().getTime(); var delta = event.detail || (-event.wheelDelta); if ((endTime - startTime) < -1000) { //1秒內(nèi)執(zhí)行一次翻頁(yè) if (delta > 0 && parseInt(main.style.top) > -divHeight * ( content.length - 1)) { //向下翻頁(yè) now += divHeight ; turnPage(now); } if (delta < 0 && parseInt(main.style.top) < 0) { //向上翻頁(yè) now -= divHeight ; turnPage(now); } endTime = new Date().getTime(); } else{ event.preventDefault(); } } //翻頁(yè)函數(shù) function turnPage(now){ $("#main").animate({top:(-now+'px')},1000); //懶得寫動(dòng)畫代碼了，直接用了jquery，=。= }</script>希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
