基本思路：
1）檢測(cè)手指滑動(dòng)方向：獲取手指抬起時(shí)的位置，減去手指按下時(shí)的位置，得正即為向下滑動(dòng)了
2）手指抬起后，向?qū)?yīng)反向操作改變當(dāng)前頁(yè)的位置
具體代碼如下：
html
<div id="wrap"> <div id="page01" class="pages">第一屏</div> <div id="page02" class="pages">第二屏</div> <div id="page03" class="pages">第三屏</div> <div id="page04" class="pages">第四屏</div></div><div id="dots"> <span class="now"></span><span class=""></span><span class=""></span><span class=""></span></div>
css
*{ margin:0; padding:0; } body{ overflow: hidden; } #wrap > div{ width: 10rem; position: absolute; left: 0; top: 0; background: #fff; transition: all 0.3s ease; } #dots{ position: fixed; right: 5px; top: 40%; z-index: 9; } #dots span{ display: block; height: 0.2rem; width: 0.2rem; border: 1px solid #000; border-radius: 50%; margin-bottom: 3px; } #dots .now{ background: #555; }js分為兩塊
第一，設(shè)置html標(biāo)簽的font-size，以便設(shè)置rem的基數(shù) （放在頁(yè)面頭部）
document.getElementsByTagName("html")[0].style.fontSize = window.innerWidth/10 + "px";第二，具體的滑動(dòng)操作代碼
window.onload = function(){ var oDiv = document.getElementById("wrap"); var aPages = oDiv.getElementsByClassName("pages"); var aDots = document.getElementById("dots").getElementsByTagName("span"); var winH = window.innerHeight; var tTime = 1; //設(shè)置每頁(yè)的高度和zindex值 for(var i=0; i<aPages.length; i++){ aPages[i].style.height = winH + "px"; aPages[i].style.zIndex = 1; } aPages[0].style.zIndex = 3; aPages[1].style.zIndex = 2; oDiv.style.height = winH + "px"; //手指拖動(dòng)事件（去除默認(rèn)動(dòng)作） document.addEventListener("touchmove",function(e){ e.preventDefault(); }); var YStart = 0; var iNow = 0; //手指按下 oDiv.addEventListener("touchstart",function(e){ YStart = e.changedTouches[0].clientY; }); //手指移動(dòng) oDiv.addEventListener("touchmove",function(e){ disY = e.changedTouches[0].clientY-YStart; //向下滑正，向上滑負(fù) }); //手指離開(kāi) oDiv.addEventListener("touchend",function(e){ disY = e.changedTouches[0].clientY-YStart; //向下滑正，向上滑負(fù) if(Math.abs(disY)>winH/20){ //只有當(dāng)滑動(dòng)距離大于了一定值得時(shí)候，才執(zhí)行切換 if(disY<0){ iNow++; if(iNow>=aDots.length){ iNow = 0; } aPages[0].style.transform = "translateY("+ -winH +"px)"; doSlide(); }else{ iNow--; if(iNow<0){ iNow = aDots.length-1; } aPages[0].style.transform = "translateY("+ winH +"px)"; doSlide("up"); } } }); function doSlide(upflag){ for(var i=0;i<aDots.length;i++){ aDots[i].className = ""; } aDots[iNow].className = "now"; if(upflag){ //向上滑 aPages[3].style.zIndex = 2; aPages[1].style.zIndex = 1; oDiv.insertBefore(aPages[3],aPages[1]); setTimeout(function(){ aPages[1].style.transform = "translateY(0px)"; aPages[1].style.zIndex = 2; aPages[0].style.zIndex = 3; },300) }else{ setTimeout(function(){ aPages[0].style.transform = "translateY(0px)"; aPages[0].style.zIndex = 1; aPages[1].style.zIndex = 3; aPages[2].style.zIndex = 2; oDiv.appendChild(aPages[0]); },300) } } }好了，在給大家分享一段簡(jiǎn)單的代碼，JS實(shí)現(xiàn)移動(dòng)端整頁(yè)滑屏示，具體代碼如下所示：
