H5实现仿flash效果的实现代码

随着H5的火热，flash即将被H5所代替，如何利用H5实现flash的效果呢？我做了一个简单的小东西分享给大家。

html和js部分：

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title> <script type="text/javascript" src="jsByKing.js"></script> <link rel="stylesheet" href="仿flash的css.css" rel="external nofollow" > <script> function getByClass(oParent,sClass) { var aEle=oParent.getElementsByTagName('*'); var aResult=[]; for(var i=0;i<aEle.length;i++){ if(aEle[i].className==sClass){ aResult.push(aEle[i]); } } return aResult; } //左右箭头 window.onload=function () { var oDiv=document.getElementById('playimages'); var oBtnPrev=getByClass(oDiv,'prev')[0]; var oBtnNext=getByClass(oDiv,'next')[0]; var oMarkLeft=getByClass(oDiv,'mark_left')[0]; var oMarkRight=getByClass(oDiv,'mark_right')[0]; var oDivSmall=getByClass(oDiv,'small_pic')[0]; var oUlSmall=oDivSmall.getElementsByTagName('ul')[0]; var aLiSmall=oDivSmall.getElementsByTagName('li'); var oUlBig=getByClass(oDiv,'big_pic')[0]; var aLiBig=oUlBig.getElementsByTagName('li'); var nowZIndex=2; var now=0; oUlSmall.style.width=aLiSmall.length*aLiSmall[0].offsetWidth+'px'; oBtnPrev.onmouseover=oMarkLeft.onmouseover=function () { startMove(oBtnPrev,'opacity',100); }; oBtnPrev.onmouseout=oMarkLeft.onmouseout=function () { startMove(oBtnPrev,'opacity',0); } oBtnNext.onmouseover=oMarkRight.onmouseover=function () { startMove(oBtnNext,'opacity',100); }; oBtnNext.onmouseout=oMarkRight.onmouseout=function () { startMove(oBtnNext,'opacity',0); } //大图切换 for(var i=0; i<aLiSmall.length;i++){ aLiSmall[i].index=i; aLiSmall[i].onclick=function () { if(this.index==now)return; now=this.index; tab(); aLiSmall[i].onmouseover=function () { startMove(this,'opacity',100); } aLiSmall[i].onmouseout=function () { if(this.index!=now){ startMove(this,'opacity',60) } } } function tab() { aLiBig[now].style.zIndex=nowZIndex++; for(var i=0;i<aLiSmall.length;i++){ startMove(aLiSmall[i],'opacity',60); } startMove(aLiSmall[now],'opacity',100); aLiBig[now].style.height=0; startMove(aLiBig[now],'height',320); if(now==0){ startMove(oUlSmall,'left',0); } else if(now==aLiSmall.length-1){ startMove(oUlSmall,'left',-(now-2)*aLiSmall[0].offsetWidth); } else { startMove(oUlSmall,'left', -(now-1)*aLiSmall[0].offsetWidth); } }; } oBtnPrev.onclick=function () { now--; if(now==-1){ now=aLiSmall.length-1; } tab(); }; oBtnNext.onclick=function () { now++; if(now==aLiSmall.length){ now=0; } tab(); } var timer=setInterval(oBtnNext.onclick,2000); oDiv.onmouseover=function () { clearInterval(timer); } oDiv.onmouseout=function () { timer=setInterval(oBtnNext.onclick,2000); } } </script></head><body><div id="playimages" class="play"> <ul class="big_pic"> <div class="prev"></div> <div class="next"></div> <div class="text">加载图片说明.....</div> <div class="length">计算图片数量.....</div> <a class="mark_left" href="javascript:;" rel="external nofollow" rel="external nofollow" ></a> <a class="mark_right" href="javascript:;" rel="external nofollow" rel="external nofollow" ></a> <div class="bg"></div> <li style="z-index: 1;"><img src="../../img/练习/1.jpg" alt=""></li> <li><img src="../../img/练习/2.jpg" alt=""></li> <li><img src="../../img/练习/3.jpg" alt=""></li> <li><img src="../../img/练习/4.jpg" alt=""></li> <li><img src="../../img/练习/5.jpg" alt=""></li> <li><img src="../../img/练习/6.jpg" alt=""></li> </ul> <div class="small_pic"> <ul style="width: 390px;"> <li style="opacity: 1"><img src="../../img/练习/1.jpg" alt=""></li> <li><img src="../../img/练习/2.jpg" alt=""></li> <li><img src="../../img/练习/3.jpg" alt=""></li> <li><img src="../../img/练习/4.jpg" alt=""></li> <li><img src="../../img/练习/5.jpg" alt=""></li> <li><img src="../../img/练习/6.jpg" alt=""></li> </ul> </div></div></body></html>

css部分：

body{ background: #666;}ul{ padding: 0; margin: 0;}li{ list-style: none;}img{ border:0; width: 100%; height: 100%;}.play{ width: 400px; height: 430px; margin: 50px auto 0; background: #999; font: 12px Arial;}.big_pic{ width: 400px; height: 320px; overflow: hidden; border-bottom: 1px solid #ccc; background: #222; position: relative;}.big_pic img{ width: 400px; height: 320px;}.big_pic li{ width: 400px; height: 320px; overflow: hidden; position: absolute; top:0; left:0; z-index: 0;}.mark_left{ width: 200px; height: 320px; position: absolute; left: 0; top:0; opacity: 0; z-index: 3000; }.mark_right{ width: 200px; height: 320px; position: absolute; left: 200px; top:0; opacity: 0; z-index: 3000;}.big_pic .prev{ width: 60px; height: 60px; background-image: url("../../img/练习/left.jpg"); background-size: cover; position: absolute; top: 130px; left: 10px; z-index: 3001; opacity: 0; cursor: pointer;}.big_pic .next{ width: 60px; height: 60px; background-image: url("../../img/练习/right.jpg"); background-size: cover; background-position: 65px 60px; position: absolute; top: 130px; right: 10px; z-index: 3001; opacity: 0; cursor: pointer;}.big_pic .text{ position: absolute; left: 10px; bottom: 4px; z-index: 3000; color: #ccc;}.big_pic .length{ position: absolute; right: 10px; bottom: 4px; z-index: 3000; color: #ccc;}.big_pic .bg{ width: 400px; height: 25px; background: #000; opacity: 0.6; position: absolute; z-index: 2999; bottom: 0; left:0;}.small_pic{ width: 380px; height: 94px; position: relative; top: 7px; left: 10px; overflow: hidden;}.small_pic ul{ height: 94px; position: absolute; top:0; left: 0;}.small_pic li{ width: 120px; height: 94px; float: left; padding-right: 10px; cursor: pointer; opacity: 0.6;}
