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 () {

      }

      //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++;

        if(now==0){
          startMove(oUlSmall,'left',0);
        }
        else if(now==aLiSmall.length-1){
          startMove(oUlSmall,'left',-(now-2)*aLiSmall[0].offsetWidth);
        }

        else {

      }
