H5實現仿flash效果的實現代碼
隨著H5的火熱，flash即將被H5所代替，如何利用H5實現flash的效果呢？我做了一個簡單的小東西分享給大家。
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;
}
//左右箭頭
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);

//大圖切換
for(var i=0; i<aLiSmall.length;i++){

aLiSmall[i].onclick=function () {
if(this.index==now)return;
now=this.index;

startMove(aLiBig[now],'height',320);

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

};
}
