javascript+html5实现仿flash滚动播放图片的方法_javascript技巧

本文实例讲述了javascript+html5实现仿flash滚动播放图片的方法。分享给大家供大家参考。具体如下：

html部分：

css部分：

body{ margin: 0px; padding: 0px; }
ul{ margin: 0px; padding: 0px; }
li{ list-style: none; } 
.play{ width: 600px; height: 550px; left: 30px; top: 20px;
position: relative; border: 2px solid black;
} 
.big_pic{ width: 600px; height: 400px; position: relative;
background: snow; overflow: hidden;
} 
.big_pic li{ width: 600px; height: 400px; overflow:hidden;
position: absolute; background: black; z-index: 0
} 
.big_pic li img{ width: 600px; height: 400px;
position: absolute;
} 
.mark_left{ width: 300px; height: 400px;
background: orange; position: absolute; left: 0px; top: 0px;
z-index: 3000; filter: alpha(opacity:0); opacity: 0;
} 
.mark_right{ width: 300px; height: 400px; background: cornflowerblue;
position: absolute; left: 300px; top: 0px;
z-index: 3000; filter: alpha(opacity:0); opacity: 0;
} 
.prev{ width: 60px; height: 60px; 
background: url(image/btn.gif) no-repeat; position: absolute; 
z-index: 3001; top: 170px; left: 10px; cursor: pointer; 
filter: alpha(opacity:0); opacity: 0;
} 
.next{ width: 60px; height: 60px; 
background: url(image/btn.gif) no-repeat 0 -60px; 
position: absolute; z-index: 3001; top: 170px; right: 10px;
cursor: pointer; filter: alpha(opacity:0); opacity: 0;
} 
.small_pic{ width: 594px; height: 144px; 
position: relative;top: 0;left: 0;
border: 3px solid paleturquoise;overflow: hidden;
} 
.small_pic ul{ width: 594px; height: 144px; 
position: absolute; left: 0px;top: 0px;
} 
.small_pic li img{ width: 194px; height: 140px; } 
.small_pic ul li{ border:2px solid paleturquoise;
width: 194px; height: 140px; float: left;
cursor: pointer; filter: alpha(opacity:60); opacity: 0.6;
}

JS部分：

window.onload=function(){ 
 var oPlay=document.getElementById('playImages'); 
 var uBig=getClass(oPlay,'big_pic')[0]; 
 var uSmall=getClass(oPlay,'small_pic')[0]; 
 var oPrev=getClass(oPlay,'prev')[0]; 
 var oNext=getClass(oPlay,'next')[0]; 
 var aLeft=getClass(oPlay,'mark_left')[0]; 
 var aRight=getClass(oPlay,'mark_right')[0]; 
 var oUlSmall=uSmall.getElementsByTagName('ul')[0]; 
 var oSli=uSmall.getElementsByTagName('li'); 
 var oBli=uBig.getElementsByTagName('li'); 
 oUlSmall.style.width=oSli[0].offsetWidth*oSli.length+'px'; 
 oPrev.onmouseover=aLeft.onmouseover=function(){ 
  move(oPrev,100,'opacity'); 
 }; 
 oPrev.onmouseout=aLeft.onmouseout=function(){ 
  move(oPrev,0,'opacity'); 
 }; 
 oNext.onmouseover=aRight.onmouseover=function(){ 
  move(oNext,100,'opacity'); 
 }; 
 oNext.onmouseout=aRight.onmouseout=function(){ 
  move(oNext,0,'opacity'); 
 }; 
 var index=0; 
 var newZIndex=2; 
 for (var i=0;i0?Math.ceil(speed):Math.floor(speed); 
  if(cur==iTarget){ 
   clearInterval(obj.timer); 
  }else{ 
   if(name=='opacity'){ 
    obj.style.opacity=(cur+speed)/100; 
    obj.style.filter='alpha(opacity:'+cur+speed+')'; 
   }else{ 
    obj.style[name]=cur+speed+"px"; 
   } 
  } 
 },30); 
}; 
function getClass(oParent,name){ 
 var oArray=[]; 
 var oBj=oParent.getElementsByTagName('*'); 
 for(var i=0;i
