JS实现图片轮换效果

  当前的项目中要用到的效果,网上下了几个"源码",但都不是很如意,只好自己研究了,效果演示地址: http://www.cnbeta.com/ ,首页的左边的那个图片轮播就是我想要的效果, 研究了一下他的源码,发现原来是这么简单呀..一段JS代码搞掂.

    <script language="javascript">
linkarr = new Array();
picarr = new Array();
textarr = new Array();
var focus_width=409;   // 图片的宽度
var focus_height=307;  // 图片的高度
var text_height=20;  // 底部文字的高度
var pics = "";
var links = "";
var texts = "";
var swf_height = focus_height+text_height;   // 整个轮换效果的高度=图片高度+底部文字高度
var defJpeg = "http://www.cnbeta.com/images/index_37.jpg";

linkarr[1]="http://www.cnbeta.com/articles/73700.htm";picarr[1] ="images/1.jpg";textarr[1]="cnBeta 08年度精彩评论";linkarr[2]="http://www.cnbeta.com/articles/73715.htm";picarr[2] ="images/2.jpg";textarr[2]="国务院常务会议同意启动3G牌照发放";linkarr[3]="http://www.cnbeta.com/articles/73734.htm";picarr[3] ="images/3.jpg";textarr[3]="cnBeta 2009 新年献词";linkarr[4]="http://www.cnbeta.com/articles/73473.htm";picarr[4] ="images/4.jpg";textarr[4]="三大XP盗版集团全面撤退 灰色产业链悄然漂白";linkarr[5]="http://www.cnbeta.com/articles/73531.htm";picarr[5] ="images/5.jpg";textarr[5]="儿时经典动画《葫芦兄弟》也要出网游啦";

for(i=1;i<picarr.length;i++){
  //if(picarr[i].indexOf("jpg")==-1 && picarr[i].indexOf("JPG")==-1) picarr[i] = defJpeg;
  if(pics=="") pics = picarr[i];
  else pics += "|"+picarr[i];
}

for(i=1;i<linkarr.length;i++){
  if(links=="") links = linkarr[i];
  else links += "|"+linkarr[i];
}

for(i=1;i<textarr.length;i++){
  if(texts=="") texts = textarr[i];
  else texts += "|"+textarr[i];
}


document.write('<object type="application/x-shockwave-flash" data="template/slide.swf" width="' + focus_width + '" height="' + swf_height + '">');
            document.write('<param name="movie" value="template/slide.swf" />');

            document.write('</object>');

    实现图片轮换效果的其实是一个flash,就是那个template/slide.swf,真想看看他的源码,不知道他是怎么读取传进去的参数的哦!!!
    要注意的时候图片和那个slide.swf必须在同一站点下,要不然就会显示出错了,比如上面的代码改成http://www.cnbeta.com/template/slide.swf后显示就不正常了!!!
