Question

<script language='javascript'>
linkarr = new Array();
picarr = new Array();
textarr = new Array();
var swf_width=280;
var swf_height=192;
var files = "";
var links = "";
var texts = "";
//这里设置调用标记
{dede:arclist flag='f' row='5'}
linkarr[[field:global.autoindex/]] = "[field:arcurl/]";
picarr[[field:global.autoindex/]]  = "[field:litpic/]";
textarr[[field:global.autoindex/]] = "[field:title function='html2text(@me)'/]";
{/dede:arclist}
for(i=1;i<picarr.length;i++){
  if(files=="") files = picarr[i];
  else files += "|"+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 classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="'+ swf_width +'" height="'+ swf_height +'">');
document.write('<param name="movie" value="{dede:global.cfg_templeturl/}/images/bcastr3.swf"><param name="quality" value="high">');
document.write('<param name="menu" value="false"><param name=wmode value="opaque">');
document.write('<param name="FlashVars" value="bcastr_file='+files+'&bcastr_link='+links+'&bcastr_title='+texts+'">');
document.write('<embed src="{dede:global.cfg_templeturl/}/images/bcastr3.swf" wmode="opaque" FlashVars="bcastr_file='+files+'&bcastr_link='+links+'&bcastr_title='+texts+'& menu="false" quality="high" width="'+ swf_width +'" height="'+ swf_height +'" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />'); document.write('</object>');

用javascript模拟实现flash动画切换图片的效果。如果用dedecms，这部分代码需要关注的是它标签的调用{dede:arclist flag='f' row='5'} 
linkarr[[field:global.autoindex/]] = "[field:arcurl/]"; 
picarr[[field:global.autoindex/]]  = "[field:litpic/]"; 
textarr[[field:global.autoindex/]] = "[field:title function='html2text(@me)'/]"; 
{/dede:arclist}
