在document.write('</object>');之前加以下一句就能在FF下显示了：
document.write('<embed src="/templates/default/images/focus2.swf" FlashVars="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'" quality="high" allowScriptAccess="sameDomain" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="355" height="230"></embed>');
