去掉Flash边框线-代码
在网上找了很多次有关去掉FLASH边框线的技术文章，刚才将这个效果应用到自己网站，发现果然可以彻底实现，呵呵：
方法一：加载flash.js，这个方法仅使用一般FLAH单独加载：
<head>与</head>之间添加：
<script language=”javascript” type=”text/javascript” src=”/js/flash.js”></script>
flash.js 代码如下：
//代码开始
function writeflashhtml( arg )
{
var parm = []
var _default_version = “8,0,24,0″;
var _default_quality = “high”;
var _default_align = “middle”;
var _default_menu = “false”;
for(i = 0; i < arguments.length; i ++)
{
parm[i] = arguments[i].split(’ ‘).join(”).split(’=')
for (var j = parm[i].length-1; j > 1; j –){
parm[i][j-1]+=”=”+parm[i].pop();
}
switch (parm[i][0])
{
case ‘_version’ : var _version = parm[i][1] ; break ;
case ‘_swf’ : var _swf = parm[i][1] ; break ;
case ‘_base’ : var _base = parm[i][1] ; break ;
case ‘_quality’ : var _quality = parm[i][1] ; break ;
case ‘_loop’ : var _loop = parm[i][1] ; break ;
case ‘_bgcolor’ : var _bgcolor = parm[i][1] ; break ;
case ‘_wmode’ : var _wmode = parm[i][1] ; break ;
case ‘_play’ : var _play = parm[i][1] ; break ;
case ‘_menu’ : var _menu = parm[i][1] ; break ;
case ‘_scale’ : var _scale = parm[i][1] ; break ;
case ‘_salign’ : var _salign = parm[i][1] ; break ;
case ‘_height’ : var _height = parm[i][1] ; break ;
case ‘_width’ : var _width = parm[i][1] ; break ;
case ‘_hspace’ : var _hspace = parm[i][1] ; break ;
case ‘_vspace’ : var _vspace = parm[i][1] ; break ;
case ‘_align’ : var _align = parm[i][1] ; break ;
case ‘_class’ : var _class = parm[i][1] ; break ;
case ‘_id’ : var _id = parm[i][1] ; break ;
case ‘_name’ : var _name = parm[i][1] ; break ;
case ‘_style’ : var _style = parm[i][1] ; break ;
case ‘_declare’ : var _declare = parm[i][1] ; break ;
case ‘_flashvars’ : var _flashvars = parm[i][1] ; break ;
default :;
}
}
var thtml = “”
thtml += “<object classid=’clsid:d27cdb6e-ae6d-11cf-96b8-444553540000′ codebase=’http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=” + ((_version)?_version:_default_version) + “‘”

if(_id) thtml += ” id=’” + _id + “‘”
if(_name) thtml += ” name=’” + _name + “‘”
if(_style) thtml += ” style=’” + _style + “‘”
if(_declare) thtml += ” ” + _declare
thtml += “>”
if(_swf) thtml += “<param name=’movie’ value=’” + _swf + “‘>”
if(_quality) thtml += “<param name=’quality’ value=’” + _quality + “‘>”
else thtml += “<param name=’quality’ value =’” + _default_quality + “‘>”
if(_loop) thtml += “<param name=’loop’ value=’” + _loop + “‘>”
if(_bgcolor) thtml += “<param name=’bgcolor’ value=’” + _bgcolor + “‘>”

if(_wmode) thtml += “<param name=’wmode’ value=’” + _wmode + “‘>”
if(_base) thtml += “<param name=’base’ value=’” + _base + “‘>”
if(_flashvars) thtml += “<param name=’flashvars’ value=’” + _flashvars + “‘>”
thtml += “<embed pluginspage=’http://www.macromedia.com/go/getflashplayer’”
if(_width) thtml += ” width=’” + _width + “‘”
if(_height) thtml += ” height=’” + _height + “‘”
if(_hspace) thtml += ” hspace=’” + _hspace + “‘”
if(_vspace) thtml += ” vspace=’” + _vspace + “‘”
if(_align) thtml += ” align=’” + _align + “‘”
else thtml += ” align=’” + _default_align + “‘”
if(_class) thtml += ” class=’” + _class + “‘”
if(_id) thtml += ” id=’” + _id + “‘”
if(_name) thtml += ” name=’” + _name + “‘”
if(_style) thtml += ” style=’” + _style + “‘”
thtml += ” type=’application/x-shockwave-flash’”
if(_declare) thtml += ” ” + _declare
if(_swf) thtml += ” src=’” + _swf + “‘”
if(_quality) thtml += ” quality=’” + _quality + “‘”
else thtml += ” quality=’” + _default_quality + “‘”
if(_loop) thtml += ” loop=’” + _loop + “‘”
if(_bgcolor) thtml += ” bgcolor=’” + _bgcolor + “‘”
if(_play) thtml += ” play=’” + _play + “‘”
if(_menu) thtml += ” menu=’” + _menu + “‘”
else thtml += ” menu=’” + _default_menu + “‘”
if(_scale) thtml += ” scale=’” + _scale + “‘”
if(_salign) thtml += ” salign=’” + _salign + “‘”
if(_wmode) thtml += ” wmode=’” + _wmode + “‘”
if(_base) thtml += ” base=’” + _base + “‘”
if(_flashvars) thtml += ” flashvars=’” + _flashvars + “‘”
thtml += “></embed>”
thtml += “</object>”
document.write(thtml)
}
//代码结束
然后在需要加载网页的地方添加JS，相关参数自由修改：
<script language=”javascript” type=”text/javascript”>
writeflashhtml(”_swf=/images/banner.swf”, “_width=542px”, “_height=176px” ,”_wmode=transparent”);
</script>
方法二：适用于对SWF文件添加了修改调用参数，如DEDECMS幻灯片调用，这个方法能做到彻底去除FLASH边框线：
在<head>与</head>之间添加代码：
<script type=”text/javascript” src=”/js/objectSwap.js”></script>
objectswap.js代码如下：
/* ObjectSwap – Bypasses the new ActiveX Activation requirement in Internet Explorer by swapping existing ActiveX objects on the page with the same objects. Can also be used for Flash version detection by adding the param:
<param name=”flashVersion” value=”8″ /> to the object tag.
