//Customize Dynamic Audio Link 自定义动态声音链接
function DynamicAudioLink(){
open("http://localhost"
}
//Customize Dynamic Audio Mouse Over Color 自定义动态声音mouseover颜色

}

}
do***ent.write('<bgsound id="sound">')
//Customize Button Style 自定义按钮样式
do***ent.write('<style type="text/css">'+'<!--')
do***ent.write('.select{background:#666666;border-color:"#999999";color:"#ffffff";font-family:Arial,Helvetica,Verdana;font-size:10pt;font-weight: bold;}'+'-->'+'</STYLE>')
do***ent.write('<center><form name=Audio><table><tr>')
do***ent.write('<td><input class="select" name=button type="button" value="Dynamic Audio" onclick="DynamicAudioLink()" onMouseOver="AudioOver();playHome()" onMouseDown="AudioDown()" onMouseOut="AudioOut()"></td>')
//下面几行是我加入的代码
do***ent.write('<td><input class="select" name=button type="button" value="Dynamic Audio" onclick="DynamicAudioLink()" onMouseOver="AudioOver();playHome()" onMouseDown="AudioDown()" onMouseOut="AudioOut()"></td>')
//上面几行是我加入的代码
do***ent.write('</tr></table></form></center>')
