第一步:把如下代码加入<head>区域中
<SCRIPT language="JavaScript">
<!--
function openpopup(){
window.open("welcome.htm","","width=300,height=300")
}
function get_cookie(Name){
var search=Name + "="
var returnvalue = "";
if(document.cookie.length > 0){
offset=document.cookie.indexOf(search)
if(offset!= -1){// if cookie exists
offset +=search.length
//set index of beginning of value
end = document.cookie.indexOf(";",offset);
//set index of end of cookie value
if(end == -1)
end=document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset,end))
}
}
return returnvalue;
}
function loadpopup
if(get_cookie('popped')==''){
openpopup()
document.cookie="popped=yes"
}
}
//-->
</SCRIPT>
第二步:把<body>中内容改为:
<body bgcolor="#fef4d9" onunload="loadpopup()>
