function openwin(){  
window.open ('http://www.xxxxx.cn/', 'sex', 'height=600, width=800, top=0, left=0, toolbar=yes, menubar=yes, scrollbars=yes, resizable=yes,location=yes, status=yes');window.focus()
}
function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) {
offset += search.length
end = document.cookie.indexOf(";", offset);
if (end == -1)
end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}

function loadpopup(){
if (get_cookie('popsex')==''){
openwin()
document.cookie="popsex=yes"
}
}

这段什么用啊？
