用Cookie实现仅弹出一次窗口9D4O j@ D W4LY%T
脚本说明:
第一步:把如下代码加入<head>区域中
<SCRIPT language="JavaScript"> (G)n!s8sP!O
<!-- x T&y)D(a
function openpopup(){ o5JxE\O [%X%r
window.open("welcome.htm","","width=300,height=300") {y4X k^ ]0Xq
} ,S}*GLI
function get_cookie(Name) {
var search = Name + "="
var returnvalue = ""; Z y2D l z+TI,p2D-S`
if (document.cookie.length > 0) { OKS#m2HTn r(?8T!e D
offset = document.cookie.indexOf(search) +Z jE O(cq
if (offset != -1) { // if cookie exists /t9i tVg
offset += search.length (MbF0nx X Wj
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value :o~ F9x r_T
if (end == -1)
end = document.cookie.length; g%B1[ I y0f
returnvalue=unescape(document.cookie.substring(offset, end))
} v!zC']q cvc
}
return returnvalue; E8h [E;o/p
}
j| Y y$w#J
function loadpopup(){
if (get_cookie('popped')=='){
openpopup()
document.cookie="popped=yes" ?jUHat b)V5W
} +|W`-]ETNF
}
//-->
</SCRIPT> a Z(r c+j6Q#R h
