代碼二：

代碼如下：

<script type=

"text/javascript"

var

caution=

false

function

setCookie(name,value,expires,path,domain,secure)

var

curCookie=name+

"="

+escape(value) +

((expires)?

";expires="

+expires.toGMTString() :

""

) +

((path)?

"; path="

+ path :

""

) +

((domain)?

"; domain="

+ domain :

""

) +

((secure)?

";secure"

""

if

(!caution||(name +

"="

+ escape(value)).length <= 4000)

document.cookie = curCookie

else

if

(confirm(

"Cookie exceeds 4KB and will be cut!"

))

document.cookie = curCookie

function

getCookie(name)

var

prefix = name +

"="

var

cookieStartIndex = document.cookie.indexOf(prefix)

if

(cookieStartIndex == -1)

return

null

var

cookieEndIndex=document.cookie.indexOf(

";"

,cookieStartIndex+prefix.length)

if

(cookieEndIndex == -1)

cookieEndIndex = document.cookie.length

return

unescape(document.cookie.substring(cookieStartIndex+prefix.length,cookieEndIndex))

function

if

(getCookie(name))

document.cookie = name +

"="

((path) ?
