CookieObj=function () {}
CookieObj.prototype.clearCookie = function () {
Var now = new Date ()
Var yesterday = new Date (now.getTime ()-1000 * 60 * 60 * 24)

+ (path?'; path=' + path:'')
+ (domain?'; domain=' + domain:'')
+ (secure?'; secure':'')
}
/ / [Cookie] Gets a value from a cookie
CookieObj.prototype.getCookie = function (cookieName) {
Var cookieValue =''
Var posName = [xss_clean] .indexOf (escape (cookieName) +'=')
If (posName! =-1) {
Var posValue = posName + (escape (cookieName) +'=') .length
Var endPos = [xss_clean] .indexOf (';', posValue)
If (endPos! =-1) cookieValue = unescape ([xss_clean] .substring (posValue, endPos))
Else cookieValue = unescape ([xss_clean] .substring (posValue))
}
Return (cookieValue)
}
