2、ys = 30; var exp = new Date(); exp.setTime(exp.getTime() + (expDays*24*60*60*1000); function Who(info) var VisitorName = GetCookie(VisitorName) if (VisitorName = null) VisitorName = prompt(您的尊姓大名：); SetCookie (VisitorName, VisitorName, exp); return VisitorName; function When(info) var rightNow = new

3、 Date() var WWHTime = 0; WWHTime = GetCookie(WWhenH) WWHTime = WWHTime * 1 var lastHereFormatting = new Date(WWHTime); var intLastVisit = (lastHereFormatting.getYear() * 10000)+(lastHereFormatting.getMonth() * 100) + lastHereFormatting.getDate() var lastHereInDateFormat = + lastHereFormatting; var d

4、ayOfWeek = lastHereInDateFormat.substring(0,3) var dateMonth = lastHereInDateFormat.substring(4,11) var timeOfDay = lastHereInDateFormat.substring(11,16) var year = lastHereInDateFormat.substring(23,25) var WWHText = dayOfWeek + , + dateMonth + at + timeOfDay SetCookie (WWhenH, rightNow.getTime(), e

7、= document.cookie.length; var i = 0; while (i clen) var j = i + alen; if (document.cookie.substring(i, j) = arg) return getCookieVal (j); i = document.cookie.indexOf( , i) + 1; if (i = 0) break; return null; function SetCookie (name, value) var argv = SetCookie.arguments; var argc = SetCookie.argume

8、nts.length; var expires = (argc 2) ? argv2 : null; var path = (argc 3) ? argv3 : null; var domain = (argc 4) ? argv4 : null; var secure = (argc 5) ? argv5 : false; document.cookie = name + = + escape (value) + (expires = null) ? : (; expires= + expires.toGMTString() + (path = null) ? : (; path= + pa
