JavaScripti >> Uporaba piškotkov >> Ime-obiskov-zadnji obisk

Opis:
Podatke zapisuje v piškotke (cookies) na računalnik in nato iz njih prebere ime (ki je bilo vpisano), število obiskov in zadnji obisk. Če ne vrjamete pritisnite kdaj tudi na gumb "osveži" (refresh) in videli boste razliko.

Primer:

Izvorna koda:

Korak 1 :
Ta del kode vstavite v <head> del strani:

<SCRIPT LANGUAGE="JavaScript"> var expDays = 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("Kako ti je ime?"); SetCookie ('VisitorName', VisitorName, exp); } return VisitorName; } function When(info){ var rightNow = new 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 dayOfWeek = 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 + " ob " + timeOfDay SetCookie ("WWhenH", rightNow.getTime(), exp) return WWHText } function Count(info){ var WWHCount = GetCookie('WWHCount') if (WWHCount == null) { WWHCount = 0; } else{ WWHCount++; } SetCookie ('WWHCount', WWHCount, exp); return WWHCount; } function set(){ VisitorName = prompt("Kako ti je ime?"); SetCookie ('VisitorName', VisitorName, exp); SetCookie ('WWHCount', 0, exp); SetCookie ('WWhenH', 0, exp); } function getCookieVal (offset) { var endstr = document.cookie.indexOf (";", offset); if (endstr == -1) endstr = document.cookie.length; return unescape(document.cookie.substring(offset, endstr)); } function GetCookie (name) { var arg = name + "="; var alen = arg.length; var clen = 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.arguments.length; var expires = (argc > 2) ? argv[2] : null; var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null; var secure = (argc > 5) ? argv[5] : false; document.cookie = name + "=" + escape (value) + ((expires == null) ?

Korak 2:
Ta del kode vstavite v <body> del strani:

<SCRIPT LANGUAGE="JavaScript"> document.write("Živjo " + Who() + "! Tukaj si bil " + Count() + "-krat. Zadnjič si bil tukaj: " + When() +"."); </SCRIPT>
