wintekweb infoplus: Elapse time, cookies name and last visited, page load time Java Scripts

Elapse time, cookies name and last visited, page load time Java Scripts

Following piece of java Scripts code will show you cookie name and the date of last visited the site.

<!DOCTYPE html>
<html>
<head>
<script>
function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
    {
    return unescape(y);
    }
}
}

function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}

function checkCookie()
{
var username=getCookie("username");
if (username!=null && username!="")
{
alert("Welcome again " + username);
}
else
{
username=prompt("Please enter your name:","");
if (username!=null && username!="")
    {
    setCookie("username",username,365);
    }
}
}
</script>
<script type = "text/javascript">

var days = 730;
var lastvisit=new Object();
var firstvisitmsg="This is your first visit to this page. Welcome!";
lastvisit.subsequentvisitmsg="Welcome back visitor! Your last visit was on <b>[displaydate]</b>";

lastvisit.getCookie=function(Name){
var re=new RegExp(Name+"=[^;]+", "i");
if (document.cookie.match(re))
return document.cookie.match(re)[0].split("=")[1];
return'';
}

lastvisit.setCookie=function(name, value, days){
var expireDate = new Date();

var expstring=expireDate.setDate(expireDate.getDate()+parseInt(days));
document.cookie = name+"="+value+"; expires="+expireDate.toGMTString()+"; path=/";
}

lastvisit.showmessage = function() {
var wh = new Date();
if (lastvisit.getCookie("visitc") == "") {
lastvisit.setCookie("visitc", wh, days);
document.write(firstvisitmsg);
}

else {
var lv = lastvisit.getCookie("visitc");
var lvp = Date.parse(lv);
var now = new Date();
now.setTime(lvp);
var day = new Array("Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat");
var month = new Array ("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec");
var dd = now.getDate();
var dy = now.getDay();
dy = day[dy];
var mn = now.getMonth();
mn = month[mn];
yy = now.getFullYear();
var hh = now.getHours();
var ampm = "AM";
if (hh >= 12) {ampm = "PM"}
if (hh >12){hh = hh - 12};
if (hh == 0) {hh = 12}
if (hh < 10) {hh = "0" + hh};
var mins = now.getMinutes();
if (mins < 10) {mins = "0"+ mins}
var secs = now.getSeconds();
if (secs < 10) {secs = "0" + secs}
var dispDate = dy + ", " + mn + " " + dd + ", " + yy + " " + hh + ":" + mins + ":" + secs + " " + ampm
document.write(lastvisit.subsequentvisitmsg.replace("\[displaydate\]", dispDate))
}

lastvisit.setCookie("visitc", wh, days);

}

lastvisit.showmessage();

</script>
</head>
<body onload="checkCookie()">
</body>
</html>

Bellow codes of Java Scripts shows you elapse time stayed in a specific page as countdown timer

<html>
<head>
<title>load</title>

<Script Language="JavaScript">

var startDate = new Date();
var startTime = startDate.getTime();

function seconds_elapsed ()
{
var date_now = new Date ();
var time_now = date_now.getTime ();
var time_diff = time_now - startTime;
var seconds_elapsed = Math.floor ( time_diff / 1000 );

return ( seconds_elapsed );
}

function time_spent ()
{

var secs = seconds_elapsed ();

var mins = Math.floor ( secs / 60 );
secs -= mins * 60;

var hour = Math.floor ( mins / 60 );
mins -= hour * 60;

document.display.timeElapsed.value = pad ( hour ) + ":" + pad ( mins ) + ":" + pad ( secs );

setTimeout( "time_spent ()", 1000 );
}

function pad ( num )
{
return ( ( num > 9 ) ? num : "0" + num );
}
</Script>
</head>

<body onLoad="time_spent()">

<form name="display">
<input name="timeElapsed" type="text" size=8>
</form>

</body>
</html>

Following codes are really php in which you can find the tame taken to page load.
