php ajax auto logout with timer
<script type="text/javascript">
var t;
function startTimer(){
t=setTimeout("document.location='../login/logout.php'", 50000);
}
function stopTimer(){
clearTimeout(t);
}
</script>
This is my script for auto logout,
i want to show the countdown timer, How to create and show the timer,
Also i want to make alive when the user hit the body of the page,
Also timer should reset and then restart again when system is idle,
How to make it,
(Timer should show , that is , timer should run when people not touching the sy开发者_运维百科stem ,
if user touch the system then counter should restart )
Use this function:
function timer(elem, starttime, endtime, speed, funktion, count) {
if (!endtime) endtime = 0;
if (!starttime) starttime = 10;
if (!speed) speed = 1;
speed = speed * 1000;
if ($(elem).html() || $(elem).val()) {
if (count == "next" && starttime > endtime) starttime--;
else if (count == "next" && starttime < endtime) starttime++;
if ($(elem).html()) $(elem).html(starttime);
else if ($(elem).val()) $(elem).val(starttime);
if (starttime != endtime && $(elem).html()) setTimeout(function() {
timer(elem, $(elem).html(), endtime, speed / 1000, funktion, 'next');
}, speed);
if (starttime != endtime && $(elem).val()) setTimeout(function() {
timer(elem, $(elem).val(), endtime, speed / 1000, funktion, 'next');
}, speed);
if (starttime == endtime && funktion) funktion();
} else return;
}
Example
timer("#timer", 50, 0, 1, function() {
location.href = "../login/logout.php";
});
my example:
Updated to check if the user is Idle (is set to 2 seconds, this makes testing easier, i'd recommend at least 5 or 10 minutes).
<body onload="setTimeout('startCountDown()',2000);" onmousemove="resetTimer();">
<form name="counter"><input type="text" size="5" name="timer" disabled="disabled" /></form>
<script type="text/javascript">
<!--
// edit startSeconds as you see fit
// simple timer example provided by Thomas
var startSeconds = 10;
var milisec = 0;
var seconds=startSeconds;

function CountDown()
{
if(idle == true)

document.counter.timer.value=seconds+"."+milisec;
setTimeout("CountDown()",100);
}
else
{

}
}
function startCountDown()
{
document.counter.timer.value=startSeconds;
seconds = startSeconds;
milisec = 0
document.counter.timer.style.display = 'block';
idle = true;
CountDown();
document.getElementById("alert").innerHTML = 'You are idle. you will be logged out after ' + startSeconds + ' seconds.';
countdownrunning = false;
}
function resetTimer()
{
document.counter.timer.style.display = 'none';
idle = false;
document.getElementById("alert").innerHTML = '';
if(!countdownrunning)
setTimeout('startCountDown()',2000);
countdownrunning = true;
}

</script>
my code here...after modified a bit...it works for me...
var startSeconds = 10;
var milisec = 0;
var seconds=startSeconds;
var countdownrunning = false
var idle = false;
document.counter.timer.value=startSeconds;
function CountDown()
{
if(idle == true)
{
if (milisec<=0)
{
milisec=9
seconds-=1
}
if (seconds<=-1)
{
document.location='../login/logout.php';
milisec=0
seconds+=1
return;
}
else
seconds-=1;
setTimeout("CountDown()",1000);
}
else
{
return;
}
}
function startCountDown()
{
seconds = startSeconds;
milisec = 0
idle = true;
CountDown();
document.getElementById("alert").innerHTML = 'You are idle. you will be logged out after ' + startSeconds + ' seconds.';
countdownrunning = false;
}
function resetTimer()
{
idle = false;
if(countdownrunning)
setTimeout('startCountDown()',2000);
countdownrunning = true;
}
