Activity includes keyboard activity and mouse movement. The value of timePeriod in the example script represents 5 seconds (5000 milliseconds). Change to suit. For example 5 minutes = 300000 (1000 ms * 60 seconds * 5 minutes). The variable "warnPeriod" sets the amount of time that the warning div will appear before the window closes if the timer isn't reset.
Step 1. Enter script below on Between Head Tags tab in Layout HTML. Note: use MasterBorder HTML if you wish to apply script to pages sharing a common Master Border
<SCRIPT LANGUAGE="JavaScript">
<!--
var autoCloseTimer;
var timeoutObject;
var timePeriod = 5000; // 5 seconds
var warnPeriod = 15000; // 15 seconds
function promptForClose() {
autoCloseDiv.style.display = 'block';
autoCloseTimer = setTimeout("definitelyClose()",warnPeriod);
}
function autoClose() {
autoCloseDiv.style.display = 'block'; //shows message on page
autoCloseTimer = setTimeout("definitelyClose()",timePeriod); //starts countdown to closure
}
function cancelClose() {
clearTimeout(autoCloseTimer); //stops auto-close timer
autoCloseDiv.style.display = 'none'; //hides message
}
function resetTimeout() {
clearTimeout(timeoutObject); //stops timer
timeoutObject = setTimeout("promptForClose()",timePeriod); //restarts timer from 0
}
function definitelyClose() {
top.opener = self;
top.window.close();
}
-->
</SCRIPT>
Step 2. Enter following code on Inside Body Tag in Layout HTML (all on one line)
onkeydown="resetTimeout();" onmousedown='resetTimeout();' onload="timeoutObject=setTimeout('promptForClose()',timePeriod);" Step 3.
a) Place a text box on your page where you want warning to appear.
b) Press Ctrl+T and paste in the DIV code below. Feel free to modify the appearance.
Change text to match actual time period set in script.
The contents of the div only appear when the timer runs down.
Clicking on cancel closes the div and resets the timer.
<div id='autoCloseDiv' style="display:none">
<center><p>Inactivity warning!<br>This window will autoclose in 15 seconds unless you hit 'Cancel.'</p>
<input type='button' value='Close' onclick='definitelyClose();' />
<input type='button' value='Cancel' onclick='cancelClose();' />
</center>
</div>
