See the two commented lines below, that is where you can insert code for things to do when the user goes idle, and when the user comes back. Set the idle period on the third line, 1000 = 1 second.
idleTimer = null;
idleState = false;
idleWait = 2000;
(function ($) {
$(document).ready(function () {
$('*').bind('mousemove keydown scroll', function () {
clearTimeout(idleTimer);
if (idleState == true) {
// Reactivated event
$("body").append("<p>Welcome Back.</p>");
}
idleState = false;
idleTimer = setTimeout(function () {
// Idle Event
$("body").append("<p>You've been idle for " + idleWait/1000 + " seconds.</p>");
idleState = true; }, idleWait);
});
$("body").trigger("mousemove");
});
}) (jQuery)
This works by using a setTimeout function to fire at the end of the specified seconds. If basically anything happens during that time (the mouse moves, the page is scrolled, or a key is pressed) the timeout period is reset.
Very cool idea, but in Google Chrome v4.0.302.2 the demo just loops “You’ve been idle for 2 seconds.” and “Welcome Back.” every 10 seconds or so.
What OS? I’m running the latest version on Linux and Windows and the code’s running as it should.
I’m on Windows Vista. If I move my mouse it correctly assumes I’m back, but if I don’t touch anything it will incorrectly assume I’m back after about 10 seconds.
Odd. Unfortunately, I can’t test Vista here.
Does the 10second gap increase if you increase idleWait?
Works fine for me! Tried it on FF3.6 and Chrome 4.0.249.43 on Ubuntu 9.10.
Have a look @ jsbin.com/uxoya
Works fine on Chrome 4.0.249 (Mac OSX Snow Leo)
Just incase people are wonderiing, this code has two main purposes; having the ability to execute CPU-heavy tasks when the user is not active, or vice-versa;
save processing by disabling expensive script until the user returns.
Live examples include Facebook, who stop AJAX page updates when idle, and the web version of GTalk (integrated into email), which uses the state to show user status to thers.
Doesnt work with IE8 and Chrome on Windows7, it does work with FireFox.
Can someone help me to modify that script so that on his Iddle state, it loads a page passing something with get method, like “test.php?name=johndoe” ???
Cool snippet.
You should also add click events to the bind event.
Thanks! I used this on http://mixedminds.com to hide my “scroll-to-top” button when the used is idle, so the button won’t obstruct content on mobile devices. As soon as the user is “active” again, the button shows, as long as the window scrollTop() > 150.
How would you go about keeping track of the actual seconds that have passed by (as opposed to always having a message appended to the HTML document with 2 seconds)? I attempted to use the
setInterval()
function, but it returned some really odd values. Any ideas? Thank you in advance.Thank you,
I modified this slightly to logout inactive users by using alert when the user clicks okay they are redirected to the logout page subsequently then redirected to the login page.
idleTimer = null;
idleState = false;
idleWait = 240000;
(function ($) { $(document).ready(function () {
$('*').bind('mousemove keydown scroll', function () {
clearTimeout(idleTimer);
if (idleState == true) {
// Reactivated event
window.location.replace("logout.php");
}
idleState = false;
idleTimer = setTimeout(function () {
// Idle Event
alert("You've been idle for " + idleWait/60000 + " mins.");
idleState = true; }, idleWait);
});
$("body").trigger("mousemove");
});
})
Thank you ,

Found a working snippet and included in JQuery Mobile app and it’s working and thanks for the article.
is there a way to detect if the user has moved to another window if the browser window is not active or the user’s not on it its open bout not in focus then it will run a function. Thank you
Thanks, Chris! I found this super helpful. Also, .bind() has been replaced by .on().
“As of jQuery 3.0, .bind() has been deprecated. It was superseded by the .on() method for attaching event handlers to a document.”

Thank you for your code.I have a query :) if page is opened in multiple tabs and mouse active in any of the tab. It should not go idle in any tabs . Please I need a solution for this.
For multiple tabs – use local storage or a cookie to store the time – not sure about the performance implications – debounce probs.
