Why do blur event not working?

This are the code that I currently have:
var interval;
function printPageState() {
console.log("active");
}
window.onfocus = function() {
console.log("focus");
clearInterval(interval);
interval = setInterval(printPageState, 2000);
};
window.onblur = function() {
console.log("blur");
clearInterval(interval);
};
window.onscroll = function() {
console.log("scroll");
if (!document.hasFocus())
document.getElementById("some-id").focus();
clearInterval(interval);
interval = setInterval(printPageState, 2000);
};
I'm attempting to create a user attention checker/page-pinging like functionality. the checker currently has an event handler for blur, focus, and scroll event.
And I'm having the problem that was stated above when the following stuff are met.
Your browser had some viewable part on the browser view port which make it possible to scroll even if the page was not in focus.
The page was out of focus and or blur event was already fired.
I want to stop the interval but the blur event was not firing anymore as the browser isn't focus so I tried to force the focus state on one of the element but no locky it wasn't working.
Do the following issue to replicate the issue:
Open the page in minimized browser > then focus out the page.
Scroll on the visible browser view port but do not click (which won't make focus state true).

How to dismiss bootstrap modal if no action in browser

I want to dismiss bootstrap modal if no action in browser screen for 10-15 seconds.
I have tried settimeout() function but this will not check the action in the browser.
setTimeout(function() {$('#form').modal('hide');}, 10000);
So, Is there any way to hide modal box if no action in the browser?

The snippet below with set the flag actionAppeared if there a keypress in the keyboard or 'mousemove' in the mouse.
var actionAppeared = false;
jQuery(document).mousemove(function (e) { actionAppeared = true; });
jQuery(document).keypress(function (e) { actionAppeared = true; });
setTimeout(function() {
if(!actionAppeared) {
$('#form').modal('hide');}
}
, 10000);
Here is a working demo. Open the console to see the mousemove and keypress events.
The mousemove events is triggered really easy so to test it open the modal and quickly move the cursor away from the keyboard.

Capture all click events and discard unallowed

I develop a web GUI for a special tablet. This tablet is running with Linux and the used browser is Chromium. The application is a web application with PHP, HTML5, JQuery and JavaScript. Now I run into a problem. The screen is a touchscreen and the user is able to navigate through the application by touch the screen. However now we decided to add a feature for saving electricity. This feature will shutdown the background light after three minutes. To turn on the backlight again, the user should touch the screen again. This leads to this problem, because on any touch the buttons are also pressed even if the background light is shutdown. I want to prevent this by discarding all clicks on the touchscreen if a cookie is set. If this cookie is not set the touchscreen and the application should work as desired. How can I solve this problem?
I installed an event listener to register all clicks and to reset the time.
window.addEventListener('mousedown', function(e){
$.get('php/timeupdate.php', function(){});
}, false);
Code used to stop the execution:
$(document).on('click', function(event) {
$.get('php/getwakeup.php', function(e){
if(e==='true'){
//event.preventDefault(); // I tried all three possibilities
//event.stopImmediatePropagation();
event.stopPropagation();
}
});
});

You can try this:
$(document).on('click', function(event) {
// get your cookie
if( cookie is set ) {
event.stopPropagation();
}
});
event.stopPropagation(); stops every event handling from where you called it =)
EDIT:
You have to set your $.get call synchronous or do it completely diffrent. Take a look at the jQuery.Ajax documenation. There is a parameter called "async".
But be careful unless the call is ready nothing else will be executed on you page! So if your script doesn't answer nothing else will work on your site.
The better solution would be setting ja recurring call that will get the information you need. Set it to every two seconds (setInterval is your friend here). If your response is true than set a global variable that you can check in your onDocumentClick event.
window.isBacklightOff = false;
setInterval(function() {
$.get('php/timeupdate.php', function(e) { window.isBacklightOff = !!e; })
}, 2000);
$(document).on('click', function(event) {
// get your cookie
if( window.isBacklightOff === true ) {
event.stopPropagation();
}
});

When the back light goes off you can set some flag handleEvents=false;
So when the flag is on don't handle any events.
Now when the back light is on you can set handleEvents = true.
$(document).on('click', function(event) {
// get your flag say handleEvents
if( !handleEvents ) {
event.stopImmediatePropagation();
return;
} else {
//do your biz logic send ajax..etc
}
});
Reason why your code above is not working:
$(document).on('click', function(event) {
$.get('php/getwakeup.php', function(e){
if(e==='true'){
//event.preventDefault(); // I tried all three possibilities
//event.stopImmediatePropagation();
event.stopPropagation();
}
});
});
The function inside $.get is async and called on success in that you are setting the event to stop propagating...well by that time when the success function is called the event is already complete and has called all the listeners.
So in short you must not do the event stop propagation inside the success function.

Having issues with session timeout

Need your valuable feedback on this. I have implemented idletimeout functionalty so that session will expire in 3 minutes if the user is idle.
In three scenario, I am resetting the timer.
On click or tap
after 2 seconds while processing is in progress
on scroll or scrollstart
The problem is sometimes session is getting timeout before the 3 minutes even if I tap, click or scroll and user is redirected to login page even if the function is gets called on tap click or scroll and resettimers is getting called. I am facing a bit hard time to figure out the loophole.
I am posting the code; please let me know if you notice anything.
// Set timeout variables.
var timoutNow = 180000 ;
var ua = navigator.userAgent;
var event = ((ua.match(/iPad/i)) || (ua.match(/iPhone/i)) || (ua.match(/iPod/i))) ? 'touchstart' : 'click';
var logoutUrl = Mobile+'/login.html'; // URL to logout page.
var timeoutTimer;
// Start timers.
function StartTimers() {
timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
//console.log(timoutNow);
}
// Reset timers.
function ResetTimers() {
clearTimeout(timeoutTimer);
StartTimers();
}
// Processing time check.
function Laodtimercheck()
{
setInterval(function(){
if($("body").hasClass("loading-processing")==true)
{
ResetTimers();
}
}, 2000);
}
// Logout the user.
function IdleTimeout() {
sessionStorage.clear();
document.location.href = Mobile+'/login.html';
}
$(document).live(event, function(){
//console.log("Reset timers: ON TAP OR CLICK");
ResetTimers();
});
$(document).mouseover(function() {
//console.log("Reset timers: ONMOUSEOVER");
ResetTimers();
});
$(window).scroll(function() {
//console.log("Reset timers: SCROLL");
ResetTimers();
});
$(document).live("scrollstart", function(){
//console.log("Reset timers: SCROLLSTART");
ResetTimers();
});
EDIT: setTimeout only working first two times; next time ResetTimers are getting invoked but the setTimeout is not working or I might be missing something here as the session is getting timed out as per pervious two call time only....

The real problem that you're having is the folowing: "ResetTimers" not being invoke enough.
Why is not being invoked enough? I'll try to answer that.
All the logic is Ok with a few exceptions. There are two "problematic" events that not work or I think don't work like you want.
1.- LIVE (event)
That event is not being fired never. You cannot attach a live event to a document, yo need to specify a node, like html or body.
$("body").live(event, function(){
//console.log("Reset timers: ON TAP OR CLICK");
ResetTimers();
});
That's why when clicked the timer don't reset.
Another (and recomended) way to use a variable for binding events is to use .delegate().
Since jQuery 1.4.3+ is the recomended way of doing this.
$(document).delegate("body", event, function(){
//console.log("Reset timers: ON TAP OR CLICK (delegate)");
ResetTimers();
});
Any of those (live on body or delegate) would work and timer get reset on click or tap event.
2.- MOUSEOVER
There isn't a problem per se with this event, but I think it would be insuficient. MouseOver only fires where the pointer get on screen first time, if the mouse don't leave the window the mouseover never fires again. Maybe, a better or added way of control "mouse hovering" on the document is to use onmousemove event. Like I said in a comment before, I don't know if you want to be strict on this, so I left you a proposal and let's see if it fits your needs.
$(document).mouseover(function() {
console.log("Reset timers: ONMOUSEOVER");
ResetTimers();
});
In my tests, events get fires a lot, and the timers get reset on each event without problems. I hope it helps you.

Using jQuery to recall a function window onblur+ onfocus

hI got a problem to use jQuery to recall afunction if window is on focus.
And when window is not on focus (onblur) so pause that function until window is on focus again.
Here is my code:
function functiondosomething (user_id) {
var myInterval;
var time_delay = 1000;
$(window).focus(function () {
setTimeout(function() { functiondosomething (user_id); }, time_delay);
}).blur(function () {
clearTimeout(myInterval); // Clearing interval on window blur
});
setTimeout(function() { functiondosomething (user_id); }, time_delay);// ## problem here
}
My problem is :
When I remove that line (which I marked problem here above.) the
function will not work at first time until I click out of window to
make it onblur and come back on focus again, so it starting to work.
If I let that line (which I marked problem here above.) be there,
the function could not pause, even I click out of window to make it
be onblur.
When I click onfocus it start working and stop. I have to click out
of window and focus the window again again and again. Something like it need to be activate by clicking out of window and clicking back to window again.
What should I do ?

I see a few problems here:
You're not setting myInterval so when you call clearTimeout(myInterval) it's not clearing anything.
You're using the same function to set up your listeners and call setTimeout recursively. This means your handlers are being set every time you recur, and the recursion means it will run whether the handlers run or not.
I think you need to separate things a bit:
function functiondosomething(user_id) {
// Do stuff...
}
function setupHandlers(user_id) {
var myInterval;
var time_delay = 1000;
function doSomethingWrapper() {
functiondosomething(user_id);
myInterval = setTimeout(doSomethingWrapper, time_delay);
}
$(window).focus(function () {
doSomethingWrapper();
}).blur(function () {
clearTimeout(myInterval); // Clearing interval on window blur
});
doSomethingWrapper();
};
