I am having a problem to detect a click event outside document, for instance in the closing button of the browser without using the onbeforeunload event, because I have a JSP page that is processing something, using meta refresh to give the status of the process evolution.
Since I am using meta refresh I cannot use window.onbeforeunload event to prevent/confirm the user to exit because the meta refresh will fire up the event. Thus, I need to check manually if the mouse will be clicked outside my document.
I can check if the mouse coordinates are outside, thus can´t associate an click event to that in IE8.
if (window.event.clientY < 82 && window.onclick)
Someone have any idea out achieve this issue?
Thanks in advance!
Detecting the close button isn't possible but you can detect if the user is losing focus of the browser by doing:
$(window).blur(function() {
alert('lost focus');
}
It's not possible. Events don't fire outside of the document, including clicks on the window chrome.
I think you will need to think about what you're trying to achieve. It sounds like a shaky design if you must get the close event of the page. Lots of other events will affect you if that is of a concern.
If you have a JSP page producing and showing the status by a meta refresh - what is your problem with the window closing? That should be of your concern, not how to detect a browser close event.

A <div tabindex="-1"> element might have a focusout listener on it.
The event will fire whenever the focus changes to another element (or nothing) in the page.
However, it will also fire whenever the containing browser tab or window loses focus. This can be caused by a number of things: ALT+TAB, the WINDOWS key, the user mouse-clicking on another application, or the user opening the developer console.
When handling the FocusEvent, is there any way to distinguish between the event being fired due to focus change within the page or outside the page?
As an aside, FocusEvent.relatedTarget is available. However, it seems to be null both when focus goes outside the page and sometimes when it goes to another part inside the page (i.e. an element which cannot 'receive' focus as such). UIEvent.sourceCapabilities also seems to be available, and seems to reliably go null when the page as a whole loses focus, but I'm unsure how reliable this would be for solving this problem.
Any help would be much appreciated.
You could use the Page Visibility API to see if the window/tab has user focus

window.onbeforeunload = goodbye;
I currently use the code above to detect the onbeforeunload event, but I'm wondering if there is a way to use the event object that was passed in to determine if the event was fired due to the back button being pressed or if it was from the user attempting to reload the page.
There is no life or death scenario here as Chrome (possibly others) tailors the text of the button.
I'd simply like to the tailor the message that I display...and it's bugging me that I can't find it when looking through the object in Chrome.
I know it's possible to detect right before a user closes a webpage using onbeforeunload. I was just wondering if there was a similar event fired right before the user switches tabs or minimizes. I'm not looking for an event that fires after the user changes tabs.
Is this possible?
No, there is no such event. Sorry!
I want to run some Javascript when the user clicks the Stop Load-button (red X in most browsers) or hit Esc on the keyboard, which usually does the same.
I've seen questions here covering the Esc button by hooking onto document.body.onkeyup, but couldn't find anything covering mouse click on the Stop button.
Internet Explorer has a document.onstop event that is fired, but other browsers don't seem to support that. Note that it's fired when the user clicks Stop or hits Esc, OR if the user navigates to another page during page load, which has the same effect.
I don't believe there is a reliable way to trigger an event on clicking Stop in other browsers. Perhaps it would be possible to do something like: keeping the connection to the server open (as in the Comet approach), streaming some sort of keep-alive down the connection, and detecting if the stream ends (as I assume it would if the Stop button were clicked).
If it's images that are still getting loaded on the page, you can use the onabort event to monitor for the stop load.
Monitoring for the mouse click should be impossible, as it doesn't happen inside the current browsing window.
There isn't any cross browser way of doing this.
However, IE has a special event, onstop which occurs on the body when the stop button is pressed. You cannot override the stop button functionality (that is, you cannot cancel it), but you can detect that it has happened in IE.
i'm looking for a reliable way on how to detect when a user closes the browser/tab in order to display a warning message (i'm having a shopping cart which uses sessions).
i've googled and couldn't find a proper solution - window.onunload will display a message every time i'm refreshing the page ..
any ideas?
thanks
You can't tell the difference between closing, reloading, back/forward etc.
beforeunload is fired on all of them.
Depending on if you launched the window yourself, you could run your code before calling window.close(), but this won't be called if the user closes the window themselves.
I don't believe such a thing is possible.
The browser can fire an event when the page (un)loads, but who's to say wether the user is navigating, or closing the browser/tab?
