(7 answers)
Closed 9 years ago.
I want to track event which fire on, when user hits back button on the browser.
I found many post related this but all suggest use of .onbeforeunload event. but this event also fire on, when page is refresh or browser window is closed.
If there is any idea to track only browser back event.
Thanks for your help...!!!
You can use History.js:

History.js gracefully supports the HTML5 History/State APIs
(pushState, replaceState, onPopState) in all browsers

About the popstate, the documentation says this:
Note that just calling history.pushState() or history.replaceState()
won't trigger a popstate event. The popstate event is only triggered
by doing a browser action such as a click on the back button (or
calling history.back() in JavaScript).
So for example, at youtube, if you navigate to another video, the url is changed but how can i detect that change since it wasn't triggered by a browser action?
I would like to do this at the content script, but if impossible, i could do it in the background.
PS:Youtube is just the easiest example of this, so youtube specific solutions, or solutions that depend on youtube maintaining certain id's in the html are not what i'm looking for.
You can use webNavigation API and listen for onHistoryStateUpdated event in your background.
e.g:
chrome.webNavigation.onHistoryStateUpdated.addListener(function () {
// do something here
})

I am currently looking at the "unload" event of a window to try to determine how the "unload" event was triggered, but am having little success. Is there a way to determine how the javascript event was triggered?
Page Refresh
Back Button (or navigate away from the page)
Closing the Browser
Essentially I need to execute some code only when the browser window is being closed, not refreshed or navigated away from.
Purpose: When a customer does an update of our software, the update will redirect their first Internet request to an offer page. There is a button for a "Do Not Bother" option, but some users will simply close their browser. Upon closing the browser, I need to duplicate the "Do Not Bother" functionality so the user no longer gets redirected to the offer page. Simply attaching to the "unload" event will not work due to the different ways of leaving a page.
No, and if there was it would be browser dependent.
What kind of code are you trying to run when the user closes the page?
Is it to logout the user?
Then the user would not be logged out if the browser crashes or the network connection breaks (and probably not if the computer goes to sleep/hibernation mode).
If it is for logout-purposes you should probably use a timestamp variable at the server that gets updated with every request (or use a ajax-ping), and logout the user if it hasn't been seen for a specified time.
Update: Found this answer here at stackoverflow.
Yes, there is a solution!
I've designed a solution based on onBeforeUnload+onLoad events, HTML5 local storage and client/server communication. See the details on https://stackoverflow.com/a/13916847/698168.
I use a method of doing keyboard "sniffing", in that it looks for keydown's of "F5", "ctrl+r", "alt-f4", "backspace" and others, and if it finds them flowing through the keyboard event queue, it sets boolean variables appropriately to trap that status... then I use a "onbeforeunload" function handler, which tests against those boolean status variables to decide what to do.
You can even shut down various keyboard strokes (like "ctrl+n" or "F1" for instance) by using preventDefault(), bubbles=false and returnValue=false in your keyboard handling.
This stuff is not for the faint of heart, but its certainly doable with some persistence and lots of cross browser testing!

JavaScript, browsers, window close - send an AJAX request or run a script on window closing

I am working on a website, where at a time one admin can login. I implemented this by saving value in database. Now the problem is when current admin forget to logout, the value in database do not change and another admin can't login again. Even this current admin can't login later on, cause the value in database is checked in condition.
I have looked in window.onbeforeload and window.onunload functions, but it only trigger on page refresh etc, not detecting browser close tab/window. I want to detect closing browser tab and call function upon close, so I can change value in database using ajax.
Any help will be appreciated! Thanks
The event you are looking for is onbeforeunload
Use window.uneforeunload which is trigged when tab/window is closed.
Updated
window.onbeforeunload = function (){
// update your database from here before page closed
}

Event onBrowserClose for Google Chrome?
Is it possible to detect when the user exits the Chrome browser, so I can process some data right before they exit? I have looked into using chrome.windows.onRemoved.addListener(function(integer windowId) {...}); but it only listens for a window and not the entire browser.
Well, no.
There is no Close event, and Chrome doesn't guarantee that all others pending events will be fired before closing (will be fired at all).
I personally researched this topic while writing the "History Eliminator" extension, that would erase your browser history on close.
