It's possible to show some message on the page when you set mouse cursor on the browser back button? I don't want to use window.onbeforeunload, because it's irritating. I use ajax and I want to inform users that if they want to go back to the previous page on my web portal they should use a different button.
Is it possible to do it?
Thanks for your help
It is not possible to handle the mouse moving on the browser buttons, these are not part of the DOM that your scripts can handle.
There is an answer available here, which proposes a way of preventing users going back through the browser's back button.

I am creating a web app using web socket, which on user closes the tab I will make an API call to the server to clean the user related info in the server, I used onBeforeUnload listener in javascript, but this method also gets triggered during the page refresh.
I need to trigger a method only during the tab or browser close, but not during the page refresh.
I know this question has been asked several times, some solution suggested using cookies will not be helpful in my case
navigator.sendBeacon() method can be used for sending data from browser to server when a tab is closed.
Here is an example:
window.addEventListener("unload", function informServer() {
navigator.sendBeacon("/server-api-to-collect-data", my-data)
})

As far as I know, you can not listen to actions of browser's tab close or exits. For your application it is an "unload", whatever caused it...
The only thing I could think about is maybe add a listener for keyboard key press (F5), however it doesn't help in case someone refreshed by clicking on the browser's refresh button.
I don't know what is the use case, but most of the things should be done when a page unloads (no matter why) and/or when the page is back up again. So most of the solutions are for situations where your page is loaded again - and then you can determine what was the source of the load and make farther actions, but since you have an option were someone can close and never come back, that might not be the case.
Some solutions for page load up:
You can use Navigation type.
You can check referer.
You can use cookies or other types of browser storage.
I would recommend to rethink about your use case. Maybe you can do whatever you want on load up or leave it on onBeforeUnLoad without knowing the future :)
I´m currently using Sammy.js in my Single Page Application and want to notify the user if he tries to leave a site with changed content.
Is it somehow possible to intercept the back command or any other routing change to display some hint before?
See my answer here for one way to do what you're looking for. The group I work for actively uses this technique to show a dialog whenever a user tries to navigate away from a page that has been modified but not saved.
Outside of the solution I point out there, you cannot prevent the back button from actually navigating them. If you could do that with JavaScript, that could be easily abused to keep users on a page until they closed the browser.
Hi I'm wondering if there is a way to give window.history.go(-1) a default back page? If you enter a page directly from another site and someone clicks the back button, I don't want to direct them back to the referring site, I'd rather redirect them back to a search page within my application. I notice on some sites they are somehow reading the previous session, is that an option or no? Thanks
may be try something like this:
Back
I think you might be interested in the window onbeforeunload event.
Have a look at this thread: using onbeforeunload event, url change on selecting stay on this page
Using Javascript is it possible to hook a custom function to the browser back button while preventing the default event?
So simply put, the user clicks the browser back button, and instead of being taken back to the previous page on my site, my function fires. My aim is not to to prevent the user leaving my site.
Something like the below pseudo code:
window.backbutton.click(function(e){ preventDefault(e); myFunc(); })
FYI What I actually have is an internal back/forward system controlled by buttons within the view and I'd like to trigger my buttons when user clicks browser back.
You should look into Browser History https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Manipulating_the_browser_history . It is a new standard for emulating pages (back and forward) on a single-page site.
you can do this
$(window).bind("beforeunload", function() {
return "Are you Sure you want to do this even though there are internal navigation buttons? if you do whatever you have done so far
will be gone unless it has been completed and/or submitted "; //
Return whatever message you want
});
Edit: this method displays a confirmation with the message and
automatically places buttons in the confirmation window
the author also clearly stated he does not want to prevent users from
leaving his site
see js fiddle http://jsfiddle.net/JW9fX/
Aaron - "updated question, I do not want to prevent them leaving my
site – Aaron 27 mins ago"
Edit: there is no definitive way to display a message only on the back
button in my knowledge i have also looked and have seen the only
methods that pick up on the back button are
$(window).bind("beforeunload",function(){return;}) and
$(window).onbeforeunload = function(){return;} and they both pick up
on when the page is refreshed or any other navigation away from the
current page. This is currently the best answer that can be provided
in the year 2014
Edit:
above is for all unload events
http://jsfiddle.net/Lhw2x/85/
been messing with that through all its lower objects it cant be done through javascript till someone decides to make all major browsers use a specific name for each unload event instead of it just being an unload event
so the answer is no you cannot hook a custom function to the browser back button while preventing the default event using javascript
i want to know is there any way we can know browser's events.. like : clicking on BACK button, FORWARD button, REFRESH button by javascript.
These specific browser events are not available as it would be vulnerable to severe privacy violations. Privacy is something browser vendors hold sacred and a key selling (proverbial) point. All browsers allow you to know is when a user enters or leaves your page for which Kamui pointed out the technical details.
Within the same site, it's possible to achieve some browser event tracking using cookies and javascript. For example track wether users click on a hyperlink and label it as a forward event and when a user leaves the page without clicking on a hyperlink it could be one of:
browser url input
back action
javascript location.href replace
The location.href replace can be tracked as well when you have full control over all javascript, just use a helper method with tracking code instead of directly chaning location.href.
That leaves browser url input and the back action. With cookies and request headers (getting the referrer) it is possible to get close to finding out the forward and back events, though not 100%, but pragmatically, 99% sure is good enough.
Figuring out the refresh event is easy with request headers (referrer), if the current url matches the referrrer, it's a refresh event.
Now I offer no code or definite solution, but I outlined what you could do to track back, forward and refresh events within a single domain context. It won't be a quick and easy way to implement it and as far as I know, there's no framework in existance that reliably tracks browser events or even comes close to what I described above.
A more common/lazy technique to achieve something similar is to create a single page app, for which there are many frameworks available. Just google single page app framework, but thats a pretty heavy solution with other implications that I won't go into now.
You can not capture (for example run some piece of code when user presses Back button) them, however, you can direct your pages in history by using:
history.go
history.back
history.forward
More about JS History object.
As #sarfraz says you cannot capture the back and forward button clicks but you could call
window.onbeforeunload = function(){alert("you just tried to leave the page");};
which should be triggered when either the back/forward/refresh buttons are clicked to perform an action, unfortunately you can't tell if they are going back or forward. Please note don't alert a message it's really annoying when trying to exit a page.
EDIT
you can also do this in jQuery if you have it
$(window).unload( function () { alert("Bye now!"); } );
