I want to pop up a dialog before an html page is unloaded asking to unload page or not. If yes is selected then the unload continues, and if no is selected then the unload event is canceled.
You can't set the text to "yes"/"no" (it'll be "Ok"/"Cancel" in most browsers), but you can prompt (be careful when using this) when leaving the page in any manner using window.onbeforeunload, like this:
window.onbeforeunload = function() {
return "Are you sure you wish to leave the page?";
}
Only use this if you have a good reason, don't annoy your users. That being said, this will prompt when leaving the page, that includes history back, forward, refresh, closing the window/tab, clicking a link to navigate away or submitting a form, etc. So you'll probably want to call this when going somewhere that shouldn't prompt:
window.onbeforeunload = null;
For example, submitting a form of information, you'd want to prompt when leaving/losing the data, but not when actually submitting it.

I'm trying to confirm before user leaves the page and I used this solution
<script>
window.onbeforeunload = function(){
return 'Are you sure you want to leave?';
};
</script>
but this only works when you interact with something on the page like maybe a clicking or typing, it doesn't work when you directly close the page
and I made a logging only popup page i.e. there is nothing on the page to interact with, so how do I still get it to confirm before leaving?
In the docs
According to the specification, to show the confirmation dialog an event handler should call preventDefault() on the event.
So, you should at least do
window.onbeforeunload = function(e){
e.preventDefault();
return 'Are you sure you want to leave?';
};
However the docs also state
To combat unwanted pop-ups, browsers may not display prompts created in beforeunload event handlers unless the page has been interacted with, or may even not display them at all.
So you might be all out of luck with a completely empty page you have not interacted with.
I'm building a text editor in my website, the workflow is as follows.
In /list, the user picks an entry they want to edit from a list which takes them to /edit/[article_id].
The user does their work, and then clicks submit.
The server processes the thing, and redirects them back to /edit/[article_id] which by now reflects the edited work. The server also activates a flash message on the page to indicate the edit was successful.
By this point, the user probably wants to go back to /list and clicks the browser's Back button. This will take them back to the editor repeatedly depending on how many times they submitted.
I've tried putting a Back button somewhere on the page, but a good many users simply ignore it.
I'd rather not make the submission posted via AJAX, since that would also affect the flash message system.
What I like to do, is replace the last entry on the history list when the user submits, without changing its length. Is it possible?
Try this
window.location.replace(url);
after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.
Use window.close():
close();
Note: the current tab is implied. This is equivalent:
window.close();
or you can specify a different window.
So:
function close_window() {
if (confirm("Close Window?")) {
close();
}
}
with HTML:
close
or:
close
You return false here to prevent the default behavior for the event. Otherwise the browser will attempt to go to that URL (which it obviously isn't).
Basically what i am trying to do was, whenever a user tries to close the current tab(when he was on my site), i want to display a pop up with three choices about why he was leaving and want to store that choice some where
So i have written the following in main.js which will be loaded through entire site pages
$(document).ready(function() {
// Before closing the current tab, ask user for a reason
$(window).on('beforeunload', function(event){
$('#load_choices_up').click();
event.stopPropagation();
event.preventDefault();
debugger;
});
});
So i have three issues with the above jquery code
*.This code was executing even when i click another link on the same page(I mean if i navigate to another page from current page), but i only want this code to run when the current tab/page was closed(about to close) completely, but not when navigating to another page on my site
*. After this line $('#load_choices_up').click() was executed, a choices pop up was opening as expected, but immediately the default processing of browser(that is closing functionality) was not being stopped with two lines event.stopPropagation(); and event.preventDefault();, i mean these two methods of stopping the behaviour is not working and the browser is closed, but i want to do some processing based on user choices input and then based on that i will close tab.
*. When i used return "Why do you want to leave the page", instead of choices pop up, the browser was displaying different message based on browser type like "You have unsaved changes" in chrome, and some different message in firefox, instead of displaying my custom message
So finally, why event.stopPropagation(); and event.preventDefault(); are not working ? and why i can't able to display my custom message ?
You can't prevent someone from closing the browser. This is for obvious security reasons. Imagine a spam-website preventing you from closing the website while pumping you full of god knows what.
You can at most pull one function like an alert() or a prompt. After a user closes them, the tab will close either way.
beforeUnload is also extremely short-timed. You won't be able to run massive scripts with it, as the user would probably close the tap before any script would run properly. (I tried it with an ajax call, didn't work)
So, even if you're able to get the options you want in there, the moment a user chooses one of the options, you're not going to be able to save it anywhere. Your script will never make it that far.
You can customize the "are you sure?" message like so:
$(document).ready(function() {
window.onbeforeunload = function(e) {
return 'Dialog text here.';
};
});
but again, you can only change the text. It's a browser's native functionality, and you cannot change it.
I am looking to develop a small popup message which acts similar to the window.beforeunload function, to notify the user, that if they leave the current page, they will lose all of their data.
However the issue with the beforeunload event is it fires to often.
I would like to have the popup message fire only when a user closes the page, or clicks a link which takes them away from the current page, to ensure they are aware that their current action will result in the loss of the form data they have entered so far.
However beforeunload event goes further to fire when they refresh the page, which is not needed for this case, and also when the forum is submitted.
Could anyone advise me on the best way to develop this. I thought about using a basic confirm dialog and have it fire under the right circumstances, however is it possible to know if the user is refreshing the page, and if the forum is being submitted (without jQuery).
How can I have this dialog fire at the appropriate times?
Unfortunately, I don't think this is possible. The page unload events are very limited, for security reasons.
If you only want it to appear if the user added or changed formdata, why not check for changes in the data? If yes then return the question on beforeunload, if not do nothing.
Assuming that the form isn't too complicated, you could save form data by using Ajax call, which means there will not be a page reload. So, beforeunload will then behave as it was designed to.
If a user clicks the browser's back button, then I want a prompt to appear and ask for confirmation. If the user clicks 'OK', then it should navigate to xx.html. If the user clicks 'Cancel', then it should prevent the navigation. How can I do this?
Note: Already I tried the onbeforeunload method, but it is working for all the navigation actions. For Example, clicking the link on the page will also fire this event and show the message to the user.
You can't. The best you can do is use onbeforeunload and remove that event when clicking on a normal link:
<script type="text/javascript">
window.onbeforeunload = function() {return "Are you sure?"}
</script>
Leave
There's no way to differentiate between navigational actions in the onbeforeunload event. You could disable it for all links/forms on the page by removing the window.onbeforeunload handler in each link's onclick handler, or onsubmit for forms. However, you will still be unable to tell whether the user clicked back, forward, a bookmark, etc or typed a new address into the address bar.
Firstly, you need to capture the "beforeunload" event (which previous answers here did).
// Display browser warning message when back/forward/reload or hyperlink navigation occurs
$(window).on('beforeunload', function(e) {
console.log('page navigation captured');
return 'By leaving this page you will lose the data you have entered here.';
});
More importantly, you want to allow non-disrupted navigation from certain elements (e.g. links with class "allow-navigation"). The way to achieve is to remove the event-handler when your links of choice are clicked.
// Disable capture for certain elements
$('.allow-navigation').on('click', function(e) {
$(window).off('beforeunload');
console.log('page navigation allowed');
});
Will work for your links of the type:
Click me
This way you can control the page navigation. Browser back/forward/etc still open the confirmation box. But the links you choose will work without any disruption.
Hope this helps.
you can do this
$(window).bind("beforeunload", function() {
return "Are you Sure you want to leave this page?"; // Return whatever message you want
});
also if xx.html is the page in their history than you dont need to add
anything just return a message it will automatically put buttons for
you
Edit: see fiddle before you assume it does not answer the question
asked http://jsfiddle.net/Lxq93/
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 force a navigation to a specific page when they click okay on the confirmation when they try to go to a different page
and back button does not have a specific event name it shares its event with several different events all in the unload event so you cannot make a back button specific function through javascript
