Here is what I need to do:
I want to launch a popup window when the user exits the website.
I found code that detects when the user closes the window, but that same code ALSO fires when the user clicks on an internal link,
(which I don't want).
Any ideas how to do this?
I've looked everywhere and I can't find a clear solution.
This solution needs to work on all three browsers : FireFox / IE / Safari!
You can't, there is no such event that will be triggered when someone exits the site. That's why in the early 2000s someone too clever invented "pop-unders": popups that will open immediately, but will be put on the background, behind the browser's window.
Which are one of the most annoying things on the web, and the first ones that any popup blocker or antivirus will kill :) On the other side, there are legitimate uses for that, like most surveys you see (I got one from microsoft some days ago).
Never rely on popups, unless you are writing an intranet site, or one where you are sure all of your visitors will not have a popup blocker.

I created a simple JavaScript function to display my pop-up window once it loads. But it keeps on being blocked by Firefox and Google Chrome and I have to somehow enable it on the Firefox and Chrome to display the pop-up.
Are there any alternatives for this?
I have a player on the pop-up window so I have to use a pop-up to let the player play automatically. The problem is that if I put it on the page itself, once the user clicks another page the entire page reloads and the player automatically stops for a few seconds until the whole page reloads and I have to prevent this from happening.
The general rule is that popup blockers will engage if window.open or similar is invoked from javascript that is not invoked by direct user action. That is, you can call window.open in response to a button click without getting hit by the popup blocker, but if you put the same code in a timer event it will be blocked. Depth of call chain is also a factor - some older browsers only look at the immediate caller, newer browsers can backtrack a little to see if the caller's caller was a mouse click etc. Keep it as shallow as you can to avoid the popup blockers.
Please take a look at dthorpe's answer here. It covers your question.
You could try putting the player on the original page, and using something like History.js to control page changes (you could have the main page body in one wrapper div that changes, and leave the player outside of it).
Otherwise, you could try (assuming you meant a HTML5 <video> or <audio> player) downloading the data to localStorage/cookie/[other persistent storage mechanism] and have it seek everytime you change a page.
It will be hard to stop browsers from blocking your pop up window, because any way to do so is inherently exploitable; however, if you call the function to open another window from an onclick event, you may be able to circumvent some popup blockers. Also, some popup blockers allow popups when using the https protocol, although not many have this feature, and https can be hard to implement for the average website, if you don't have physical access to the server.
One other option is to open the other page in another tab (like this w3c example; you can 'click' the link with javascript).
You might also want to look at this post, as it is somewhat similar.
I only just discovered you asked this question.
Here's the answer in full.
Basically, you can simply create the popup immediately as the user event is fired, then fill it with content (your player, for instance) as you have it available.
Hi I have set up a task in my task scheduler to login to my UTM by opening a firefox window at regular intervals. When the relevant URL is loaded a auto-login GM script works on it and logs me in to UTM.
I would like to close that tab after the login is done. If I use
window.close();
It works fine but if no other tab is opened at the time, it simply closes the window.
Without going into details of UTM I would like the following -
A GM hack which closes the tab only if other tabs are already open. If it is the last tab of the window, then it should just replace it with a blank tab (so that window is not closed).
Probably GM cannot obtain any info about the other tabs, but is there any hack ?
As far as I'm aware this isn't possible, if nothing else then for security reasons: you don't spam javascript from your video streaming tab collecting all your data and submitting forms on your behalf.
Here's a thread with a solution that worked for IE7 that you may be able to manipulate but as I said it's not likely.
If you decide to have ago, don't think about identifying the number of tabs, it won't happen, instead focus on determining whether or not there are multiple tabs.
The linked example uses if(clientY == 0) to determine whether or not the browser is closing. This would be a good starting point.
Again, for security reasons, you won't be able to find out information about open tabs.
I'm building a quick VOIP demo using Skype and when I press a call button, the Skype application takes the focus away from the browser. You can try here http://developer.skype.com/skype-uris/skype-uri-tutorial-webpages where you'll find several "Try it here" links. When I click those links, I would like the browser to maintain focus. Is there a way to do this?
Thanks.
What you would need to do is apparently called "focus stealing" from my web searches.
At least as far as Windows is concerned, there does not seem to be a reliable way to do this from the browser alone.
I just googled "focus stealing" (which is what the JavaScript only solution would need to do to get this done) and found many answers showing that, though theoretically possible, depending on the configuration of Windows stealing the focus away from Skype by the browser would probably not work in the majority of cases.
The complaints in the Google links are numerous and some answers conflict, but it looks like reliably "stealing the focus" back to the browser is not going to be supported.
This is a good thing though, if you think about it - I do not personally want just any old JavaScript program running in my browser to change my focus from what I am working on back to the browser willy nilly - this would be a very annoying behavior for a web page to be able to do at best, making my system useless at worst.
If you could do it in this case using some methodology allowed in a browser, so could anyone else - even malevolent websites.
The best answer is to never let the focus leave the browser, but I have no idea how to do that in your specific case. Perhaps whatever means you are using to launch Skype may have an option or something to launch it in the background or whatever, never changing the focus.
I did not hit on specific links pertaining to Apple OSes, Linux or mobile OSes, but I have a feeling the same concerns and limitations apply for those as well.
Here are some of the links on the Google search (and sorry about the bad news for your needs):

Focus stealing is evil
http://pcsupport.about.com/od/windowsxp/ht/stealingfocus02.htm
you can open it on new window, then close the new window and refocus on yours
somthing like:
a=window.open('skype:ohadcn?chat',10,10);
//i couldn't find a relevant event, onload() do not work for me here
//so i used setTimeOut, hoping that two seconds is enough to open skype but not enough to loose the user
setTimeout(function(){ a.close();window.focus();},2000)
I went to the skype tutorial page in Chrome, brought up the console and tried Ohad's answer, but it would not return the focus to the tutorial web page.
I even tried a script to perpetually put the focus in the Search textbox:
function ASDF() {
document.getElementsByName("q")[0].focus();
setTimeout(ASDF, 1000);
}
setTimeout(ASDF, 1000);
Still no luck.
I tried changing Ohad's script so that it would reopen the tutorial page in a new window after the skype app opened. It would work if the tutoral/console page was the only tab in the window:
a=window.open('skype:ohadcn?chat',10,10);
setTimeout(function(){
a.close();
a=window.open('http://developer.skype.com/skype-uris/skype-uri-tutorial-webpages', 10, 10);
window.close();},2000);
However, if the tutorial page/console script was in window with other tabs, it did not return focus to the reopened page. Not to mention, IE might warn the user that the original page is trying to close.
I do not think there is a way to consistently achieve your goal, but I reserve the right to be wrong.
There are some video streaming sites that pop up an ad anytime you click anywhere on the page. The problem is, you have to click on the page to press play! So I was thinking of making a UserScript that disables the script that does this. The only problem is, I already disable all the scripts on the site and when I do it still pops up. Is there a way that I can disable them ? I'm also using jQuery, so if I can do it through their interface, that would be great.
edit: Two perfect examples of such sites are daclips.in and gorrilavid.in
I have Adblocker Plus, and it seems like it is not recognizing "on Click" events as pop-ups, rather normal clicked links. And the logic is simple, no Adblocker will block you from clicking something intentionally and it (the link) opening in another window/tab.
The problem is the new window contains your clicked Url, while the original window/tab "Refreshes" (i.e. redirects) to another url.
Advertising companies seem to use this trick to bypass adblocking software.
Just ditch Chrome and use Firefox. Firefox already have built-in mouse-click popups. I think all addons like Adguard or Adblock can not disable mouse-click popups. If you use Firefox, these are the steps:
Type about:config in the browser's address bar and hit the enter key.
First time users need to confirm that they be careful on the next page.
Type or paste dom.popup_allowed_events into the search field.
The value of the preference highlights all events that are allowed to spawn popups.
Edit the value to remove some or all of the items here.
Why not just use a browser extension such as AdBlock?

My go-to is right click and open in new tab. onClick events only happen with a left click. It's cumbersome but it still ends up being less work than closing the pop-up and whatever annoying prompts it may have.
I do not there's a practical solution for this.
Moreover, I think some of the answers here are missing the specific case in OP, where clicking anywhere on the page will cause the pop up to happen, not just clicking on links. According to this, neither right-clicking then choosing "open", nor noticing and blocking the target URL will help. I do not know of an add blocker that helps here either, because it's not trivial to meaningfully filter a click event that is taking place on the whole page object.
Only the solution provided by #Monkey would work, at the drawback of possibly breaking other things.
Is there a way I can maximize a currently minimized window from Javascript? Here's my situation:
I have a series of links that all target the same external window (e.g. "MyNewWindow"). When I click a link, a new window pops up. If I click another link, the page pops up in the same window as expected. If I minimize the "MyNewWindow" popup, I'd like to be able to click another link and have that window maximize.
My approach was to put something on the onLoad part of the body so that when the page is refreshed it will automatically "maximize" if it is minimized. Note: Using window.MoveTo() and window.resizeTo() doesnt seem to do the trick (the window stays minimized).
Thanks!
For all of you know-it-alls, there are perfectly good reasons to want to know how to do this. Here's the reason I needed this:
I'm deploying SCORM modules to a variety of Learning Management Systems (LMSs)
One LMS that a client is using launches the module in a small (600x400) window, with the user controls to maximize or resize said window DISABLED
The client doesn't know how to change this launch behavior
My only option is to try to maximize via javascript, because the idiots who made the LMS took away the user's ability to manage their own windows.
window.moveTo(0, 0);
window.resizeTo(screen.availWidth, screen.availHeight);
This may not work in IE depending on the security zone your page is falling under, and it may not work in Chrome at all. But for a corporate environment in an intranet, it has a good chance of working.
Don't do this, you are not allowed to do this by most modern browsers for a reason.
In a tabbed environment you're not messing with only the window you may have created, but all of my tabs, that's unacceptable. It's the user's computer, user's browser, it's the user who chose to go to your site...let them size the window the way they want it, doing anything else breaks their experience...and their trust in your site.
The behavior you're looking to emulate is what your run-of-the-mill malware does...re-think your approach, please. For example focusing that window is appropriate for what you want, let the default behavior of the browser take over from there, like this:
var thatWindow = window.open(url, "linkWindow");
thatWindow.focus();
try to use window.open(url,fullscreen=yes);
if you out fullscreen=yes than while clinking on link automatically
