New window opens when button is clicked but not when using .onclick()

I am using software that creates all the HTML/XML so I don't have this and I have created a button to open a form in a new window. When I physically click on this button, everything works. However when I run the code onload, I get a message saying that the page is blocked and I need to remove any popup blocker
var button = getElement("GUID_of_Button");
button.click();
This code works if I set to open the form in the same window as a tooltip but not as a new window. I tried on Chrome, Firefox and IE with same results. (no console error)
Not sure if this helps (get this when I inspect element)
<input name="buttoncontrol0F09F8F7" id="ID_buttoncontrol0F09F8F7" value="Click here" type="submit" title="Click here" class="Button_Standard" style="cursor: pointer;">==$0
Naturally I can remove any blockers but as this is for the whole office, I can't ask everyone to do this just so I can get this to work. Any advise is appreciated.

This is a feature of modern browsers that restricts the opening of new windows to user-initiated actions.
This is important as it mitigate security risks and gets rid of the most obnoxious advertising.
Unless you can get everyone to change their browser settings, you won't have a new window opened automatically.
Depending on the data you need to display, you could consider alternative to new windows such as modals / pop-ins. Take a look for example at Bootstrap's modal.

Popup windows are generally used for advertisement and these windows will be opened without permission of user. Inorder to prevent this, most of the web browsers comes with popup blockers which should be explicitly configured by user if they want to automatically open something in a new window.
If you want to use this featue, you'll have to ask users to configure popup blockers in their web browser.

Closing a tab without closing the window

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.

How to allow popups when url loads if it is NOT a physical click by the user in js

I want to allow popups when site loads and if the root cause of an event is NOT a physical click by the user, then it's getting blocked. any help
My code:
$("#buttonBtn").on('click',function(){
openpopup('temp'+id)
});
$("#buttonBtn").trigger('click');
Thanks in advance

With this, if you explicitly click, popup appears. If user comes to this button via keyboard and press Enter or something, I guess this would not be triggered.
$("#buttonBtn").click(function(e){
e.preventDefault();
// some job you will do if clicked, for example, open popup
});
Great example here

You can generally open popups by using window.open. However, most browsers have built-in popup blocker where the user will be notified about a popup and will be asked if he really wants to show it.
The MDN has an informative article about window.open. It also gives some information about popup blockers:
How can I tell when my window was blocked by a popup blocker?
With the
built-in popup blockers of Mozilla/Firefox and Internet Explorer 6
SP2, you have to check the return value of window.open(): it will be
null if the window wasn't allowed to open. However, for most other
popup blockers, there is no reliable way.

Close Browser window while unloading

I have MyPage.aspx html page (generated using ASP.Net). When user tries to navigate away from this page, I need to close the window – user should not be able to go back or navigate to another page.
When I used window.close() inside window.onbeforeunload event, it asks for a confirmation to the user. “The webpage you are viewing is trying to close the window. Do you want to close the window?” On clicking “No” the user can escape the close attempt. Is there any way to forcefully close the window without giving an option to the user?
Reference:
How can I close a browser window without receiving the "Do you want to close this window" prompt?
Html javascript to open new window and close current window
"Unknown Exception" when cancelling page unload with "location.href"
Display confirmation popup with JavaScript upon clicking on a link

You can "trick" the browser like this:
window.onbeforeunload = function() {
window.open('', '_self', '');
window.close();
}
It seems to work in chrome/safari/ie/ff: http://jsbin.com/olijig/1
Firefox seems stubborn, but there might be another way to do the same in FF.
I should probably say that this technique is in no way standard and I don’t recommend it at all, and this code might break in many browsers besides firefox.
UPDATE
It actually works in Firefox too (latest version), but not older versions (I tried 3.6.1). You need to do some more testing to confirm the browser compatibility.

No, you can't. The user must be always capable of controlling whatever happens in his browser.

I'm not positive about this, but I believe if you have a window open another window, the parent window can close that child window. Would it be practical to have a landing page that opens your app in a separate window that could then close the window through javascript? Someone can probably elaborate more, as I haven't done this myself.

Keep Chrome extension popup open while navigating to a new page

I'm developing a Google Chrome extension with a popup (it's a browser action), and it changes the location of the page, which makes the popup disappear. How can I make it stay between page reloads?

You can't. browserAction popups are closed on any activity outside of the popup. You could potentially use Desktop Notifications though.

You'll need to use Background Page, and pull information from it every time you load the popup. Background pages run whether or your extension is currently being used or not.
Not sure if this helps, but from the FAQ:
Can extensions keep popups open after the user clicks away from them?
No, popups automatically close when the user focuses on some portion of the browser outside of the popup. There is no way to keep the popup open after the user has clicked away.

I had to implement a workaround for this as well. In my case, I was trying to use auth0's loginWithPopup. When the popup closed, it returned focus to the chrome window instead of the extension which caused the extension to close before authorization fully completed. I worked around it by opening a new window which acts as a barrier of sorts to prevent chrome's focus from going back to the window the extension was opened from. Anyway, just wanted to put it out there in case it helps someone in the future.
