How to open a file with print dialogue box using JavaScript

How to open a file with print dialogue box using JavaScript - javascript

I want to open one word document using JavaScript as well as open print dialogue box for that opened document window.
Here is my code.
window.open('http://www.tizaq.com');
window.print();
It works, but the print dialogue gets opened for the current window, not the newly opened window. How do I do it?

Call print on the new window rather than the old:
var wnd = window.open('http://stackoverflow.com');
wnd.print();
I don't like your odds, though, of it not falling afoul of browser security. :-) The "external" window object may well not support print (window objects come in two types, the "external" type that other windows have access to, and the "internal" type that references itself, which has more permissions, etc.) At the least, you'll probably have to wait for the load event, but I best in general it's going to be tricky.
It seems to work for documents with the same origin, so the Same Origin Policy is a factor. That example crashes in IE6 (literally crashes the browser), but works for me in IE7 on Windows, and Chrome and Firefox 3.6 on Linux (and not in Opera 11 on Linux). Probably wouldn't hurt to put a delay / yield in there, e.g.:
var wnd = window.open(your_path_here);
setTimeout(function() {
wnd.print();
}, 0);
You said "word document" in your question, but your example looks like a website. I have no idea whether this would work if you were opening a Microsoft Word document by loading it into a browser window.

Well, Better way
var my_window = window.open("", "mywindow1", "status=1,width=350,height=150");
my_window.document.write("<scr" + "ipt>window.location.href='http://stackoverflow.com';window.print();</scr" + "ipt>");
try Like this or better to make another page using iframe for print

Closing Browser Tab not working in Chrome

I am trying to close the tab using script, but it's not working.
<button type="button" class="btn btn-primary" id="btnClose">Close</button>
$('#btnClose').click(function() {
var newWindow = window.open('https://localhost:44384/MasterUpdate/Index/1', '_self', '');
window.close(newWindow);
});
The URL I am using is for testing purposes only. In my code I manually manage it using this:
string referer = Request.Headers["Referer"].ToString();
ViewBag.GetCurrentURL = referer;
I have tried so many ways but they didn't work for me.
javascript:window.open('','_self').close();
window.top.close();
window.close();

As Rory pointed out, there are few conditions when window.close() works.
Below is the excerpt from this link:
close browser tab/window
Note that window.close() will only work under the following conditions:
On all modern browsers, the web page to be closed must be the first in that window/tab's session history. That is, if you hit the Back button on the browser, you will not go to a previous page in that window/tab because there is none.
You can easily accomplish that by opening that page either with JavaScript, for example, by using window.open(), or through a link that has a target="_blank" attribute. You can find example code for the former in the demo below, and the latter in the article on opening links in a new window or tab.
If you only test your code in an old browser (eg, old versions of Chrome or Firefox, or any version of Internet Explorer), you will end up with the mistaken impression that it works fine even if the above conditions are not true. Newer browser versions impose these restrictions for security (and other) reasons.
Modern browsers will also resist your attempt to trick them into thinking that an existing window/tab was opened with JavaScript when it was not. Some older versions fell for such trickery, but these methods should no longer work in the current versions of Chrome and Firefox.
Also, for tab/window must be opened via window.open() for window.close(0 to work.

If you will to close the tab you've created with window.open you just have to store the new tab into variable and then use .close() method of this variable when you want to close it.
Short example:
const newWindow = window.open('');
setTimeout(() => newWindow.close(), 1000);
This example shows how to create new window and then close it after 1 sec.
If you want to manualy close the tab, just call newWindow.close() function wherever you want.

closing browser window where angular application upon a button click [duplicate]

The issue is that when I invoke window.close() or self.close() it doesn't close the window. Now there seems to be a belief that in Chrome you can't close by script any window that is not script created. That is patently false but regardless it is supposed to still do it, even if it requires to pop up an alert to confirm. These are not happening.
So does anyone have real, functional and proven method of closing a window using something like javascript:window.close() or javascript:self.close() that actually does what is expected and something that happens just fine in every browser that is NOT Chrome based? Any suggestions would be greatly appreciated and I am looking for Javascript specific solution, nothing JQuery or third party implementation.
Update: While much of what has been suggested has serious limitations and usability issues, the latest suggestion (specific to TamperMonkey) using // #grant window.close in the script header will often do the trick even on those tabs that normally can't handle the close method. While not entirely ideal and doesn't generalized to every case, it is a good solution in my case.

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.
From the latest working spec for window.close():
The close() method on Window objects should, if all the following conditions are met, close the browsing context A:
The corresponding browsing context A is script-closable.
The browsing context of the incumbent script is familiar with the browsing context A.
The browsing context of the incumbent script is allowed to navigate the browsing context A.
A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.
This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.
Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:
This method is only allowed to be called for windows that were opened by a script using the window.open method.
If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.
The long-term solution:
The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.
However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.
The hacky workarounds:
Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:
open(location, '_self').close();
This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.
However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit #grant and plain window.close(). EG:
// ==UserScript==
// #name window.close demo
// #include http://YOUR_SERVER.COM/YOUR_PATH/*
// #grant GM_addStyle
// ==/UserScript==
setTimeout (window.close, 5000);
Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.
Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.
You can open up about:config and set
allow_scripts_to_close_windows to true.
If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.
There currently is no equivalent setting for Chrome.

Chrome Fixed the security issues on version 36.0.1985.125
Chrome 36.0.1985.125 WEDNESDAY, JULY 16, 2014
Release note
From my observation, this update fixed the issue on using window.close() to close the popup window. You will see this in the console when it fail, "Scripts may close only the windows that were opened by it.". That means The hacky workarounds (Brock Adams's answer) may not work in the latest release.
So, in the previous Chrome released builds, the below code block may worked but not with this update.
window.open('', '_self', '');
window.close();
For this update, you have to update your code accordingly to close the popup window. One of the solution is to grab the popup window id and use
chrome.windows.remove(integer windowId, function callback)
method to remove it. Chrome extension windows API can be found at chrome.windows.
Actually my chrome extension MarkView was facing this issue and I had to update my code to make it work for this Chrome Update. By the way, MarkView is tool to read and write Awesome Markdown Files, it provides features including Content Outline, Sortable Tables and code block syntax highlight with line number.
I also created this post, any comments are welcome.

In tampermonkey now you can use
// #grant window.close
And then just simply call
window.close();

Requrements for this to work:
You have to open the window/tab from a window launcher to get a javascript handle to have it work, as it does not always work on a tab that was not opened via a window-launcher script. This test page shows you how:
http://browserstrangeness.bitbucket.io/window_close_tester.htm
If you don't see it working from my launcher, posting your browser, your device and versions are necessary. Browsers of different versions act differently on different devices. (Such as Firefox and Chrome on iPads which are NOT what they say they are. They are Safari with a different skin!)
So it is important to say for example 'I am using Safari 10.14 on an iPad using iOs 14.5' so I (or some other helpful individual here at stackoverflow) can research it for you and post results to help other users. Thanks in advance for doing that. If you use the launcher and it works on my example for you, then it works.
I am using the method posted by Brock Adams and it even works in Firefox, if it's user initiated by being launched by button or link from another window.
open(location, '_self').close();
I am calling it from a button press so it is user initiated, and it is still working fine using Chrome 90, Internet Explorer 11, Edge, Safari 7-10 and ALSO Firefox 35 & 88. I tested using version 8.1 & 10 of Windows and Mac OS X 10.6, 10.9 & 10.10 & 10.14 if that is different.
Self-Closing Window Code (on the page that closes itself)
The complete code to be used on the user-opened window that can close itself:
window_to_close.htm
JavaScript:
function quitBox(cmd)
{
if (cmd=='quit')
{
open(location, '_self').close();
}
return false;
}
HTML:
<input type="button" name="Quit" id="Quit" value="Quit" onclick="return quitBox('quit');" />
Here is that test page again with a working example: (Now tested in Chrome 90.0 and Firefox 88.0 -- both on Windows 10 and Mac 10.14 Mojave)
http://browserstrangeness.bitbucket.io/window_close_tester.htm
Window Opener Code (on a page that opens the above page)
To make this work, security-imposed cross browser compatibility requires that the window that is to be closed must have already been opened by the user clicking a button within the same site domain.
For example, the window that uses the method above to close itself, can be opened from a page using this code (code provided from my example page linked above):
window_close_tester.htm
JavaScript:
function open_a_window()
{
window.open("window_to_close.htm");
return false;
}
HTML:
<input type="button" onclick="return open_a_window();" value="Open New Window/Tab" />

Many people are still trying to find a way to close the Chrome browser using javascript. The following method only works when you use Chrome as APP launcher - kiosk for example!
I have tested the following:
I'm using the following extension: Close Kiosk
I'm following the usage instructions and it seems to work just fine (make sure you clear the cache while doing the tests). The javascript I use is (attached to click event):
window.location.href = '/closekiosk';
I hope that helps somebody, as it's the only working solution I have found.
Note: It seems the extension runs in background and adds a Chrome tray icon. It has the following option checked: "Let Chrome run in background" (or similar text). You may need to play with it, until it work for you. I unchecked it and now it works just fine!

Despite thinking it is "patently false", what you say "seems to be a belief" is actually correct. The Mozilla documentation for window.close says
This method is only allowed to be called for windows that were opened by a script using the window.open method. If the window was not opened by a script, the following error appears in the JavaScript Console: Scripts may not close windows that were not opened by script
You say that it is "supposed to still do it" but I don't think you'll find any reference which supports that, maybe you've misremembered something?

I found a new way that works for me perfetly
var win = window.open("about:blank", "_self");
win.close();

The below code worked for me -
window.open('location', '_self', '');
window.close();
Tested on Chrome 43.0.2357.81

This might be old, but let's answer it.
I use top.close() to close a tab. window.close() or other open...close didn't work for me.

In my case, the page needed to close, but may have been opened by a link and thus window.close would fail.
The solution I chose is to issue the window.close, followed by a window.setTimeout that redirects to a different page.
That way, if window.close succeeds, execution on that page stops, but if it fails, in a second, it will redirect to a different page.
window.close();
window.setTimeout(function(){location.href = '/some-page.php';},1000);

I wanted to share my "solution" with this issue. It seems like most of us are trying to close a browser window in a standard browser session, where a user is visiting some website or another, after they've visited other websites, and before they'll visit some more.
However, my situation is that I am building a web app for a device that will essentially be the only thing the device does. You boot it up, it launches Chrome and navigates to our app. It's not even connected to the internet, any servers it talks to are on our local Docker containers. The user needs a way to close the app (aka close Chrome) so they can access the terminal to perform system updates.
So it boots up, launches Chrome in kiosk mode, at the correct address already. This happens to easily satisfy the second option in the spec:
A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a top-level browsing context whose session history contains only one Document.
So simply calling window.close() from my kiosk app just works!

If you can't close windows that aren't opened by the script, then you can destroy your page using this code:
document.getElementsByTagName ('html') [0] .remove ();

For those that are using an anchor tag to open the child window, this article describes a workaround for this issue.
My understanding is that in new versions of Chrome, the rel attribute is set to noopener by default for anchor tags with target _blank. So by setting it to opener you have the old behaviour back.
Please be aware that this was introduced to avoid tab-napping attacks.

Only if you open a new window using window.open() will the new window be able to close using code as I have mentioned above. This works perfectly for me :) Note : Never use href to open the page in a new tab. Window.close() does not work with "href" . Use window.open() instead.

You can also try to use my code below. This will also help you to redirect your parent window:
Parent:
<script language="javascript">
function open_a_window()
{
var w = 200;
var h = 200;
var left = Number((screen.width/2)-(w/2));
var tops = Number((screen.height/2)-(h/2));
window.open("window_to_close.html", '', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+tops+', left='+left);
return false;
}
// opener:
window.onmessage = function (e) {
if (e.data === 'location') {
window.location.replace('https://www.google.com');
}
};
</script>
<input type="button" onclick="return open_a_window();" value="Open New Window/Tab" />
Popup:
<!DOCTYPE html>
<html>
<body onload="quitBox('quit');">
<h1>The window closer:</h1>
<input type="button" onclick="return quitBox('quit');" value="Close This Window/Tab" />
<script language="javascript">
function quitBox(cmd)
{
if (cmd=='quit')
{
window.opener.postMessage('location', '*');
window.open(location, '_self').close();
}
return false;
}
</script>
</body>
</html>

For TamperMonkey:
#grant window.close
Ref: https://www.tampermonkey.net/documentation.php#_grant

Try something like this onclick="return self.close()"

self.close() not working...Is there any work-around for that? [duplicate]

If you don't see it working from my launcher, posting your browser, your device and versions are necessary. Browsers of different versions act differently on different devices. (Such as Firefox and Chrome on iPads which are NOT what they say they are. They are Safari with a different skin!)
So it is important to say for example 'I am using Safari 10.14 on an iPad using iOs 14.5' so I (or some other helpful individual here at stackoverflow) can research it for you and post results to help other users. Thanks in advance for doing that. If you use the launcher and it works on my example for you, then it works.
I am using the method posted by Brock Adams and it even works in Firefox, if it's user initiated by being launched by button or link from another window.
open(location, '_self').close();
I am calling it from a button press so it is user initiated, and it is still working fine using Chrome 90, Internet Explorer 11, Edge, Safari 7-10 and ALSO Firefox 35 & 88. I tested using version 8.1 & 10 of Windows and Mac OS X 10.6, 10.9 & 10.10 & 10.14 if that is different.
Self-Closing Window Code (on the page that closes itself)
The complete code to be used on the user-opened window that can close itself:
window_to_close.htm
JavaScript:
function quitBox(cmd)
{
if (cmd=='quit')
{
open(location, '_self').close();
}
return false;
}
HTML:
<input type="button" name="Quit" id="Quit" value="Quit" onclick="return quitBox('quit');" />
Here is that test page again with a working example: (Now tested in Chrome 90.0 and Firefox 88.0 -- both on Windows 10 and Mac 10.14 Mojave)
http://browserstrangeness.bitbucket.io/window_close_tester.htm
Window Opener Code (on a page that opens the above page)
To make this work, security-imposed cross browser compatibility requires that the window that is to be closed must have already been opened by the user clicking a button within the same site domain.
For example, the window that uses the method above to close itself, can be opened from a page using this code (code provided from my example page linked above):
window_close_tester.htm
JavaScript:
function open_a_window()
{
window.open("window_to_close.htm");
return false;
}
HTML:
<input type="button" onclick="return open_a_window();" value="Open New Window/Tab" />

Many people are still trying to find a way to close the Chrome browser using javascript. The following method only works when you use Chrome as APP launcher - kiosk for example!
I have tested the following:
I'm using the following extension: Close Kiosk
I'm following the usage instructions and it seems to work just fine (make sure you clear the cache while doing the tests). The javascript I use is (attached to click event):
window.location.href = '/closekiosk';
I hope that helps somebody, as it's the only working solution I have found.
Note: It seems the extension runs in background and adds a Chrome tray icon. It has the following option checked: "Let Chrome run in background" (or similar text). You may need to play with it, until it work for you. I unchecked it and now it works just fine!

Despite thinking it is "patently false", what you say "seems to be a belief" is actually correct. The Mozilla documentation for window.close says
This method is only allowed to be called for windows that were opened by a script using the window.open method. If the window was not opened by a script, the following error appears in the JavaScript Console: Scripts may not close windows that were not opened by script
You say that it is "supposed to still do it" but I don't think you'll find any reference which supports that, maybe you've misremembered something?

I found a new way that works for me perfetly
var win = window.open("about:blank", "_self");
win.close();

The below code worked for me -
window.open('location', '_self', '');
window.close();
Tested on Chrome 43.0.2357.81

This might be old, but let's answer it.
I use top.close() to close a tab. window.close() or other open...close didn't work for me.

In my case, the page needed to close, but may have been opened by a link and thus window.close would fail.
The solution I chose is to issue the window.close, followed by a window.setTimeout that redirects to a different page.
That way, if window.close succeeds, execution on that page stops, but if it fails, in a second, it will redirect to a different page.
window.close();
window.setTimeout(function(){location.href = '/some-page.php';},1000);

I wanted to share my "solution" with this issue. It seems like most of us are trying to close a browser window in a standard browser session, where a user is visiting some website or another, after they've visited other websites, and before they'll visit some more.
However, my situation is that I am building a web app for a device that will essentially be the only thing the device does. You boot it up, it launches Chrome and navigates to our app. It's not even connected to the internet, any servers it talks to are on our local Docker containers. The user needs a way to close the app (aka close Chrome) so they can access the terminal to perform system updates.
So it boots up, launches Chrome in kiosk mode, at the correct address already. This happens to easily satisfy the second option in the spec:
A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a top-level browsing context whose session history contains only one Document.
So simply calling window.close() from my kiosk app just works!

If you can't close windows that aren't opened by the script, then you can destroy your page using this code:
document.getElementsByTagName ('html') [0] .remove ();

For those that are using an anchor tag to open the child window, this article describes a workaround for this issue.
My understanding is that in new versions of Chrome, the rel attribute is set to noopener by default for anchor tags with target _blank. So by setting it to opener you have the old behaviour back.
Please be aware that this was introduced to avoid tab-napping attacks.

Only if you open a new window using window.open() will the new window be able to close using code as I have mentioned above. This works perfectly for me :) Note : Never use href to open the page in a new tab. Window.close() does not work with "href" . Use window.open() instead.

You can also try to use my code below. This will also help you to redirect your parent window:
Parent:
<script language="javascript">
function open_a_window()
{
var w = 200;
var h = 200;
var left = Number((screen.width/2)-(w/2));
var tops = Number((screen.height/2)-(h/2));
window.open("window_to_close.html", '', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+tops+', left='+left);
return false;
}
// opener:
window.onmessage = function (e) {
if (e.data === 'location') {
window.location.replace('https://www.google.com');
}
};
</script>
<input type="button" onclick="return open_a_window();" value="Open New Window/Tab" />
Popup:
<!DOCTYPE html>
<html>
<body onload="quitBox('quit');">
<h1>The window closer:</h1>
<input type="button" onclick="return quitBox('quit');" value="Close This Window/Tab" />
<script language="javascript">
function quitBox(cmd)
{
if (cmd=='quit')
{
window.opener.postMessage('location', '*');
window.open(location, '_self').close();
}
return false;
}
</script>
</body>
</html>

For TamperMonkey:
#grant window.close
Ref: https://www.tampermonkey.net/documentation.php#_grant

Try something like this onclick="return self.close()"

Safari and window.open() -- how to use it and not get focus?

My order entry web site is being enhanced to have a Master / Child window architecture. The Child windows would be used for "by the way..." searches and the Master window is where editing occurs. Periodically the Master window wants to tell things to the Child windows. If it has a handle to the child, such as that from window.open(), then this is easy.
Because the user might refresh the Master window (F5) the page must recover its list of children. I don't know of a way of doing this apart from going through a list of likely child window names using window.open(). Tests of this idea on my computer running Windows, with the Chrome / Firefox / MSIE browsers, all work OK.
However, I don't get good Safari results. When run on a variety of Mac OS / Safari versions calling window.open() always also brings that window to the foreground. To me this is deal-breaking behavior. Running window.open() then window.blur() isn't acceptable due to the flash display of the undesired window.
Question: Is there a way of calling window.open() (and not window.blur()) while always suppressing the "bring to foreground" behavior?
Question: Are there ways of getting a window handle w/o using window.open()?
Thanks,
Jerome.

window.opener would be the answer for your question. But window.opener is not supported by IE.
something like below would help.
if ($.browser.safari)
std = window.opener("", "childwindowname");
else
std = window.open("", "childwindowname");
