How to open a mailto: link from a Chrome Extension? - javascript

I have a URL shortening Chrome extension called Shrtr. Right now, it allows users to copy the shortened URL to clipboard, but in the next version, I've added the ability to email the shortened URL, using a mailto: link (i.e. mailto:?subject=<original page title>&body=<short URL>).
The problem is, you cannot just assign document.location.href = 'mailto...'; from an extension. The following 2 methods worked for me, but with both, I end up with an open blank tab in the browser:
Method 1: window.open
var wnd = window.open(emailUrl);
setTimeOut(function() {
wnd.close();
}, 500);
Notice the need to wait before closing the window. This works (i.e. mail client new message dialog appears, pre-populated), but the new tab remains open.
Method 2: using chrome.tabs
chrome.tabs.create({ url: emailUrl }, function(tab) {
setTimeOut(function() {
chrome.tabs.remove(tab.id);
}, 500);
});
Again, works - but tab remains open. Any ideas?

var emailUrl = "mailto:blah#blah.com";
chrome.tabs.update({
url: emailUrl
});

I realize this is an old question, but I myself had the same issue, and I figured out how to solve the problem so I thought I would share.
The issue stems from the fact that (I believe) you are calling the below code from your extension popup page.
chrome.tabs.create({ url: emailUrl }, function(tab) {
setTimeout(function() {
chrome.tabs.remove(tab.id);
}, 500);
});
The problem with this is that as soon as a new tab is created, the popup page dies and the callback code is never executed.
We can remedy this by moving that code into a function within the background page whose lifetime is not tied to the popup page:
function sendEmail() {
var emailUrl = "mailto:blah#blah.com";
chrome.tabs.create({ url: emailUrl }, function(tab) {
setTimeout(function() {
chrome.tabs.remove(tab.id);
}, 500);
});
}
and calling it via chrome.extension.getBackgroundPage().sendEmail() from your popup page.
Using the above method, the default email client will be opened, and the new tab will be automatically closed after 500 milliseconds.

wouldnt u need a close statement like this
close

or even something like this
//keep a handle to the window you open.
var newWin = window.open('my window', 'http://.../');
...
//some point later in the code
newWin.close();

I have solved the problem. Please check if it fits your solution space.
I have used the following code to open a mailto client in chrome extension.
$('.email').click(function(){
var hrefString = $(this).attr('href');
var myWindow = window.open(hrefString, "Opening mail client", "width=200, height=100");
myWindow.document.write("<p>Opening mail client.Please wait!!</p>");
setTimeout(function(){ myWindow.close() }, 2000);
});
where the element was :
<a style="padding: 0 0 0 5px;" href="mailto:abc#xyz.com" class="email">
This worked for me.
Hope it will help others.

Window.open() not working on google chrome

Good day.
In my vuejs application i am trying to open a new tab trough window.open() but whenever i do that the a new tab opens and immediately closes before loading anything at all. Window.open() works just fine on Firefox and window.location.replace also works normally.
Why window.open() ain't working?
openWindow(info) {
window.open('http://10.100.100.100:9999/window?someInfo=' + info);
},
PS: I also tried the following code just to see what happens and it worked just fine.
openWindow(info) {
window.open("http://www.google.com");
},
Per https://developer.mozilla.org/en-US/docs/Web/API/Window/open
It appears you need the second param.
window.open(url, windowName, [windowFeatures]);
openWindow(info) {
window.open('http://10.100.100.100:9999/window?someInfo=' + info, '_blank');
},
I was lodged here on search.
I faced such issue only on mobile chrome.
The two param didn't work for me. So i used 3 params.
openWindow(info) {
window.open('http://10.100.100.100:9999/window?someInfo=' + info, '_blank', 'popup=1');
}
or
openWindow(info) {
window.open('http://10.100.100.100:9999/window?someInfo=' + info, '_blank', '');
}

How can I open a link in new tab after ajax call? [duplicate]

I'm trying to open a URL in a new tab, as opposed to a popup window.
I've seen related questions where the responses would look something like:
window.open(url,'_blank');
window.open(url);
But none of them worked for me, the browser still tried to open a popup window.
This is a trick,
function openInNewTab(url) {
window.open(url, '_blank').focus();
}
// Or just
window.open(url, '_blank').focus();
In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.
<div onclick="openInNewTab('www.test.com');">Something To Click On</div>
Reference: Open a URL in a new tab using JavaScript
Nothing an author can do can choose to open in a new tab instead of a new window; it is a user preference. (Note that the default user preference in most browsers is for new tabs, so a trivial test on a browser where that preference hasn't been changed will not demonstrate this.)
CSS3 proposed target-new, but the specification was abandoned.
The reverse is not true; by specifying certain window features for the window in the third argument of window.open(), you can trigger a new window when the preference is for tabs.
window.open() will not open in a new tab if it is not happening on the actual click event. In the example given the URL is being opened on the actual click event. This will work provided the user has appropriate settings in the browser.
<a class="link">Link</a>
<script type="text/javascript">
$("a.link").on("click",function(){
window.open('www.yourdomain.com','_blank');
});
</script>
Similarly, if you are trying to do an Ajax call within the click function and want to open a window on success, ensure you are doing the Ajax call with the async : false option set.
This creates a virtual a element, gives it target="_blank", so it opens in a new tab, gives it the proper URL href and then clicks it.
function openInNewTab(href) {
Object.assign(document.createElement('a'), {
target: '_blank',
rel: 'noopener noreferrer',
href: href,
}).click();
}
And then you can use it like:
openInNewTab("https://google.com");
Important note:
This must be called during the so-called 'trusted event' callback—e.g., during the click event (not necessary in a callback function directly, but during a click action). Otherwise opening a new page will be blocked by the browser.
If you call it manually at some random moment (e.g., inside an interval or after server response), it might be blocked by the browser (which makes sense as it'd be a security risk and might lead to poor user experience).
Browsers have different behaviors for how they handle window.open
You cannot expect the behavior to be the same across all browsers. window.open doesn't reliably open pop-ups on a new tab across browsers, and it also depends on the user's preferences.
On Internet Explorer (11), for example, users can choose to open popups in a new window or a new tab, you cannot force Internet Explorer 11 to open popups in a certain way through window.open, as alluded to in Quentin's answer.
As for Firefox (29), the behavior for window.open(url, '_blank') depends on the browser's tab preferences, though you can still force it to open URLs in a popup window by specifying a width and height (see the "Chrome" section below).
Internet Explorer (11)
You can set Internet Explorer to open pop-ups in a new window:
After doing that, try running window.open(url) and window.open(url, '_blank').
Observe that the pages open in a new window, not a new tab.
Firefox (29)
You can also set the tab preference to open new windows, and see the same results.
Chrome
It looks like Chrome (version 34) does not have any settings for choosing to open popups in a new window or a new tab. Although, some ways to do it (editing the registry) are discussed in this question.
In Chrome and Firefox, specifying a width and height will force a popup (as mentioned in the answers here), even when a user has set Firefox to open new windows in a new tab
let url = 'https://stackoverflow.com'
window.open(url, '', 'width=400, height=400')
However, in Internet Explorer 11 the same code will always open a link in a new tab if tabs is chosen in the browser preferences, specifying a width and height will not force a new window popup.
In Chrome, it seems window.open opens a new tab when it is used in an onclick event, and a new window when it is used from the browser console (as noted by other people), and pop-ups open when a width and height are specified.
Additional reading: window.open documentation.
If you use window.open(url, '_blank'), it will be blocked (popup blocker) on Chrome.
Try this:
//With JQuery
$('#myButton').click(function () {
var redirectWindow = window.open('http://google.com', '_blank');
redirectWindow.location;
});
With pure JavaScript,
document.querySelector('#myButton').onclick = function() {
var redirectWindow = window.open('http://google.com', '_blank');
redirectWindow.location;
};
To elaborate Steven Spielberg's answer, I did this in such a case:
$('a').click(function() {
$(this).attr('target', '_blank');
});
This way, just before the browser will follow the link I'm setting the target attribute, so it will make the link open in a new tab or window (depends on user's settings).
One line example in jQuery:
$('a').attr('target', '_blank').get(0).click();
// The `.get(0)` must be there to return the actual DOM element.
// Doing `.click()` on the jQuery object for it did not work.
This can also be accomplished just using native browser DOM APIs as well:
document.querySelector('a').setAttribute('target', '_blank');
document.querySelector('a').click();
I use the following and it works very well!
window.open(url, '_blank').focus();
I think that you can't control this. If the user had setup their browser to open links in a new window, you can't force this to open links in a new tab.
JavaScript open in a new window, not tab
An interesting fact is that the new tab can not be opened if the action is not invoked by the user (clicking a button or something) or if it is asynchronous, for example, this will not open in new tab:
$.ajax({
url: "url",
type: "POST",
success: function() {
window.open('url', '_blank');
}
});
But this may open in a new tab, depending on browser settings:
$.ajax({
url: "url",
type: "POST",
async: false,
success: function() {
window.open('url', '_blank');
}
});
Whether to open the URL in a new tab or a new window, is actually controlled by the user's browser preferences. There is no way to override it in JavaScript.
window.open() behaves differently depending on how it is being used. If it is called as a direct result of a user action, let us say a button click, it should work fine and open a new tab (or window):
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open a new tab
const tab = window.open('https://attacomsian.com', '_blank');
});
However, if you try to open a new tab from an AJAX request callback, the browser will block it as it was not a direct user action.
To bypass the popup blocker and open a new tab from a callback, here is a little hack:
const button = document.querySelector('#openTab');
// add click event listener
button.addEventListener('click', () => {
// open an empty window
const tab = window.open('about:blank');
// make an API call
fetch('/api/validate')
.then(res => res.json())
.then(json => {
// TODO: do something with JSON response
// update the actual URL
tab.location = 'https://attacomsian.com';
tab.focus();
})
.catch(err => {
// close the empty window
tab.close();
});
});
Just omitting the strWindowFeatures parameters will open a new tab, unless the browser setting overrides it (browser settings trumps JavaScript).
New window
var myWin = window.open(strUrl, strWindowName, [strWindowFeatures]);
New tab
var myWin = window.open(strUrl, strWindowName);
-- or --
var myWin = window.open(strUrl);
This has nothing to do with browser settings if you are trying to open a new tab from a custom function.
In this page, open a JavaScript console and type:
document.getElementById("nav-questions").setAttribute("target", "_blank");
document.getElementById("nav-questions").click();
And it will try to open a popup regardless of your settings, because the 'click' comes from a custom action.
In order to behave like an actual 'mouse click' on a link, you need to follow spirinvladimir's advice and really create it:
document.getElementById("nav-questions").setAttribute("target", "_blank");
document.getElementById("nav-questions").dispatchEvent((function(e){
e.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
false, false, false, false, 0, null);
return e
}(document.createEvent('MouseEvents'))));
Here is a complete example (do not try it on jsFiddle or similar online editors, as it will not let you redirect to external pages from there):
<!DOCTYPE html>
<html>
<head>
<style>
#firing_div {
margin-top: 15px;
width: 250px;
border: 1px solid blue;
text-align: center;
}
</style>
</head>
<body>
<a id="my_link" href="http://www.google.com"> Go to Google </a>
<div id="firing_div"> Click me to trigger custom click </div>
</body>
<script>
function fire_custom_click() {
alert("firing click!");
document.getElementById("my_link").dispatchEvent((function(e){
e.initMouseEvent("click", true, true, window, /* type, canBubble, cancelable, view */
0, 0, 0, 0, 0, /* detail, screenX, screenY, clientX, clientY */
false, false, false, false, /* ctrlKey, altKey, shiftKey, metaKey */
0, null); /* button, relatedTarget */
return e
}(document.createEvent('MouseEvents'))));
}
document.getElementById("firing_div").onclick = fire_custom_click;
</script>
</html>
function openTab(url) {
const link = document.createElement('a');
link.href = url;
link.target = '_blank';
document.body.appendChild(link);
link.click();
link.remove();
}
(function(a) {
document.body.appendChild(a);
a.setAttribute('href', location.href);
a.dispatchEvent((function(e) {
e.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, false, 0, null);
return e
}(document.createEvent('MouseEvents'))))
}(document.createElement('a')))
You can use a trick with form:
$(function () {
$('#btn').click(function () {
openNewTab("http://stackoverflow.com")
return false;
});
});
function openNewTab(link) {
var frm = $('<form method="get" action="' + link + '" target="_blank"></form>')
$("body").append(frm);
frm.submit().remove();
}
jsFiddle demo
Do not use target="_blank"
Always use a specific name for that window, in my case meaningfulName. In this case you save processor resources:
button.addEventListener('click', () => {
window.open('https://google.com', 'meaningfulName')
})
In this way, when you click, for example, 10 times on a button, the browser will always rerender it in one new tab, instead of opening it in 10 different tabs, which will consume much more resources.
You can read more about this on MDN.
jQuery
$('<a />',{'href': url, 'target': '_blank'}).get(0).click();
JavaScript
Object.assign(document.createElement('a'), { target: '_blank', href: 'URL_HERE'}).click();
To open a new tab and stay on the same location, you can open the current page in the new tab, and redirect the old tab to the new URL.
let newUrl = 'http://example.com';
let currentUrl = window.location.href;
window.open(currentUrl , '_blank'); // Open window with the URL of the current page
location.href = newUrl; // Redirect the previous window to the new URL
You will be automatically moved by the browser to a new opened tab. It will look like your page is reloaded and you will stay on same page but on a new window:
Or you could just create a link element and click it...
var evLink = document.createElement('a');
evLink.href = 'http://' + strUrl;
evLink.target = '_blank';
document.body.appendChild(evLink);
evLink.click();
// Now delete it
evLink.parentNode.removeChild(evLink);
This shouldn't be blocked by any popup blockers... Hopefully.
There is an answer to this question and it is not no.
I found an easy workaround:
Step 1: Create an invisible link:
<a id="yourId" href="yourlink.html" target="_blank" style="display: none;"></a>
Step 2: Click on that link programmatically:
document.getElementById("yourId").click();
Here you go! It works a charm for me.
Here's an example of how we can put it inside an HTML tag
<button onClick="window.open('https://stackoverflow.com/','_blank')">Stackoverflow</button>
How about creating an <a> with _blank as target attribute value and the url as href, with style display:hidden with a a children element? Then add to the DOM and then trigger the click event on a children element.
UPDATE
That doesn't work. The browser prevents the default behaviour. It could be triggered programmatically, but it doesn't follow the default behaviour.
Check and see for yourself: http://jsfiddle.net/4S4ET/
This might be a hack, but in Firefox if you specify a third parameter, 'fullscreen=yes', it opens a fresh new window.
For example,
MyPDF
It seems to actually override the browser settings.
The window.open(url) will open the URL in a new browser tab. Below is the JavaScript alternative to it:
let a = document.createElement('a');
a.target = '_blank';
a.href = 'https://support.wwf.org.uk/';
a.click(); // We don't need to remove 'a' from the DOM, because we did not add it
Here is a working example (Stack Overflow snippets do not allow opening a new tab).
There are lots of answer copies suggesting using "_blank" as the target, however I found this didn't work. As Prakash notes, it is up to the browser. However, you can make certain suggestions to the browser, such as to whether the window should have a location bar.
If you suggest enough "tab-like things" you might get a tab, as per Nico's answer to this more specific question for chrome:
window.open('http://www.stackoverflow.com', '_blank', 'toolbar=yes, location=yes, status=yes, menubar=yes, scrollbars=yes');
Disclaimer: This is not a panacea. It is still up to the user and browser. Now at least you've specified one more preference for what you'd like your window to look like.
Opening a new tab from within a Firefox (Mozilla) extension goes like this:
gBrowser.selectedTab = gBrowser.addTab("http://example.com");
This way is similar to the previous solutions, but implemented differently:
.social_icon -> some class with CSS
<div class="social_icon" id="SOME_ID" data-url="SOME_URL"></div>
$('.social_icon').click(function(){
var url = $(this).attr('data-url');
var win = window.open(url, '_blank'); ///similar to above solution
win.focus();
});
This works for me. Just prevent the event, add the URL to an <a> tag, and then trigger the click event on that tag.
JavaScript
$('.myBtn').on('click', function(event) {
event.preventDefault();
$(this).attr('href', "http://someurl.com");
$(this).trigger('click');
});
HTML
Go
I'm going to agree somewhat with the person who wrote (paraphrased here): "For a link in an existing web page, the browser will always open the link in a new tab if the new page is part of the same web site as the existing web page." For me, at least, this "general rule" works in Chrome, Firefox, Opera, Internet Explorer, Safari, SeaMonkey, and Konqueror.
Anyway, there is a less complicated way to take advantage of what the other person presented. Assuming we are talking about your own web site ("thissite.com" below), where you want to control what the browser does, then, below, you want "specialpage.htm" to be empty, no HTML at all in it (it saves time sending data from the server!).
var wnd, URL; // Global variables
// Specifying "_blank" in window.open() is SUPPOSED to keep the new page from replacing the existing page
wnd = window.open("http://www.thissite.com/specialpage.htm", "_blank"); // Get reference to just-opened page
// If the "general rule" above is true, a new tab should have been opened.
URL = "http://www.someothersite.com/desiredpage.htm"; // Ultimate destination
setTimeout(gotoURL(), 200); // Wait 1/5 of a second; give browser time to create tab/window for empty page
function gotoURL()
{
wnd.open(URL, "_self"); // Replace the blank page, in the tab, with the desired page
wnd.focus(); // When browser not set to automatically show newly-opened page, this MAY work
}

Close window with JavaScript background script? (Firefox Extension)

I am currently writing a Firefox extension that opens a new window in my background script. When a user clicks a button on a page the background script executes and opens the window.
So far I have:
// content script
downloadMod(linkToOpen); //button clicked
function downloadMod(url) {
// var test = window.open(url, '_blank');
var myPort = browser.runtime.connect({ name: "cac410c4672fff93bf0d3186636d8876de3dfeb6#temporary-addon"});
myPort.postMessage({ greeting: url });
}
In my background script (the script the above code connects too) I have:
//background script
portFromCS.onMessage.addListener(function (m) {
var test = browser.windows.create({
url: m.greeting,
allowScriptsToClose: true,
});
NOTE: all the code works as expected. However, the trouble comes when closing the window.
I have tried variations of self.close(), window.close(). I even created a function to wait 5 seconds to load the newly created window and then close the page to no avail. All of my attempts come back with the error:
Scripts may not close windows that were not opened by script.
I thought this error was supposed to be removed with the allowScriptsToClose flag?
To close a window you created with browser.windows.create, you need to use browser.windows.remove.
So:
let windowId;
browser.windows.create({url: "http://google.be"}).then((data) => {
windowId = data.id;
});
// Sometime later, use windowId to close the window
setTimeout(function(){
browser.windows.remove(windowId);
}, 5000);

Javascript SetInterval Not Working in IE

I am using window.open to open a popup window and setinterval function to wait and refresh the background page, once the popup is closed.
the code is working fine in Chrome and Firefox but is not working in IE.
Basically the issue is: in IE, it doesn't wait until popup window is closed. It immediately gets refreshed as soon as the popup opens up.
I saw the issue coming in both IE 9 & IE 11.
Any solution for this?
This is the code:
var url = "/apex/VFP_Add";
var win = window.open(url, "Add" ,"width=600, height=300, scrollbars=yes");
win.moveTo(500, 100);
win.focus();
var timer = setInterval(function() {
if(win.closed) {
clearInterval(timer);
window.location.reload();
}
}, 500);
I put alerts just before if(win.closed) check and just after the check. For the first alert, it showed as False. In second alert, after "if check", it showed True. This is very weird because i had not closed the window.
It seems that's a known bug in IE. See this article about it: https://support.microsoft.com/en-us/kb/241109
Their solution is to basically negate the value of win.closed when you detect that it's running in IE. Something like:
if(win.closed || isRunningInIE()) {
clearInterval(timer);
window.location.reload();
}
There are different ways to detect IE, so you can just use your favorite method in place of that isRunningInIE() function.

I need to reload current location js

I need to reload current location(href) via JS :
I have a button that open a new window and when that window closed I need to reload the location in window that was initiator(parent). It is work in my browser, but one said me that his window does not reload( he has last version chrome and mac book)
I have the followin code:
var loginWindow = window.open(...);
loginWindow.focus();
loginWindow.onbeforeunload = function() {
location.reload(); //when the popUp window close
//I even tried this:
window.location.href = window.location.href;
}
but the page not reloaded
AS onbeforeunload does not work here it is recommended to check if the window exists with certain interval Please find the reference link below
