My browser (firefox) prevents any popup from loading, and loads links that open new windows in the current tab, unless I explicitly say I want the link to load on a new tab or window, with the appropriate shortcuts (for example, middle click on the link, or left click with ctrl pressed causes the link to open on a new tab, and shift + left click on a new window).
I would like to create a javascript function f() that runs some code (meant to create the link address) when the link is pressed, and then loads the link that has been created, without removing the user experience described above.
Right now what I have is something like <a href="javascript:void(0)" onclick="f()"/>, but middle click doesn't work (it instead loads the url javascript:void(0)) and neither do the other features described above.
Do you have any idea as how to solve my problem ?
Thanks.
have you tried window.open('url')?

Also, as far as I know, you can't control whether or not the browser opens in a new tab or new window. That is a browser setting that is different for every user.
You might also try removing the onclick, and using
EDIT
There seems to be issues with using middle click with opening new tabs instead of executing the javascript: middle click (new tabs) and javascript links
As that site says, you can instead create an id for the element and bind it through javascript.
**Taken from that link:
...
And then in your JS, hook the link via it's ID to do the AJAX call.
Remember that you need to stop the click event from bubbling up. Most
frameworks have an event killer built in that you can call (just look
at its Event class).
Here's the event handling and event-killer in jquery:
$("#thisLink").click(function(ev, ob) {
alert("thisLink was clicked");
ev.stopPropagation();
});
Without jQuery, it might look like this:
document.getElementById('thisLink').onclick = function(e)
{
//do someting
e.stopPropagation();
}
Other browsers may vary, but by default Firefox doesn't tell the web page that it has been middle-clicked (unless you set the hidden preference to enable the feature). You might be able to create a workaround based on the focus and/or mouseover events instead.

I'm trying to create a simple JS function that will open a new window/tab when clicking a specific button, so the user will actually open 2 windows/tabs, however no matter what I do, one of the links gets blocked by Chrome as a "popup-blocked".
I'd like to do something like this:
$(document).ready(function(){
$("a").mousedown(function(){
window.open("https://stackoverflow.com/","_blank");
});
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Click Me!
;
But when I do this, the button link doesn't work, but the JS does.
If I change the JS and add a setTimeout() to it, the button URL goes through but the JS gets blocked.
No matter what I do, I can't get both of them to go through.
Any help would be appreciated.
Navigating to two places at once, with one in a new window, is really popular with people who want to show the user a massive advert in a new window.
Massive adverts are unpopular with users, so browsers take steps to prevent this behaviour.
Sometimes legitimate uses get caught in the crossfire. Blame the blackhat end of the advertising industry.
You'll need to find some other way to display… whatever it is you want to display… to the user that doesn't involve navigating to multiple webpages at the same time in separate windows.
The problem is caused by the mousedown() event you are using which is a part of down+up sequence to trigger the click() event of the <a> tag.
so opening a new window "breaks" the flow and browser is not tracking for the mouse-up event anymore to follow the original url.
so the solution is to attach the click() event instead without stopping propagation. this will fire the attached and original events and none of them will be blocked.
$(document).ready(function(){
$("a").click(function(){
window.open("https://stackoverflow.com/","_blank");
});
})
you can try sample on this page as stackoverflow snippet is sandboxed and is blocking popups
On my site, I have a div container, which contains a <input>, and a <a onclick="DoSomeStuff();" href="#" target="_blank"> element, which acts as a button. Now, DoSomeStuff(); modifies the href attribute based on the value of the input element.
I need to emulate click on this anchor tag after user pressed enter on an input element. I know how to detect this enter, but I don't know how to click this anchor. jQuery's .click() is not working in here, it only fires onclick() of the anchor tag, but does not actually click the anchor.
Edit: Here is an example on what I want to do: http://jsfiddle.net/JZYWZ/. It triggers the onclick event of the anchor tag, but does not follow the link in new tab.
Browsers are very strict about opening links in new tabs/windows through javascript.
If they allowed you to have javascript click and open a new tab when the user presses enter (for what you know to be legitimate reasons), that feature could be abused by spammers to have javascript click ads and spam links when the user does anything. Sadly there's no way the browser can tell your linked page is legitimate and not spam or monetised clickbait.
Pretty much the only option to open the url in new tab using javascript is window.open which you've already tried: the browser will always look to the user's settings on popup blocking and on whether to open in tabs or windows - and the default settings are strict, particularly in Firefox and Internet Explorer (less so in Chrome and Safari).
A possible alternate approach where you won't be fighting the browser's anti-spam defences is to open the content in a modal overlay (iframe-based if you need multiple pages). Here's one example library.
It'll be similar from a UI point of view - giving the user related content in a form where they can just close it and return to the main page when they're done with it.
Modal overlays are widely used and likely to be familiar with users. For example, they're now pretty standard for sharing pages, logins and other pieces of simple interaction or side content. Example:
EDIT
After some additional testing....
$('input[type="text"]').on('keyup', function(event){
if(event.keyCode === 13){
DoSomeStuff();
window.open($('a').attr('href'));
}
});
I've got a browser plug-in I'm working on and I want it to behave a certain way when the user clicks things. Not limited to, but including, a behavior for links!
The problem is that the plug-in has to work for a wide variety of sites, and some of those sites use the dreaded pseudo-protocol such as:
Show Element
Currently my behavior is added to the anchor tag via
anchor.addEventListener('click', superAwesomeFunction);
Unfortunately this has a problem where the click listener only fires once. If I preventDefault() of course the click listener sticks around, but I've now broken the host site! Otherwise, clicking the link fires the click listener but only on the first click. I'm wondering why my superAwesomeFunction() doesn't fire again if the link is clicked a second time. Is href="javascript:things()" doing more than I know?
It is possible to add an event listener to a link that has a JavaScript function call set in the href attribute.
Here's a jsFiddle that shows it working. Both functions fire each time the link is clicked.
There must be something else going on with your code beyond what we can see in what you gave us.
If you must wait user some time and going on url then, you may add some code to your superAwesomeFunction's process end:
document.location.href = $(this).attr("href");
Is it possible to capture the right click open in new window/tab or mouse wheel open in new window/tab event using jQuery?
UPDATE 1
Here is why I need it. I have codeigniter application which uses pagination class. I use this class to display a grid. The pagination links have been bind with a method that uses AJAX to load the next page in a container div. Now some one can right click and open the next page in new tab/window which I don't want. IMHO, the only way to handle this is to some how trap the (right click or mouse wheel button click) open in new window/tab event.
UPDATE 2
I just realised all my AJAX requests are being served by one CI controller which actually acts as a proxy to other classes/libs. In this controller I can look at the request and if it isn't an AJAX request I can redirect the user to another page.
A workaround solution is to replace all applicable <a> elements with buttons, where (obviously) the buttons would call JavaScript that does the appropriate navigation.
If you're really keen you can apply CSS to make the buttons look like <a> elements, though I don't recommend it because it confuses users who might try to treat them as standard links and right- or middle-click them.
(You could even get it to work for users that don't have JavaScript enabled by, e.g., making each button a submit button in its own little form.)
At the very least you can catch a right-click, using .mousedown() (or, presumably, mouseup()). See this StackOverflow answer about right clicks for more. And by catching it, you should be able to do a standard event.preventDefault() and then do as you like from there. That may be overkill, however, as it could prevent the user from doing other things you want to allow them to do.
I almost fixed a similar issue now for a page which I am working on. My fix was to do some changes in the page if that has been opened in a new window....
Assume that you open a page "B" from page "A" in a new window.
If you want to check the page "B" is opened in a new window from page "A", then follow the below steps..
If (document.referrer == "A" && window.history.length > 1) {
alert("I am page 'B' and opened from page 'A' in a new window");
}
If you don't want people to access link the usual way or fallback when the JS is disabled, then it shouldn't be a link. Just use any element you like (span, div, button, whatever you like) and style it like a link. Then bind the action using JS. Or you can use a link with href="#" or href="javascript: void(0)". That way if users right click it and choose to open in a new window, then they will end up in the same page they were before.
Google toolbar is creating a serious problem for me in IE 6 when i try to open a window using window.open or if i set target="_blank" for anchor tag. It treats the window as pop up and dispaly pop up is blocked which i really don't want to dsiplay to my user. This problem only occurs if there is a extra code getting executed before window.open, e.g. calling another method at onclick then using window.open. Can somebody tell me how to solve this issue?
The toolbar and other devices like that are intended to protect users from unwanted popup windows. The only way for them to determine whether a window is "wanted" is to determine whether window.open is being called in an event handler for a user-initiated event, like a button click. Thus if you try to do something like call window.open on document load, or in an AJAX success handler, the toolbar (and other blockers) will assume that the popup is suspect.
There's nothing you can do about this other than, as noted by Mr. Buchan, tell your users what to expect. Wherever possible, have your popups launched directly from click handlers.
A more radical change would be to shift away from window.open and use simulated popup windows made from floating elements that cover up part of the page. Something, that is, like what jQuery UI dialogs give you.
Adding the site to your Trusted Sites will work.
Setting target="_blank" shouldn't be triggering a pop-up blocker.
