Hi!

I know how to code a link.

But can you code that link to open in a new browser tab?

Or a new browser window?

Whether the new page opens in a new tab or new window is a function of
the user's setting for their browser. Also, if the user's browser
setting is to open a new tab, whether that tab remains behind the prior
tab or is in front of it is a function of another user's setting.
Nothing you do in the HTML will affect whether the user gets a new
window or a new tab, and nothing will affect whether a new tab is behind
or in front of the prior tab.

That may be the case today. But I remember in the early to mid 2000s
first the pop ups (over / front) and then the pop unders (under /
behind) wars. So there was a way that you could influence things to be
behind or in front years ago. I don't know if it is still the case today.

Then there are pop-up blockers which will thwart this.

And let's not speak about the div tags with Z value that puts them in
front of all of the content in the single page / tab.

My experience with this years ago surprised me somewhat.

Don't think of it as a "new tab" so much as a "named tab". Meaning that
the link gets opened in the tab with the name of the target. That tab
will be new if it doesn't already exist. If it does already exist, it
will be the existing window.

With this in mind, I took to having links open in different targets:

<a href="https://www.w3docs.com/" target="w3docs">w3docs</a>
<a href="https://www.wikipedia.com/" target="wikipedia">Wikipedia</a>

The value of the name can be random if you want. But the different
links should use different target values if you want different tabs for
them.

At least that's how I remember things being 10+ years ago.

Wrong - target="_blank" will always open a link a a new tab or window
and the user can not prevent this.

Therefore I generally recommend against this! I user can always decide
to open a link in a new tab if he wants to - but if target="_blank" is
present a user can NOT force the browser to open the link in the current
tab/window. Mostly this is only done for SEO to keep the current web
site open even if you link to another site.

No, the behavior of that is entirely up to the browser (and usually the
user's preferences). It opens a new WINDOW, which the Browser may decide
to open as a tab, or not.

It is also possible to attempt to open a new window using JavaScript, but
most browsers block this as abusive behavior (again, depending on user
preferences, but blocking so-called pop-ups is often the default
behavior).

s is all correct, but _blank and _new are special cases.

No, you do not understand. The markup target="_blank" will open a new
page without closing the page containing that markup. Whether that new
page is in a new tab or a new window is controlled by the user's
browser, not by the markup.

In the version of SeaMonkey that I use, there are three separate sets of
options:
* For a link intended to open a new window (e.g., target="_blank") when
viewing someone else's Web page, I have the option of (1) replacing the
current window or tab, (2) opening a new tab in the current window, or
(3) actually opening a new window. I have selected option #2.
* When a script wants to open a new window, I have the option of (1)
open a new tab in the current window, (2) replace the current window, or
(3) open a new window. I have selected option #1.
* For a link not in a Web page in my browser but in some other
application (e.g., in an E-mail message [not using SeaMonkey's E-mail],
in the About window of some application), I have the option of (1)
replace the current browser window, (2) open a new tab in the current
browser window, or (3) launch a new browser window. I have selected
option #3.

NOTE WELL: I control where the new Web page appears. The parent Web
page -- my own or someone else's -- or other application does NOT
control this.

No - the user can *not* prevent getting a new tab or window.

And *no* option offers to *ignore* targets.

> NOTE WELL: I control where the new Web page appears. The parent Web

No - you don't. If target attribute is present you CAN NOT prevent a new
tab or window to be opened. You can only decide if it's a tab or a
window. But in any case a *new* tab or window *will* open if a link
contains target="_blank".

On the other hand - *without* target="_blank" you *ARE* in control. You
can decide just to click the link and open it in the current tab *or*
you can use the context menu for the link (right mouse button or touch
and hold the link for a while on touch devices) and choose to open it in
a new tab or window.

I hope you understand now what my point is here.

Yes - but the browser WILL ALWAYS open something new! A user CAN NOT
prevent this if target="_blank" is present.

Therefore I recommend NOT to do this on a regular basis but only for
very special cases where the user will understand *why* a new tab or
window will open when clicking the link.

As defined in the HTML Specification(s), that is not so for certain reserved
“target” attribute values:

"_self": same window/tab
"_blank": new tab (tabbed browsing) or window (windowed browsing)
"_parent": parent frame
"_top": topmost frame

> At least that's how I remember things being 10+ years ago.

Next time, RTFM instead:

<https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a>

The “target” attribute can be used with named frames in the same way.

The default behavior is often to block popups *that the user did not cause
consciously*, different from what you describe in the first sentence:
*those* popups are NOT blocked by default.

A proper way to do this would be

<a href='foo' target='bar'
onclick='return !window.open(this.href, this.target,
"width=200,height=200")'
>…</a>

The advantage of additionally using client-side DOM scripting here is that
it is more likely that a window will be opened instead of a tab, that
properties of that window can be suggested (here: viewport width and height,
in pixels), and that fallback approaches can be tried (for example, showing
an element instead of a popup if the latter does not work).

However, spaghetti code like above should be avoided, for example by using
a custom method that is only passed the essential information –

<a href='foo' target='bar'
onclick='return !my.open(this, {width: 200, height: 200})'
>…</a>

– or by adding event listeners dynamically (caveat: the listeners will not
work before the document was loaded), for example

document.addEventListener('load', function () {
document.links['link-foo'].addEventListener(
'click',
function (e) {
if (my.open(
e.target || e.srcElement,
{width: 200, height: 200}))
{
e.preventDefault();
return false;
}
},
false);
});

…

<a href='foo' target='bar' id='link-foo'>…</a>

A possibility for a fallback then would be

let my = {
open: function (target, props) {
let w = null;

if (!(w = window.open(target.href, target.target,
Object.entries(props).map((entry) => `${entry[0]}=${entry[1]}`)
.join(','))))
{
/* If the popup window cannot be created, create an element box
with the content */
if (…)
{
/* If that worked, prevent default action */
w = true;
}
}

/* Prevent default action if any of the above worked */
return w;
}
};

It certainly is possible, though I don't know if any current browsers
support that user option. But yes, there is nothing preventing a browser
for having an option "Do not allow clicks to open a new window."

Opening new windows for users is a speedy way to piss them off, and
using pop-=up windows is a sure way to lose users and have them never
return to your site.

thankfully not many people do user-hostile shot like that. If I got to a
site that did that I would drop into the shell at add them to my hosts
list so I could never load the site again.

Not HTML now, so not really relevant to this discussion. But yeah, don't
do shit like that, it makes people very angry when new windows open on
their screens.

My Web site includes a glossary of Internet terms, targeted to novices.
(There will always be novices.) Other pages on my site contain terms
defined in that glossary. Where that occurs, I have a link to the term
within the glossary; that link uses target="glossary".

According to the browser in use and its settings, the first time such a
link is clicked, this either opens a new tab or a new window, in either
case at the linked term. Subsequent clicks on links for other terms do
not open another glossary page but shift the existing glossary page to
the new term. This allows the user to maintain his or her place on the
page using the term while also seeing terms defined.

If I remember correctly, Firefox did have such an option back in the
day when web dee-zign-urz used target= a whole lot. I remember using
that option to cause such links to be opened in the same tab, unless
I Ctrl-clicked on them.

In fact no browser has this option - so it's pointless to mention that
this *could* be done technically to justify the use of target="_blank".
