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?

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.

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.

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".

That's what I was thinking as well, but I cannot say for certain.

I think iCab and/or OmniWeb did this too, about 15-20 years ago.
