aPossible to Make A "Dummy" Anchor Tag **without** Jumping Back Up???

Hi, People,

Is it possible to have an "empty" or "dummy" <a href***without***
the browser jumping back up the page??

I have a hyperlink that doesn't point to another document, but is used
to call forth a modal window onClick (or is there another way, without
text or image links, of calling forth JavaScript on user activity??).
I would like to spare my visitors the inconvenience and visually
jarring effect of getting thrown back up to the top of the page! =(

re: aPossible to Make A "Dummy" Anchor Tag **without** Jumping Back Up???

Ah, well, using "javascript:;" for a value did the trick! The browser
no longer throws the viewer back up to the top of the page.

Unfortunately, that modal window doesn't center vertically, so *it* is
still up at the top of the page!

How can I center an element *vertically*, please?

It's just a box, actually, and I know that with CSS "auto" centers it
horizontally -- but what about vertically??

jump to the normal href destination.

It's then a good idea to make the href value a URL to a separate page
with the same content as the attempted popup, so as to make that
content accessible to non-JavaScript users.

If the element is not really a hyper link why marking it as such?
Better use generic SPAN element or A(nchor) element without 'href'
and attach 'click' handler to it. This will spare your visitors the
confusion with encountering hyper links which are not really hyper
links.

Apart from that from the incorrect hyper link usage note, you could
always return false in the 'click' handler to prevent the browser
from doing its default action - to follow the link:

<script type="text/javascript">
function openWindow(url, name, features) {
if (open) {
var n = (name) ? name : "_blank";
var f = (features) ? features : "resizable,scrollbars";
var win = open(url, n, f);
if (win) {
return false;
}
}
return true;
}
</script>

<a href="http://www.w3.org/"
onclick="return openWindow(this.href);">W3C</a>

Thanks, this just might be the ticket! I'll have to give it a shot --
but it looks like it will work! (At least I can understand the
example in theory!)

Yes, it says just so in Chapter 4, Rollover Buttons, of "The Book of
JavaScript, Second Edition!" Damn, in one ear, out the other....
Actually, the href doesn't point to a document, but to text that's
invisible until invoked by an onClick, creating that modal window.

God, what a dilemma! Just what in heck am I supposed to do about
those people (like me!) whose IE7 disabled ActiveX Controls??

Now onMouseOver/onMouseOut sound intriguing, but they seem like they'd
be "intrusive" insofar as they would probably be unexpected....

As it is, this hyperlink issue is solved -- but I'll have another one
soon! ;-)

re: aPossible to Make A "Dummy" Anchor Tag **without** Jumping Back Up???

Say, just as an update: it turns out that I was able to achieve
vertical alignment by simply using the position:fixed property and
value, in conjunction with margin:23% (it was originally margin:
400px)....

I may have lucked out, though, as I'm not sure exactly how it's
working in the code I've got (below)...also rather bummed that Sam
Collison's good if dry CSS book didn't discuss the vertical-align
property at all despite listing it in the appendix!


#overlay div
{
width:300px;
margin: 23% auto;
background-color: #fff;
border:1px dashed #000;
padding:15px;
text-align:center;
position:fixed;
left: 38%;
}

re: aPossible to Make A "Dummy" Anchor Tag **without** Jumping Back Up???

Ackk!!

That position:fixed property and value has an odd visual artifact in
Firefox 2! (It has a different one in Opera 9!)

The modal window that's "on" the page is invisible until turned on by
a function that's called onClick -- except when scrolling the webpage,
without having clicked on the hyperlink that calls the function: text
scrolling past that invisible modal window "drags by" in the form of
that modal window! It's like when in the Schwarzenegger movie
"Predator" the alien goes invisible, but you can still see the vague
"shimmer" of its outline, especially when it moves....

In Opera 9, position:fixed causes the bottom half of the text in the
modal window to not display if that modal window pops up below "the
fold" (the halfway scroll-point of a webpage)!

Can somebody tell me what's the matter with all this?? Some kind of
inheritance bugaboo??

#overlay div
{
width:300px;
margin: 23% auto;
background-color: #fff;
border:1px dashed #000;
padding:15px;
text-align:center;
position:fixed;
left: 38%;
}

Yes, <a href="#foo" name="foo">. But why would you do that? It's 100.1%
certain that you don't understand what your real problem is and that you
are consequently creating new problems.
So what made you use a link when you don't want to link?
Yes of course. Read any introduction to basics of the elements of using
client-side scripting on www pages. Make sure it's a modern one that
discusses the problem "how do I create the <input type="button"element
dynamically so that it does not appear when it does not work, i.e. when
scripting is disabled?".
Spare them the nasty effects of creating new windows for them.

I'm working on my site, which involves CSS and JavaScript in addition
to HTML and general design issues.
Hmmm, using a name or id attribute stops the browser from trying to
follow the href the way a "javascript:;" or "return false;" does?
Interesting!

"Very possible. That's why I'm asking around!
Well, the user has to have a way of calling forth information in that
modal window. (And no I really do want that information in a modal
window instead of "cluttering" up the rest of my paragraph.)
Hmm, an input button! I would need it very small, though...I'm using
a modal window like a footnote, see, or an endnote...I wonder if I can
style that button to be visually minuscule....
But that's the thing -- I don't want a webpage full of footnotes, or
redirect the user to another page full of endnotes. A modal window is
the only way I can think of where somewhat extraneous information can
still be offered...unless...I use some kind of "thought balloon"??
Hey, can I do them Ajax-style onMouseOver balloons with *JavaScript*??
Why? The topic of modal windows and how to best implement them seems
relevant to all the newsgroups I'd chosen.

what I'm trying to do!)...instead of footnotes on every page, I
figured I'd present such information as an option. That means a
button or a link, right?

So clicking a link -- say, an asterisk -- brings up a modal window.
That way, the page itself is not cluttered by extraneous info but the
user has the option of viewing it.

I could use a button, but unless buttons can be made as small as an
asterisk, I think a hyperlink is what I have to use.

Or is there anything else other than a hyperlink or button?

In the meantime, I'm considering onMouseOver "help balloons" instead,
instead of onClick modal windows. Help balloons seem less intrusive
and in-your-face than modal windows.

Any more advice much appreciated.
