Need help with onClick inside an Anchor & SSL

[Will]

(My 4 questins at end after explination) The code below was provided to me
to "Popup" a window explaining what a Credit Card Verification Number is and
where to find it on a card... it is used as people enter their credit card
info on an ecommerce site. This is the first such site (Shopping Cart) I
have done and this code was provded by a user of the standard ASP Shopping
Cart software (CandyPress shopping cart.)

It works, but I don't think it is good code... but I haven't done ASP in a
long tme.

==========HERE IS THE CODE (FORMATTED FOR EASY READING)======= =====

<a href="<%=urlNon SSL%>Card_Verif _Examp.htm" TITLE="What is Card
Verification Number?"

onClick='window .open("<%=urlNo nSSL%>Card_Veri f_Examp.htm",
"cardverificati on",
"width=550,
height=610,
resizable=1,
scrollbars=1")

;return false;' target="_blank" > What is Card Verification Number? </a>
========== EASY READING FORMATTED CODE ENDS =============== =========

========== CODE STARTS - Exactly as it appears in program =====
<a href="<%=urlNon SSL%>Card_Verif _Examp.htm" TITLE="What is Card
Verification Number?"
onClick='window .open("<%=urlNo nSSL%>Card_Veri f_Examp.htm","c ardverification "
,"width=550,hei ght=610,resizab le=1,scrollbars =1");return false;'
target="_blank" >What is Card Verification Number?</a>

========= CODE ENDS =============== =============== ====

QUESTION 1: The code seems redundant to me with the reference to
"Card_Verif_Exa mp.htm" appearing twice.
QUESTION 2: What is the... TITLE="Bla Bla" part? I'm not familar with that
tag in an Anchor Link.
QUESTION 3: Is there a more simple way to create this code?
QUESTION 4: What is the "cardverificati on" paramater right after the
onClick='window .open("<%=urlNo nSSL%>Card_Veri f_Examp.htm", ???

thanks for any help on this - Will

It is. See below.
QUESTION 2: What is the... TITLE="Bla Bla" part? I'm not familar with
that tag in an Anchor Link.
It's not a tag; it's an attribute. Elements have start and end tags. The
starting tag for any element can contain one or more attributes that
specify certain properties for that element. See
<URL:http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2> for more
detailed information.

As for the title attribute itself, it annotates an element. Usually it's
rendered as a tooltip. See
<URL:http://www.w3.org/TR/html4/struct/global.html#h-7.4.3>. The title
attribute is applicable to virtually every element, by the way.
QUESTION 3: Is there a more simple way to create this code?
<a href="<%=urlNon SSL%>Card_Verif _Examp.htm" target="_blank"
title="What is a card verification number?"
onclick="window .open(this.href ,this.target,
'width=550,heig ht=610,resizabl e,scrollbars');
return false;">

This uses the attribute values in the link to create the window. The this
operator yields an object reference that represents the element, and I'm
sure you can guess what the properties after the dot (.) yield.
QUESTION 4: What is the "cardverificati on" paramater right after the
onClick='window .open("<%=urlNo nSSL%>Card_Veri f_Examp.htm", ???

It specifies a window or frame name. If that window exists, the url is
opened there. If not, it's created.

Hope that helps,
Mike

It is. Use this.href in the JavaScript to reference the URI from the href
attribute.
QUESTION 2: What is the... TITLE="Bla Bla" part? I'm not familar with that
tag in an Anchor Link.
http://w3.org/TR/html4/

It provides advisory information about the element, browsers often render
this as a tooltip.
QUESTION 3: Is there a more simple way to create this code?
By not opening a new window, or putting the information on the same page (it
shouldn't take much space to type "The last three digits on the signature
strip on the back of the card" and add a small picture!)
QUESTION 4: What is the "cardverificati on" paramater right after the
onClick='window .open("<%=urlNo nSSL%>Card_Veri f_Examp.htm", ???

The window name. (Yes, for some reason the author can't decide between
"_blank" and "cardverificati on". I'd switch to this.target ... if I were
going to open a new window).
