Passing MULTIPLE values using URL string

NG,

I got the following issue;

Would like to transfer multiple values from a fill-in form to a second
page using string

<programming> A sequence of {data} values, usually {bytes},
	which usually stand for {characters} (a "character string").
	The {mapping} between values and characters is determined by
	the {character set} which is itself specified implcitly or
	explicitly by the environment in which the string is being
	interpreted.

	The most common character set is {ASCII} but, since the late
	1990s, there has been increased interest in larger character
	sets such as {Unicode} where each character is represented by
	more than eight {bits}.

	Most programming languages consider strings (e.g.
	"124:shabooya:\n", "hello world") basically distinct from
	numbers which are typically stored in fixed-length {binary} or
	{floating-point} representation.

	A {bit string} is a sequence of {bits}.

s in the URL.

Have got it worked out for one value allready;

On page with form (using ASP)
this script; http://www.rhi.nl/temp/contact.txt (view source)

I use the following;

Response.Redirect("bedankttr.htm?"+Trouwdd.Value+"");

Of course I can edit this to
Response.Redirect("bedankttr.htm?"+Trouwdd.Value+""+Naam.Value+"");

But can not make it work on destination page to pull

<messaging> A model of media distribution were the bits of
	content have to be requested by the user, e.g. normal use of
	{HTTP} on the {World-Wide Web}.

	Opposite: "{push media}".

out the second value
on another place.

On destination page (for example
http://www.rhi.nl/contact/bedankttr.htm?01-01-2008)
I have putted in;
<script type="text/JAVAscript">
<!--
newVar=location.search;
document

1. <application> Any specific type of {file} produced or
	edited by a specific {application}; usually capable of being
	printed.  E.g. "Word document", "Photoshop document", etc.

	2. <hypertext> A term used on some systems (e.g. {Intermedia})
	for a {hypertext} {node}.  It is sometimes used for a
	collection of nodes on related topics, possibly stored or
	distributed as one.

	3. <programming> To write {documentation} on a certain piece
	of code.

	(2003-10-25)

.write(newVar.substr(1));
//-->
</script>

How do I distill the second value from the string?

In {object-oriented programming} sending a message to an
	{object} (to invoke a {method}) is equivalent to calling a
	{procedure} in traditional programming languages, except that
	the actual code executed may only be selected at run time
	depending on the {class} of the object.  Thus, in response to
	the message "drawSelf", the method code invoked would be
	different if the target object were a circle or a square.

How do I distill the second value from the string?

Brr, not a very nice strategy in my opinion, but if you feel you must
use this strategy, how about doing something like this:

Response.Redirect("bedankttr.htm?Trouwdd=" +
encodeURIComponent(Trouwdd.Value) +
"&Naam=" + encodeURIComponent(Naam.Value));

Then adjust the code

<software> Instructions for a computer in some programming
	language, often {machine language}.  The word "code" is often

	contrast with "{hardware}" and may consist of more than just
	code.

ly does not matter whether or not such a HTML

<hypertext, World-Wide Web, standard> (HTML) A {hypertext}
	document format used on the {World-Wide Web}.  HTML is built
	on top of {SGML}.  "Tags" are embedded in the text.  A tag
	consists of a "<", a "directive" (in lower case), zero or
	more parameters and a ">".  Matched pairs of directives, like
	"<title>" and "</title>" are used to delimit text which is to
	appear in a special place or style.

	Links to other documents are in the form

	 <a href="http://machine.edu/subdir/file.html">foo</a>

	where "<a>" and "</a>" delimit an "anchor", "href" introduces
	a hypertext reference, which is most often a {Uniform Resource
	Locator} (URL) (the string in double quotes in the example
	above).  The link will be represented in the browser by the
	text "foo" (typically shown underlined and in a different
	colour).

	A certain place within an HTML document can be marked with a
	named anchor, e.g.:

	 <a name="baz">

	The "fragment identifier", "baz", can be used in an href by
	appending "#baz" to the document name.

	Other common tags include <p> for a new paragraph, <b>..</b>
	for bold text, <ul> for an unnumbered list, <pre> for
	preformated text, <h1>, <h2> .. <h6> for headings.

	{HTML} supports some standard {SGML} {national characters} and
	other non-{ASCII} characters through special {escape
	sequences}, e.g. "&eacute;" for a lower case 'e' with an acute
	accent.  You can sometimes get away without the terminating
	semicolon but it's bad style.

	Most systems will ignore the case of tags and attributes but
	lower case should be used for compatibility with {XHTML}.

1. A program which provides some service to other ({client})
	programs.  The connection between client and server is
	normally by means of {message passing}, often over a
	{network}, and uses some {protocol} to encode the client's
	requests and the server's responses.  The server may run
	continuously (as a {daemon}), waiting for requests to arrive
	or it may be invoked by some higher level daemon which
	controls a number of specific servers ({inetd} on {Unix}).

	There are many servers associated with the {Internet}, such as
	those for {HTTP}, {Network File System}, {Network Information
	Service} (NIS), {Domain Name System} (DNS), {FTP}, {news},
	{finger}, {Network Time Protocol}.  On Unix, a long list can

not defined by the language standard. Therefore, using that code is
very unwise.

I have never heard of this 'well-known' problem before.

where the vast majority of JAVAScript programmers who do not use Usenet

<messaging> /yoos'net/ or /yooz'net/ (Or "Usenet news", from
	"Users' Network") A distributed {bulletin board} system and
	the people who post and read articles thereon.  Originally
	implemented in 1979 - 1980 by Steve Bellovin, Jim Ellis, Tom
	Truscott, and Steve Daniel at Duke University, and supported
	mainly by {Unix} machines, it swiftly grew to become
	international in scope and, before the advent of the
	{World-Wide Web}, probably the largest decentralised
	information utility in existence.

	Usenet encompasses government agencies, universities, high
	schools, businesses of all sizes, and home computers of all
	descriptions.  In the beginning, not all Usenet hosts were on
	the Internet.  As of early 1993, it hosted over 1200
	{newsgroups} ("groups" for short) and an average of 40
	megabytes (the equivalent of several thousand paper pages) of
	new technical articles, news, discussion, chatter, and
	{flamage} every day.  By November 1999, the number of groups
	had grown to over 37,000.

	To join in you originally needed a {news reader} program but
	there are now several web gateways such as {Deja
	(http://www.deja.com/)}.  Several {web browsers} include news
	readers and {URLs} beginning "news:" refer to Usenet
	newsgroups.

	{Network News Transfer Protocol} is a {protocol} used to
	transfer news articles between a news {server} and a {news
	reader}.  The {uucp} {protocol} was sometimes used to transfer
	articles between servers, though this is probably rare now
	that most sites are on the {Internet}.

	{Stanford University} runs a service to send news articles by
	{electronic mail}.  Send electronic mail to
	<netnews@db.stanford.edu> with "help" in the message body.

It really does not matter whether or not such a HTML UA (not only a browser)
can be named by anyone. Programming in a way that is specified to be
error-prone (see ES3, 8.6.2 §8) is irresponsible, incompetent Voodoo

<logic> (=> or a thin right arrow) A binary {Boolean} function
	and {logical connective}.  A => B is true unless A is true and
	B is false.  The {truth table} is

		A B | A => B
		----+-------
		F F |   T
		F T |   T
		T F |   F
		T T |   T

	It is surprising at first that A => B is always true if A is

it could fail. Speaking
of which, the specification is very difficult to understand. I assume I have
misunderstood the following sentence, because it sounds very strange to me:

"Host objects may implement these methods in any manner unless specified
otherwise; for example, one possibility is that [[Get]] and [[Put]] for a
particular host object indeed fetch and store

[[HasProperty]] always generates false."

Anyway, getting back on topic: I have rewritten the code to which you
objected. I suspect you still won't like it because as with much of my code
it makes use of ECMAScript Edition 3 feature

<jargon> 1. A good property or behaviour (as of a program).
	Whether it was intended or not is immaterial.

	2. An intended property or behaviour (as of a program).
	Whether it is good or not is immaterial (but if bad, it is
	also a {misfeature}).

	3. A surprising property or behaviour; in particular, one that
	is purposely inconsistent because it works better that way -
	such an inconsistency is therefore a {feature} and not a
	{bug}.  This kind of feature is sometimes called a {miswart}.

	4. A property or behaviour that is gratuitous or unnecessary,
	though perhaps also impressive or cute.  For example, one
	feature of {Common LISP}'s "format" function is the ability to
	print numbers in two different Roman-numeral formats (see
	{bells, whistles, and gongs}).

	5. A property or behaviour that was put in to help someone
	else but that happens to be in your way.

	6. A bug that has been documented.  To call something a
	feature sometimes means the author of the program did not
	consider the particular case, and that the program responded
	in a way that was unexpected but not strictly incorrect.  A
	standard joke is that a bug can be turned into a {feature}
	simply by documenting it (then theoretically no one can
	complain about it because it's in the manual), or even by
	simply declaring it to be good.  "That's not a bug, that's a
	feature!" is a common catch-phrase.  Apparently there is a
	Volkswagen Beetle in San Francisco whose license plate reads
	"FEATURE".

	See also {feetch feetch}, {creeping featurism}, {wart}, {green
	lightning}.

	The relationship among bugs, features, misfeatures, warts and
	miswarts might be clarified by the following hypothetical
	exchange between two hackers on an airliner:

	A: "This seat doesn't recline."

	B: "That's not a bug, that's a feature.  There is an emergency
	exit door built around the window behind you, and the route
	has to be kept clear."

	A: "Oh.  Then it's a misfeature; they should have increased
	the spacing between rows here."

	B: "Yes.  But if they'd increased spacing in only one section
	it would have been a wart - they would've had to make
	nonstandard-length ceiling panels to fit over the displaced
	seats."

	A: "A miswart, actually.  If they increased spacing throughout
	they'd lose several rows and a chunk out of the profit margin.
	So unequal spacing would actually be the Right Thing."

	B: "Indeed."

	"Undocumented feature" is a common euphemism for a {bug}.

	7. An attribute or function of a {class} in {Eiffel}.

	[{Jargon File}]

	(1995-10-22)

s (splitting on regular
expressions and decodeURIComponent, for example) but I do not think it
contains anything that'd break

1. To cause to be {broken} (in any sense).  "Your latest patch
	to the editor broke the paragraph commands."

	2. (Of a program) To stop temporarily, so that it may
	debugged.  The place where it stops is a "{breakpoint}".

	3. To send an {EIA-232} break (two character widths of line
	high) over a {serial line}.

	4. [Unix] To strike whatever key currently causes the tty
	driver to send SIGINT to the current process.  Normally,
	break, delete or {control-C} does this.

	5. "break break" may be said to interrupt a conversation (this
	is an example of verb doubling).  This usage comes from radio
	communications, which in turn probably came from landline
	telegraph/teleprinter usage, as badly abused in the Citizen's
	Band craze a few years ago.

Voodoo programming implies that the code concerned should not really work
but happens to do so for reasons only a real expert could figure out.

That is what I mean, for the most part. It should not really work because
host objects do not have to support

After-sale handholding; something many software vendors
	promise but few deliver.  To hackers, most support people are
	useless - because by the time a hacker calls support he or she
	will usually know the software and the relevant manuals better
	than the support people (sadly, this is *not* a joke or
	exaggeration).  A hacker's idea of "support" is a tte--tte
	or exchange of {electronic mail} with the software's designer.

augmentation (specified, and there are
known cases where this provision is implemented). Depending on the DOM
implementation, the attempt of augmentation can do anything from failing
silently to causing an error message. People who employ host object
augmentation nevertheless just do not know any better (which "doesn't fully
understand" applies to) or refuse to see the implications of their doing
(which "irresponsible" and "incompetent"'d apply to). However, one does
_not_ have to be an *expert* _not_ to do either one.

1. <programming> An {address}, from the point of view of a
	programming language.  A pointer may be typed, with its {type}
	indicating the type of data to which it points.

	The terms "pointer" and "reference" are generally
	interchangable although particular programming languages often
	differentiate these two in subtle ways.  For example, {Perl}
	always calls them references, never pointers.  Conversely, in
	C, "pointer" is used, although "a reference" is often used to
	denote the concept that a pointer implements.

	{Anthony Hoare} once said:

	Pointers are like jumps, leading wildly from one part of the
	data structure to another.  Their introduction into high-level
	languages has been a step backward from which we may never
	recover.

	[C.A.R.Hoare "Hints on Programming Language Design", 1973,
	Prentice-Hall collection of essays and papers by Tony Hoare].

	2. <operating system> (Or "mouse pointer") An {icon}, usually
	a small arrow, that moves on the screen in response to
	movement of a {pointing device}, typically a {mouse}.  The
	pointer shows the user which object on the screen will be
	selected etc. when a mouse button is clicked.

doing, as your code does not seem to handle

1. <programming, operating system> A simple item of data that
	identifies a resource.  For example, a {Unix} file handle
	identifies an open file and associated data such as whether it
	was opened for read or write and the current read/write
	position.  On the {Macintosh}, a handle is a pointer to a
	pointer to some dynamically-allocated memory.  The extra level
	of indirection allows on-the-fly {memory compaction} or
	{garbage collection} without invalidating application program
	references to the allocated memory.

	2. <jargon> An alias used intended to conceal a user's true
	identity in an electronic message.  The term is common on
	Citizen's Band and other amateur radio but, in that context
	usually means the user's real name as {FCC} rules forbid
	concealing one's identity.

However, your observation is correct that in my code I try to provide for
fallbacks where there are some. They aren't only there for backwards
compatibility but also meant for educational purposes. (As my libraries are
mostly distributed as free software, anyone can use them in a modified form
that is more fitted to their needs, provided that the modification is
documented and that my original authorship is mentioned.)

(although maybe I have misunderstood what you're doing, as your code
does not seem to handle environments that implement the split function but
do not understand the form using regular expressions).

As you can see in the currently only slightly updated ECMAScript Support

JScript 3.0 which are the exact versions RegExp support was introduced with.PointedEars
