POST to standard HTML and parse parameters in Javascript

[Jay]

Hi,
Does anyone know if you can do an HTML POST to a plain html file using
javascript to receive and parse the parameters, instead of using asp,
php, or a plain-old cgi program?
Thanks,
Jay

You can use J(ava)Script on the server (e.g. in ASP) to process a HTTP
POST request. POSTing data to a plain HTML document should give an error
(usually HTTP 405 Method not allowed).

Does anyone know if you can do an HTML POST to a plain html file using

There is no such thing as a "HTML POST". There is the _HTTP_ POST command
and (therefore) request type, ...

javascript to receive and parse the parameters, instead of using asp,
php, or a plain-old cgi program?

.... which is why that is not possible with _client-side_ scripting. "Using
ASP, PHP, or a plain-old CGI program" involves an HTTP server, which is why
it is possible there. You can use _Server-Side_ JavaScript[tm] of course,
but I think you had a client-only solution in mind. There can be none.

Yeah, I am integrating w/Google Maps and passing a large about of XML
to the webpage via a GET request. Unfortunately there is a limit in
the URL size of about 2083 kb I believe. I believe that using a POST
would allow me to send a larger amount of data. I don't want to stand
up a server or PHP since it is just a single page embedded in an
Internet Explorer ActiveX control. I guess I'll just use COM to invoke
a javascript method and pass the date that way. Thanks for the help!!

Yeah,

Are you referring to something? See below.

More like 2083 _bytes_ (here: characters), and AFAIK in Internet Explorer
only.

I believe that using a POST would allow me to send a larger amount of
data.

Yes, it would.

Not understood. The server you would be POSTing to would be the server
where Google Maps runs on, so you do not need a server of your own. /Iff/
the Google Maps server-side script can handle POST the same way it can
handle GET data, you can make a POST request, using a form[method="POST"],
or an XMLHTTP request object (which is an ActiveX/COM object in IE).
However, with the latter there are some security restrictions (Same Origin
Policy) that may apply here. If these restrictions apply, you will need a
server of your own, though, to facilitate server-side redirection.

I have an html page that embeds a Google Map in a div layer. In order
to customize
what markers and map locations are being displayed I send XML to the
webpage and parse it using Javascript/MSXML2 object. Unfortunately
there is a limit to the size of XML I can pass using a GET request. So
inorder to send larger amounts of date to the webpage, I would have to
standup a server or cgi program that can handle the large request.
Since my app uses an embedded IE control I can query for the
IHTMLDocument COM interface and eventually call a javascript method
directly using
IDispatch.
