parse URL

[fred rosenberg]

hi,

i would like a button in an application i am writing to go out to my web
site and check to see if there is a later application update available.
here is how i think
it needs to be done, but please redirect me if i got this wrong.

I pass a "parameter" in the URL, e.g.
www.abc.com/VersionCheck.htm?userversion=2.0,
and then have the web page parse the URL and compare the user's version with
the
current version.

is this the proper way to do it? any examples of HTML that does this kind
of thing?

(i'm using FP 2003).

thanks!

fred

Hi Fred,

That will work provide the page VersionsCheck has logic (JavaScript) to check the version against a table in the page.

Here is a javascript function you can use that parses the value out of a querystring

Rhond

function getVersion(

//get the version from the querystring.

var sVersion = new Object()
var querystring = location.href.substring(1)
var qs = querystring.split("?");
for(var i = 0; i < qs.length; i++)
var pos = qs.indexOf('=');
if (pos == -1) continue;
var argname = qs.substring(0,pos);
var value = qs.substring(pos+1);
sVersion[argname] = unescape(value);

if ((sVersion[argname] == "") || (qs.length == 1)

return "MAP"

els

return sVersion[argname]

OOps. Forgot to change one line before posting. This is a function I have used in one of apps and I changed to reflect the version. My default value that I was looking for happened to "MAP" you probably want your default value to be a certain version number. This code only gets executes in the case where the address gets executed with a blank querysting. So if someone went to www.abc.com/VersionCheck.htm for insance without the ?useversion=2.0 on it. Make sense

Rhond

function getVersion(

//get the version from the querystring.

var sVersion = new Object()
var querystring = location.href.substring(1)
var qs = querystring.split("?");
for(var i = 0; i < qs.length; i++)
var pos = qs.indexOf('=');
if (pos == -1) continue;
var argname = qs.substring(0,pos);
var value = qs.substring(pos+1);
sVersion[argname] = unescape(value);

if ((sVersion[argname] == "") || (qs.length == 1)

return "1.0"

els

return sVersion[argname]

Just to add another note. Inside your html you would need to execute that

function. Like on the onload event of the page.
