Server Side Javascript

[Simon Harris]

Hi All,

I have just taken on maintenance of an app developed in ASP with JavaScript
as the language.

I am struggling with carrying out some math on a value derived from the
querystring:

if (Request.QueryString != "") {
nPage = Request.QueryString("Page");
} else {
nPage = 1;
}

How do I program this so that nPage is an integer, rather than a string when
it comes from the querystring? I have tried this:

....
nPage = cInt(Request.QueryString("Page"));
....

This results in the following error:
Microsoft JScript runtime error '800a138f'
Object expected

If I don't do this, when I use the variable nPage later on (To add it to
another number) I get NaN error. (Not a number - E.g Trying to add a string
to a number)

Any help will be much appreciated.

Thank you.

Simon.

Yup. cInt is a VBScript function. JScript doesn't knkow what it is.

^^^^^^^^^^

nPage = cInt(Request.QueryString("Page"));

Obviously, this is VBScript. You probably want something like:

nPage = +Request.QueryString("Page").Item || 1 // 1 is default
