Question

I’ve got a page X that is supposed to have hyperlinks to pages A, B, and C if certain conditions are met. What I’m hoping to do is (on the server as the page is being built) is prune out hyperlinks that don’t meet my conditions. The way I would like this to be structured is that in the Javascript function that is building the HTML for the links on X, eval a function that exists in A, B, and C where a true/false is returned which tells me whether or not to include the link.

I’ve written it so far so that X dynamically pieces together the name of the appropriate function to call in A, B, and C based off of their names and uses eval. The problem is that eval doesn’t seem to know where the functions are located.

Since this is server-side, I don’t believe that I can use the tag because I think that’s for client-side code. I don’t want to use the at the top because I want X to be loosely coupled with A, B, and C.

This is Javascript in ASP pages running on IIS.

Any suggestions as to how I can make the eval locate the function on the server is appreciated.

function shouldLink(filename)
{
    filename = "a.asp";
    var splits = filename.split(".");
    var file = splits[0].toUpperCase() + "_ShouldLink()";  // A_ShouldLink() function name built here

    var exec = "<!--#include virtual=\"a.asp\" -->";
    exec += "eval( " + file + " );";

    try{
            return eval( exec );
    } catch( err ){

    }

    return true;
}

Basically at the eval here I want the function named A_ShouldLink() to be called (which resides in a.asp).

I may be wrong but I don’t think you can use include files in this manner. I have never seen include files dynamically added this way.

Try

function shouldLink(filename)
{
    filename = "a.asp";
    var splits = filename.split(".");
    var file = splits[0].toUpperCase() + "_ShouldLink()";  // A_ShouldLink() function  name built here

   Server.Execute(fliename) 
   var exec =  "eval( " + file + " );";

   try{
          return eval( exec );
   } catch( err ){

   }

   return true;

}

You will obviously need to be careful with the path for your file name.
