I have a web page that has the following code...

    switch (optwizsel)
    {
        case "YYP":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard1.js'></scr" + "ipt>");
        break;
        case "YNP":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard2.js'></scr" + "ipt>");
        break;
        case "NYP":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard3.js'></scr" + "ipt>");
        break;
        case "NNP":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard4.js'></scr" + "ipt>");
        break;
        case "YYY":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard5.js'></scr" + "ipt>");
        break;
        case "YNY":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard6.js'></scr" + "ipt>");
        break;
        case "NYY":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard7.js'></scr" + "ipt>");
        break;
        case "NNY":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard8.js'></scr" + "ipt>");
        break;
        case "YYN":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard5.js'></scr" + "ipt>");
        break;
        case "YNN":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard6.js'></scr" + "ipt>");
        break;
        case "NYN":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard7.js'></scr" + "ipt>");
        break;
        case "NNN":
            window.document.write("<scr" + "ipt language='JavaScript' src='setup/alerts/alertwizard8.js'></scr" + "ipt>");
        break;
        default:
        break;
    }

Basically all it does is go through a routine of checking a unix server for the config of certain items and based upon that config writes the appropriate statement in the head to assign the correct external js file.

Here is my question and the advice I am needing...This has the high probability of expanding in the future beyond checking the three config options I am checking today. My concern is complexity and size of the page. Ideally what I would love to do is assign an external js file that simply does the checking and writes the appropriate code line to assign the correct js file to the page. Is this possible? Is it possible to have an external js file that writes to the head an external js file?

And if anyone has any other ideas, I am open to them.

I don't think you can do this, but I would suggest a server language like PHP, ASP or CGI if it works with you.

HTH,

Snib,

Thanks for the advice. Unfortunately, while I would love to use ASP or something of that nature, in this case we cannot. The unix server I am communicating with is not a web server. It is simply a server our company sells with our own custom programs on them and I interact with it. So a server side language is out of the question right now.

Clay Hess

I have another idea: can you make the page a .shtml and then use an #include statement to include your JavaScript from a separate file?

Snib,

Usually when I am including files and such from a server side, I am using ASP. So I am not as familiar with shtml and the ramifications so let me ask you some things...

This webpage is being hosted locally on the users harddrive. Can shtml and the include code reference a local file and not be server side at all? Basically, the only interaction I have with the unix server is getting config info in a boolean format. SO do you think that would work?

Clay Hess

Hmm... I can't get it to work locally, but it would with IIS or Apache installed locally. I know you don't have either on the Unix box, and I'm guessing you don't have them locally, either.

Hope you solve this!

I have IIS on my machine but I of course cannot control what is on the users machine. So that would not work. Let me know if inspiration strikes you again.

How about shuffling your files a bit around, renaming them, and then use this code:

window.document.write("<scr" + "ipt type='text/javascript' src='setup/alerts/alertwizard' + optwizsel + '.js'></scr" + "ipt>");

Endless possibilities. Just change the value of optwizsel and add more .js files.....

Everyone is unique, except for me.

Yeah, that's a good idea. Something like this:

function IS(num) //IS = include script
{
 document.write("<scr" + "ipt type='text/javascript' src='setup/alerts/alertwizard' + num + '.js'></scr" + "ipt>");
}

switch(optwizsel)
{
 case "NNN" : IS(8); break;
}

That would greatly reduce the size of your page.
