automatically choose one of many .js files

Hi!

My index.html calls a .js file (getcontent.js).

<script language="JavaScript" src="getcontent.js">
</script>

I now would like it to automatically call one of my ten .js files
(1getcontent.js, 2getcontent.js and so on), instead of always calling
getcontent.js. And to do this in either a random way, or depending on for
example what hour or minute it is when the file is run.

Is this possible?

Would be glad if someone could help!

Yes. Have getcontent.js pull up the appropraite #getcontent.js file and
execute it. Implementing this is left as an excercise.

Perhaps you can add the last second you get with time in front of
getcontent.js
and then use document.write to load the file.
so if the seconds are 34 you will load 4.getcontent.js
and if the seconds are 56 you will load 6.getcontent.js
This way you'll pick the contant "at random"
How exactly this is done is the exercise as stated by Owen

I thought about doing something like that. After a little more thinking, I
believe I don't need it to be random. I thought about taking the day of the
month (1,2,3...), or as you suggested the last second. But I might have more
"getcontents" in the future, more than 10, so it's probably better with day
of the month, or hour of the day. I suppose there is some "GetDate"
function, that returns 23 if it's the 23:rd?
I am already using document.write to load the file, further down in the
index.html. Looks like this:

<script language="JavaScript"><!--
var before = '<font size="4" <font color="#000000"> <b> <font
face="BernhardFashion BT">';
var after = '</font>';
var content = getcontent();
document.write(before + content + after);
// -->
</script>

I'm really new to all this, but should I really have to bother about this
later part (document.write part)? Shouldn't I just do what Owen told me, to
use getcontent.js to call the other #getcontent.js, and to put what you,
John, suggests (or something similar) in the .js that's named getcontent
(the first one, that calls the others)?
Thanks guys for pointing me in the right direction.

the document.write part was a hint how to implement what owen told you
If you need more different contents you can pick any number of seconds and
with a simple mathematical calculation you can get any lower number of
possibilities.
an axample divide the last 100 seconds by 10 make it an Integer an you have
10 possibilities, divide it by 2 and ypu have 50 possibilities.

This might be a stupid question. Do I have to move the document.write part
from index.html to getcontent.js? I did split the original .js file into 10
separate ones in order to get the load time down, and to be able to call
parts of it separately. And if I have to put the document.write part in
every if - else loop in getcontent.js then there will be quite a lot of
code, and the load time won't be so much faster, am I right?
I was kind of hoping that Owens idea to call the #getcontents.js, would be
able to return, for example, 1getcontent.js back to the document.write part
in index.html. Isn't this possible?

The first javascript (might be part of the HTML file) decides which contents
should be loaded.
To have the browser load that .js file you have to write the script tag with
the created filename as HTML in javascript this is document.write("<script
src='xgetcontents.js'>") or something similar.
In xgetcontents.js there's data that needs to be displayed so this file wil
contain several times document.write().
Perhaps you should created a new OP and post it at a JavaScript newsgroup.

Perhaps this code will help you:

date = new Date();
now = date.getTime();
first = parseInt (now/10, 10);
second = parseInt (now/100, 10);
random = parseInt ((first-(second*10))/1.25,10);

contentfile=eval('<script language="javascript"
src="'+random+'getcontent.js" type="text/javascript"'></script>);
document.write(contentfile);

WARNING: The script tag might be depricated in some ways

Thanks for trying to help, John! I havn't got it working, but I'll try more
tonight. I'll let you know tomorrow.
Once again, thanks!

Johan

I tried to implement your code for a few hours last night, but I didn't
manage. I don't think there's anything wrong with your code, but there's
some other problem. So, I guess I'll have to start thinking about doing it
in another way.
Is it possible to use if - else loops between the <head> tags? Something
like:

if randomnumber = 1
<script language="JavaScript" src="1getcontent.js">
</script>

if randomnumber =2
<script language="JavaScript" src="2getcontent.js">
</script>

If so, then it could be a solution.
