While I am a programmer I am not a javascript programmer. I'm looking for a script I can alter for my purposes.

Right now I have several javascripts that simply return a text string. They're all basically the same information but each script returns the info in a slightly different format (one script returns basic info for a sidebar, one returns longer info for a page)

What I'd like is a script that can be called with a variable, and the script uses that variable to determine what text gets returned.

Is this even possible?

Sure it is - there are several ways of doing this, such as:

Code: 
function doSomething(someVar) {
   if (someVar == 'abc' || someVar == 'jkl') {
      return('def');
   } else if (someVar == 'ghi') {
      return('xyz');
   } else {
      return('123');
   }
}

Or you could use a switch statement:

Code: 
function doSomething(someVar) {
   var retVal = '';
   switch (someVar) {
      case 'abc':
      case 'jkl':
         retVal = 'def';
         break;
      case 'ghi':
         retVal = 'xyz';
         break;
      default:
         retVal = '123';
         break;
   }
   return(retVal);
}

Hope this helps,
Dan

Yes and no...

I discovered that if I call two consecutive scripts that variable values carry over from the first to the second, so I used one script to set a variable and the second to return the text based on the variable.

Thank you.

Code: 
<html>
<head>

<script type="text/javascript">
function myfunction(txt, foo)
{
switch (foo)
{
case 1:
  alert(txt);
  break
case 2:
  alert(txt.substring(0,10)+"...");
  break
default:
  alert("Sorry, the item could not be found");
}
}
</script>

</head>
<body>

<form>
<input type="button" 
onclick="myfunction('Hello, this is a string which is very long', 1)"
value="Get full text">
<input type="button" 
onclick="myfunction('Hello, this is a string which is very long', 2)"
value="Get short text">
<input type="button" 
onclick="myfunction()"
value="Get default text">
</form>

<p>By pressing the button, a function with an argument will be called. The function will alert
this argument.</p>

</body>
</html>
