This function will do what you want.

Code:

function get_val(){
	obj = document.forms[0].elements[0];	//The dropdown
	sel=[];

	sel[0]=obj[obj.selectedIndex].value;	//Option Value
	sel[1]=obj[obj.selectedIndex].text;	//Option Text

	return sel;
}

This is a fully working example, cut and paste into a new blank html doc. When you select a value in either text box it will show you what you picked in a message box

Code:

<html>
<head>
<title>Select info demo</title>
<script>
	function get_val(obj){
		sel=[];

		sel[0]=obj[obj.selectedIndex].value;		//Option Value
		sel[1]=obj[obj.selectedIndex].text;		//Option Text

		//return sel;
		alert('Value:\t'+sel[0]+'\nText:\t'+sel[1])
	}
</script>
</head>

<body>

<form>
	<select onchange="get_val(this)">
		<option value="val0">text0</option>
		<option value="val1">text1</option>
		<option value="val2">text2</option>
		<option value="val3">text3</option>
	</select>

	<select onchange="get_val(this)">
		<option value="val4">text4</option>
		<option value="val5">text5</option>
		<option value="val6">text6</option>
		<option value="val7">text7</option>
	</select>
</form>
</body>
</html>

I mean like the values are

woof
google
meow

and three arrays with them

woof[]
google[]
meow[]

and I want to know how to get the array that is named after the value so I can use it to write a combo-box control

You can use the eval(String) function to pickup objects variables and execute functions whose names correspond to the supplied string.

Off the top of my head this code should return your arrays based on supplying the words woof, google, meow to it.

Code:

var woof=[]
var google=[]
var meow=[]

function return_array(val){
	if(typeof eval(val) is "object"){
		return eval(val);
	} else {
		return false;
	}
}

//useage
woofArray = return_array('woof');

volks[2] = "Passat";

var alltogether;

function return_array(val){
if(typeof eval(val) is "object"){
return eval(val);
} else {
return false;
}
}

function add_options(typelist)
 {
  if( typelist == "model" )
  {
  var typelist = window.document.boogle.google;
  var dropdownchange = window.document.boogle.noodle;
  }

  var typelist = return_array(typelist[typelist.selectedIndex].value);
  
  for(var i=0;i <dropdownchange.length ; i++)
   { 
    dropdownchange.options[i].text = typelist[i];
   }
  while(dropdownchange.length <typelist.length)
   {
    var new_option = new Option;
    new_option.text = typelist[dropdownchange.length];
    dropdownchange.options[dropdownchange.length]= new_option;
   }
  }
//let them put there glasses on -->
</SCRIPT>
