getValue of getOptions for dcr select item

Hi,
I have a dcr which has a select item
[html]

Area
Select Outcome title. This is a required field.

[/html]
Using FormApi I want to get the value of the selected item. However, I can only seem to get the index value of the select items.
In the javascript file I have


IWEventRegistry.addItemHandler("/area", "onItemChange", setName);

function setName(areaItem) {
var areaVar=IWDatacapture.getItem("/area");

for (a in areaVar.getOptions()) {
alert (a);
}
}

I now get a prompt for the index of each item in the select item but nothing I do will give me the value from the select item definitions.
I have tried all sorts of combinations of getOptions[].getValue() and getValue[].getOptions[] or similar.
Any one any ideas ?

Thanks.

IWItem.getOptions ()

Returns:
An array of JavaScript Option objects representing the list of options in this select,
checkbox, or radio item, in order. Returns null if this item has no options.

you can access the js option object simply via its value.

var areaVar=IWDatacapture.getItem("/area");
var areaOptions = areaVar.getOptions();
// example: get second object value
alert(areaOptions[1].value);

Continuing from the earlier given example:
var areaOptions = areaVar.getOptions(); //gives all options as an array object
var numOptions = areaOptions.length;

Can also be written as:
var numOptions = areaVar.getOptions().length; //Gives you the total number of options
