i have a script that looks up an image name based sting name

but i would like it to be able to make a close match using a wildcard

document.getElementById('resultImg').src='flags/'+callCost[0]+'.png';

how can i set callcost[0] to be a closest match to and image in a folder containing *.png images

callcost list

Afghanistan-Kabul
Afghanistan-Mobile
Afghanistan-Mobile-Areeba
Afghanistan-Mobile-Etisalat
Afghanistan-Mobile-Roshan

folder images
Afghanistan.png

so the callcost selection matches the folder image name image

I am trying to understand.

You want to find the first part of the string, everything up to the first "-" dash character:

Afghanistan-Kabul
Afghanistan-Mobile
Afghanistan-Mobile-Areeba
Afghanistan-Mobile-Etisalat
Afghanistan-Mobile-Roshan

and then you want to use that Afghanistan string to load an image called Afghanistan.png?

Is it like this:

France-Paris would go to France.png
England-London would go to England.png
England-London-Heathrow would also go to England.png
England (all by itself) would also go to England.png


Do I understand the question?

Perhaps this will help.

Here is a function called GetImageName that will return the "base" image name given a string that may have dashes in it.

All five examples below return "Afghanistan.png".

<script>
function GetImageName(s)
{
	var dashPos = s.indexOf('-');
	if ( dashPos == (-1) ) return s+'.png';
	return s.substring(0, dashPos)+'.png';
}


alert(GetImageName('Afghanistan-Kabul'));
alert(GetImageName('Afghanistan-Mobile'));
alert(GetImageName('Afghanistan-Mobile-Areeba'));
alert(GetImageName('Afghanistan-Mobile-Etisalat'));
alert(GetImageName('Afghanistan'));

</script>

I think this is what ou're looking for
<script language="JavaScript" type="text/javascript">
<!--
function GetImageName(s) {
    var dashPos = s.indexOf('-');
    if ( dashPos == (-1) ) return s;
    return s.substring(0, dashPos);
}

function callRef() {
    // COUNTRY SELECTOR
    if (document.selector1.select1.options[document.selector1.select1.selectedIndex].value != "0") {
        var callCosts = document.selector1.select1.options[document.selector1.select1.selectedIndex].value;
        callCost = callCosts.split('?');

        //= this is were i want enter your function=> document.getElementById('resultImg').src='flags/90x90/'+callCost[0]+'.png'; 

        document.getElementById('resultImg').src= 'flags/90x90/' + GetImageName(callCost[0]) + '.png'; 

        document.getElementById('rate1').innerHTML=''+callCost[1]+' &#36;/min';
        document.getElementById('rate2').innerHTML=''+callCost[2]+' &#36;/min';      
    }
}
//-->
</script>
