Zipcode to County help

[dpwsmw]

I am new to Java, so I was wondering, If I have a form that someone inputs the Zipcode in one field that it can autofill the other with the county, this is for a small number of counties and like 20 ZipCodes. So is it like an if then statement.

I would appreciate any help with this. thanks

well, if you mean JavaScript, then we can help. Java is something different entirely.

you can try something like this:

<script type="text/javascript"><!--

// array of zip codes 
var zc = new Array(11545, 06513, 06514, 11542);

// array of towns
var cc = new Array('Glen Head', 'East Haven', 'Hamden', 'Glen Cove');

function fill() {
    // get zip code field
    var zo = document.forms['f'].elements['z'];

    // get town field
    var co = document.forms['f'].elements['c'];
    
    // loop through zip codes
    for ( var i = 0; i < zc.length; i++ ) {
        if ( zc[i] == zo.value ) {
            co.value = cc[i];
            return;
        }
    }
}

//--></script>

<form name="f">
    <input type="text" name="z" onchange="fill();" />
    <input type="text" name="c" />
</form>

this isn't a very complete method of course, you'll need to change it to suit your needs. it should get you started though.
