JavaScript form validation

I've got a form that I want to test to make sure the user entered a zip code in a valid array and I'm not sure how to check it...

The zip code list is like 11111, 11114, 11117, so I can't just include a range...

I had written a function like:

Code:

---

function validate_zip(field,alerttxt)
{
        with (field)
        {
                if (value==null||(value<"11111"||value>"11174"))
                  {alert(alerttxt);return false;}
                else {return true}
        }
}

---

but, I have to exclude the non-inclusive zip codes...so, how do I create an array and test against it???

TIA!!!

I just wrote this basic function you can use to find a value in an array.

PHP Code:

---

<script type="text/javascript">
var zipArray = new Array("11111","11112","11113","11114");

function inArray(v,a)
{
    for(i = 0; i < a.length; i++)
    {
        if(v == a[i])
        {
            return true;
        }
    }
    return false;
}

// Usage
alert(inArray('11114',zipArray));// returns true
alert(inArray('11115',zipArray));// returns false
</script>
