Have just found this on the net (won't take the credit for this code as it's from www.webreference.com):

function numeralsOnly(evt) {
    evt = (evt) ? evt : event;
    var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode : 
        ((evt.which) ? evt.which : 0));
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        alert("Enter numerals only in this field.");
        return false;
    }
    return true;
}

The field's event handler would be configured like the following:

onkeypress="return numeralsOnly(event)"
