Hi everyone,

I have defined a complex validation + script in my validation-rules.xml
I declare the validation rule to be applied on a field in the form
but when I try to load the JSP page, I can see that the other checks (like required, minlength etc... are generated, although my own check is not generated. I want to do client checking on this little extra check too because if it's not possible, it's useless (for me) to do checks at the client side at all. The thing that I want to check is that a field A is (almost) equal to a field B, except the final character (which should be A in field A and B in field B). So "0123AA12345A" and "0123AA12345B" will be accepted, otherwise, alert box.

I hope someone already implemented some more complex validation rules and knows how to solve the problem.


-------------------- validation-rules.xml (snipped) --------------
name="vpnBoxIDsCompareEqualExceptAB" classname="com.mycompany.ui.util.validator.VPNBoxIDsCompareEqualExceptAB"
depends="" msg="errors.vpnboxidscompareequalexceptab">
function validateVpnBoxIDsCompareEqualExceptAB(form) {
var field1 = form['fieldA'];
var field2 = form['fieldB'];
var pack = form['packType'];

if (pack.value != 'DoCheck') {return true;}

if (((field1.type == 'text') || (field1.type == 'textarea')) &&
((field2.type == 'text') || (field2.type == 'textarea')) &&
((field1.value.length > 0) || (field2.value.length > 0)))
var sub1 = null;
if (fields1.value.length > 0) {
sub1 = field1.value.substring(0, field1.value.length-1);

var sub2 = null;
if (field2.value.length > 0) {
sub2 = field2.value.substring(0, field2.value.length-1);

if (sub1 == sub2)
if ((field1.value == sub1+'A') && (field2.value == sub2+'B'))
return true;

alert('The permanent VPN Box ID and dial-up VPN Box ID are not the same (except A or B)');
return false;

---------------------------- declare checks on form fields ----------------
<msg name="vpnBoxIDsCompareEqualExceptAB" key="order.status.mask.error.permvpnid"/>
<arg0 key="order.status.vpnbox.permanent"/>
