Hi,I have Javascript to test a value the user enter on a webpage from the Javascript Onload event.

If the value is incorrect, I want to display a message on the page - "Entry Invalid" or "Entry Valid"

I am not sure how to display the custom error.
Thanks

Hi all,

The JS code verify a South African ID number - this is working 100%

If it was entered correctly, it will add the date of birth and the gender, derived from the id number - this works all good.If the number is correct, it will turn green or red if invalid.
I was able to add an JS line "Alert()" - but this is not nice, I just want to add a message at the bottom of the id number field, or just below the id number field, to say "Number Valid" or "Number Invalid" - I am sure this should be simple, but I have never done this before - so ... please assist with this one.
Kind RegardsWalter
Partial code when the number was validated:

if (correct) {
dateofbirth.setValue(dobdate);

genderValue.setValue(gender);

idnumber.addStyle('color: green');


}

// otherwise, show the error

else {



dateofbirth.setValue('');

genderValue.setValue('');

idnumber.addStyle('color: red');



alert("Invalid Number");
}

Check this article for inspiration:

The idea is to create a place holder for your custom message first and then you can use Field Events or any Javascript code to display your message.

Hi,

There is also another solution to this, which may be a bit easier.
This section explain to add custom JS validation, where you add a custom js file to the system and call it from the field properties of a field value to be tested.

Hopefully this will help as well.
