dynamic error messages

[ashish-joshi-sr]

Hi there,

I am making a custom validation in my form. based on the conditions i check, i need to provide errorMessage. I tried to make a global variable which i initialized as empty string and assigned message into it as i check conditions but it doesn't take dynamically.
how can i do this...

What do you mean by "... but it doesn't take dynamically"? Is it the error message that you want to set dynamically? It would be great if you provided me with a code example.

I'd love for something like this as well -

for example

$.formUtils.addValidator({
  name: 'donation_amount',
  validatorFunction: function (value) {
    var donation = numeral(value).format('0,0.00');
    var exist = donation.length > 0;
    var hasCorrectFormat = (numeral(donation).value() > 0.00) && (!donation.startsWith('-'));
    var validity = exist && hasCorrectFormat;

    return validity;
  },
  errorMessage: "Sorry, you've entered an invalid amount to donate.",
  errorMessageKey: 'invalidDonationAmount'
});

I'd love to be able to set a different errorMessage based on the reason the module failed. if exist came out to be false, then I'd love to be able to send 'Please enter a donation amount' as an error message vs just having a generic message.

for what it's worth, I found this - #505, but have not been able to make it work.

This is a duplication of #505.

@angelocordon Can you give me a code example?
