I'm using bootstrap CSS form styles, When a textbox gets a validation error message, I need to put the class "error" on the containg . How can I do this?
Problem is, all the validations fire on ajax before submitting the form, except for my custom validators which only fire on post. So need to make sure it happens 4 both scenarios.
As described in some of the answers at How to add a 'submitHandler' function when using jQuery Unobtrusive Validation?, the settings can be accessed by $("form").data("validator").settings.
And you can then set any valid/invalid class you like:
var settings = $("form").data("validator").settings;
settings.errorClass += " is-invalid";
settings.validClass += " is-valid";
