        // do something
    });

Methods

const form = $('form').form('setErrors', {email: 'not valid', password: 'is required'});

ERROR HANDLING

The plugin expects error messages as JSON object.
The key must match the input name field, and the value should contain the error message.
Example:

{
  "first_name": "This field must not be empty",
  "email": "This is not a valid email address",
  "password_repeat": "The password repetition does not match"
}

If the errors are returned properly, the plugin will bring up the error messages in the correct place
and the input fields will be marked as invalid.
