Updating validator options
← ejemplos
When setting validator options for fields, the usual way is
$(form).formValidation({
fields: {
fieldName: {
validators: {
validatorName: {
// The error message
message: '...',
// Other validator options
// ...
}
}
}
}
});The following example demonstrates the ability of updating message and validator options on the fly. It is simple job application form which asks user to upload the correct file based on the selected job position.
The validator options can be updated via the updateOption() method.
Although message is common option of all validators, FormValidation provides the
updateMessage() method to update it instead of
updateOption().
To update message of validators supporting dynamic message, in additional to calling the updateMessage() method, you also might need to use the updateOption() method as following:
$(form).formValidation('updateMessage', field, validatorName, newMessage);
$(form).formValidation('updateOption', field, validatorName, 'message', newMessage);
