NAME

Data::FormValidator::ErrMsgs::JavaScript - Let JavaScript handle DFV error presentation.

SYNOPSIS

 use Data::FormValidator::ErrMsgs::JavaScript (qw/&dfv_js_error_msgs/);

 # In a DFV profile:
 msgs => \&dfv_js_error_msgs,

Now your error messages will come out like this:

 <script type="text/javascript">dfv_error_msg('field_name');</script>

FUNCTIONS

dfv_js_error_msgs

See SYNOPSIS above for syntax.

It's up to you define the dfv_error_msg function in JavaScript to do something interesting.

This function respects the following msgs configuration directives, which are documented more in Data::FormValidator:

 prefix
 any_errors

Of course, these can't be set directly in the profile anymore because the callback is there. They can still be set through the defaults system documented in Data::FormValidator.

LIMITATIONS

More detail could be passed through to the JavaScript function about the failure. This may change in the future, perhaps in an incompatible way.

It is not currently possible to use a format string other than the one provided.

Workarounds included sending a patch or using this routine as the basis for your own.

That workaround might look like this:

 msgs => dfv_js_error_msgs({
    format => 'foo: %';
 });

A closure could then be created which passing in the arguments you want.

FUTURE

If you like this extension to Data::FormValidator, give me some feedback on the Data::FormValidator list and we'll work out a stable interface.
