NAME

       HTML::FormHandler::Render::RepeatableJs - role providing method to construct repeatable
       javascript

VERSION

       version 0.40068

SYNOPSIS

       Creates jQuery javascript to add and delete repeatable elements.

       Note: This is still EXPERIMENTAL.  This is an EXAMPLE.  Changes are very likely to occur.
       Javascript is not guaranteed to be best practice.  It will not work on all rendered
       repeatables (requires wrapper with id).  It is strongly suggested that you make your own
       role if you use it.  Then you can modify it as needed.  Or just write out the rep_ data to
       javascript variables, and write the function in javascript.  This function uses a plain
       javascript confirmation dialog.  You almost certainly want to do something else.  This
       javascript depends on the Repeatable field having a 'controls' div class in order to
       position the new elements. Use the Bootstrap wrapper or the 'controls_div' tag on the
       Simple wrapper.

       A role to be used in a Form Class:

           package MyApp::Form::Test;
           use HTML::FormHandler::Moose;
           extends 'HTML::FormHandler';
           with 'HTML::FormHandler::Render::RepeatableJs';
           ...

   DESCRIPTION
       This contains one method, 'render_repeatable_js'. It's designed to be used in a template,
       something like:

           [% WRAPPER "wrapper.tt" %]
           [% form.render_repeatable_js %]
           <h1>Editing Object .... </h1>
           [% form.render %]
           [% END -%]

       It will render javascript which can be used with the AddElement field, and setting the
       'setup_for_js' flag in the Repeatable field to add the ability to dynamically add a new
       repeatable element in a form.

       Note: this code is provided as an example. You may need to write your own javascript
       function if your situation is different.

       Some of the extra information (level) in this function is in preparation for handling
       nested repeatables, but it's not supported yet.

       This function operates on HTML elements that have the id of the repeatable element. That
       requires that the wrapper have the repeatable instance ID (now rendered by default). If
       you don't have wrappers around your repeatable elements, this won't work.

       See HTML::FormHandler::Field::AddElement for an example of rendering an HTML element that
       can be used to provide the AddElement button.  See that field for the requirements for the
       add HTML.

       See HTML::FormHandler::Field::RmElement for an example of rendering an HTML element that
       can be used to provide a 'remove' button.  See that field for the requirements for the
       remove HTML.
