SYNOPSIS

This class can be used for fields that need to supply JavaScript code for use by scripts in the form. It will render the value returned by a form's js_code_[field_name] method, or the field's js_code attribute.

has_field 'user_update' => ( type => 'JavaScript',
   js_code => q`$('#fldId').on('change', myFunction);`
);

or using a method:

has_field 'user_update' => ( type => 'JavaScript' );
sub js_code_user_update {
   my ( $self, $field ) = @_;
   if( $self->something ) {
      return q`$('#fldId').on('change', myFunction);`;
   }
   else {
      return q`$('#otherFldId').on('change', myOtherFunction);`;
   }
}
#----
has_field 'usernames' => ( type => 'JavaScript' );
sub js_code_usernames {
    my ( $self, $field ) = @_;
    return q`$('#fldId').on('change', myFunction);`;
}

or set the name of the rendering method:

has_field 'user_update' => ( type => 'JavaScript', set_js_code => 'my_user_update' );
sub my_user_update {
  ....
}

or provide a 'render_method':

 has_field 'user_update' => ( type => 'JavaScript', render_method => \&render_user_update );
