METHODS $self->add( $element ) Adds a new element. $self->elements( ) Returns a ref-array of all added elements. $self->output( ) Returns the javascript-code. $self->output_for_html( < \%args > ) Returns the javascript-code that can be directly embedded into html-code. Optimal \%args: Key-value pairs that reprensent attributes that will be associated to the script tag. print $code->output_for_html( { language => undef } ); SEE ALSO JavaScript::MochiKit AUTHOR Sascha Kiefer, "esskar@cpan.org" LICENSE This library is free software, you can redistribute it and/or modify it under the same terms as Perl itself.
