The values passed in are stored in the object. Calling L<element> with just a tag or L<attributes> without an parameters will used the saved attributes. USE tag = HTML; tag.add_attributes( { class => 'navbar' } ); tag.add_attributes( { id => 'foo' } ); tag.add_attributes( { class => 'active' } ); tag.element( 'li' ); # <li class="navbar active" id="foo"> This method has two aliases: add_attribute() and add(). =head2 replace_attribute(attributes) This will replace an attribute value instead of add to existing. USE tag = HTML; tag.add_attributes( { class => 'navbar' } ); tag.add_attributes( { id => 'foo' } ); tag.replace_attributes( { class => 'active' } ); tag.element( 'li' ); # <li class="active" id="foo"> This method has two aliases: replace_attribute() and replace(). =head2 clear_attributes Clears any saved attributes =head2 element(type, attributes) Generates an HTML element of the specified type and with the attributes provided as an optional hash array reference as the second argument or as named arguments. [% HTML.element(table => { border => 1, cellpadding => 2 }) %] [% HTML.element('table', border=1, cellpadding=2) %] [% HTML.element(table => attribs) %] =head1 DEBUGGING The HTML plugin accepts a C<sorted> option as a constructor argument which, when set to any true value, causes the attributes generated by the C<attributes()> method (either directly or via C<element()>) to be returned in sorted order. Order of attributes isn't important in HTML, but this is provided mainly for the purposes of debugging where it is useful to have attributes generated in a deterministic order rather than whatever order the hash happened to feel like returning the keys in. [% USE HTML(sorted=1) %] [% HTML.element( foo => { charlie => 1, bravo => 2, alpha => 3 } ) %] generates: <foo alpha="3" bravo="2" charlie="1"> =head1 AUTHOR Andy Wardley E<lt>abw@wardley.orgE<gt> L<http://wardley.org/> =head1 COPYRIGHT Copyright (C) 1996-2022 Andy Wardley.
