630 A module modeled a bit after Rails' ActionView helpers. Several small
631 functions that create HTML tags from various kinds of data sources.
635 =head2 LOW-LEVEL FUNCTIONS
639 =item C<name_to_id $name>
641 Converts a name to a HTML id by replacing various characters.
643 =item C<attributes %items>
645 Creates a string from all elements in C<%items> suitable for usage as
646 HTML tag attributes. Keys and values are HTML escaped even though keys
647 must not contain non-ASCII characters for browsers to accept them.
649 =item C<html_tag $tag_name, $content_string, %attributes>
651 Creates an opening and closing HTML tag for C<$tag_name> and puts
652 C<$content_string> between the two. If C<$content_string> is undefined
653 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
654 are key/value pairs added to the opening tag.
656 C<$content_string> is not HTML escaped.
660 =head2 HIGH-LEVEL FUNCTIONS
664 =item C<select_tag $name, $options_string, %attributes>
666 Creates a HTML 'select' tag named C<$name> with the contents
667 C<$options_string> and with arbitrary HTML attributes from
668 C<%attributes>. The tag's C<id> defaults to C<name_to_id($name)>.
670 The C<$options_string> is usually created by the
671 L</options_for_select> function. If C<$options_string> is an array
672 reference then it will be passed to L</options_for_select>
675 =item C<yes_no_tag $name, $value, %attributes>
677 Creates a HTML 'select' tag with the two entries C<yes> and C<no> by
678 calling L<select_tag> and L<options_for_select>. C<$value> determines
679 which entry is selected. The C<%attributes> are passed through to
682 =item C<input_tag $name, $value, %attributes>
684 Creates a HTML 'input type=text' tag named C<$name> with the value
685 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
686 tag's C<id> defaults to C<name_to_id($name)>.
688 =item C<hidden_tag $name, $value, %attributes>
690 Creates a HTML 'input type=hidden' tag named C<$name> with the value
691 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
692 tag's C<id> defaults to C<name_to_id($name)>.
694 =item C<submit_tag $name, $value, %attributes>
696 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
697 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
698 tag's C<id> defaults to C<name_to_id($name)>.
700 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
701 be added via the C<onclick> handler asking the question given with
702 C<$attributes{confirm}>. If request is only submitted if the user
703 clicks the dialog's ok/yes button.
705 =item C<textarea_tag $name, $value, %attributes>
707 Creates a HTML 'textarea' tag named C<$name> with the content
708 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
709 tag's C<id> defaults to C<name_to_id($name)>.
711 =item C<checkbox_tag $name, %attributes>
713 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
714 HTML attributes from C<%attributes>. The tag's C<id> defaults to
715 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
717 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
718 created with said C<label>. No attribute named C<label> is created in
721 If C<%attributes> contains a key C<checkall> then the value is taken as a
722 JQuery selector and clicking this checkbox will also toggle all checkboxes
723 matching the selector.
725 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
727 Creates a date input field, with an attached javascript that will open a
728 calendar on click. The javascript ist by default anchoered at the bottom right
729 sight. This can be overridden with C<cal_align>, see Calendar documentation for
730 the details, usually you'll want a two letter abbreviation of the alignment.
731 Right + Bottom becomes C<BL>.
733 =item C<radio_button_tag $name, %attributes>
735 Creates a HTML 'input type=radio' tag named C<$name> with arbitrary
736 HTML attributes from C<%attributes>. The tag's C<value> defaults to
737 C<1>. The tag's C<id> defaults to C<name_to_id($name . "_" . $value)>.
739 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
740 created with said C<label>. No attribute named C<label> is created in
743 =item C<javascript_tag $file1, $file2, $file3...>
745 Creates a HTML 'E<lt>script type="text/javascript" src="..."E<gt>'
746 tag for each file name parameter passed. Each file name will be
747 postfixed with '.js' if it isn't already and prefixed with 'js/' if it
748 doesn't contain a slash.
750 =item C<stylesheet_tag $file1, $file2, $file3...>
752 Creates a HTML 'E<lt>link rel="text/stylesheet" href="..."E<gt>' tag
753 for each file name parameter passed. Each file name will be postfixed
754 with '.css' if it isn't already and prefixed with 'css/' if it doesn't
757 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
759 Creates a date input field, with an attached javascript that will open a
760 calendar on click. The javascript ist by default anchoered at the bottom right
761 sight. This can be overridden with C<cal_align>, see Calendar documentation for
762 the details, usually you'll want a two letter abbreviation of the alignment.
763 Right + Bottom becomes C<BL>.
765 =item C<tabbed \@tab, %attributes>
767 Will create a tabbed area. The tabs should be created with the helper function
771 L.tab(LxERP.t8('Basic Data'), 'part/_main_tab.html'),
772 L.tab(LxERP.t8('Custom Variables'), 'part/_cvar_tab.html', if => SELF.display_cvar_tab),
775 An optional attribute is C<selected>, which accepts the ordinal of a tab which
776 should be selected by default.
778 =item C<areainput_tag $name, $content, %PARAMS>
780 Creates a generic input tag or textarea tag, depending on content size. The
781 amount of desired rows must be either given with the C<rows> parameter or can
782 be computed from the value and the C<cols> paramter, Accepted parameters
783 include C<min_rows> for rendering a minimum of rows if a textarea is displayed.
785 You can force input by setting rows to 1, and you can force textarea by setting
788 =item C<multiselect2side $id, %params>
790 Creates a JavaScript snippet calling the jQuery function
791 C<multiselect2side> on the select control with the ID C<$id>. The
792 select itself is not created. C<%params> can contain the following
799 The label of the list of available options. Defaults to the
800 translation of 'Available'.
804 The label of the list of selected options. Defaults to the
805 translation of 'Selected'.
809 =item C<sortable_element $selector, %params>
811 Makes the children of the DOM element C<$selector> (a jQuery selector)
812 sortable with the I<jQuery UI Selectable> library. The children can be
813 dragged & dropped around. After dropping an element an URL can be
814 postet to with the element IDs of the sorted children.
816 If this is used then the JavaScript file C<js/jquery-ui.js> must be
817 included manually as well as it isn't loaded via C<$::form-gt;header>.
819 C<%params> can contain the following entries:
825 The URL to POST an AJAX request to after a dragged element has been
826 dropped. The AJAX request's return value is ignored. If given then
827 C<$params{with}> must be given as well.
831 A string that is interpreted as the prefix of the children's ID. Upon
832 POSTing the result each child whose ID starts with C<$params{with}> is
833 considered. The prefix and the following "_" is removed from the
834 ID. The remaining parts of the IDs of those children are posted as a
835 single array parameter. The array parameter's name is either
836 C<$params{as}> or, missing that, C<$params{with}>.
840 Sets the POST parameter name for AJAX request after dropping an
841 element (see C<$params{with}>).
845 An optional jQuery selector specifying which part of the child element
846 is dragable. If the parameter is not given then it defaults to
847 C<.dragdrop> matching DOM elements with the class C<dragdrop>. If the
848 parameter is set and empty then the whole child element is dragable,
849 and clicks through to underlying elements like inputs or links might
852 =item C<dont_recolor>
854 If trueish then the children will not be recolored. The default is to
855 recolor the children by setting the class C<listrow0> on odd and
856 C<listrow1> on even entries.
862 <script type="text/javascript" src="js/jquery-ui.js"></script>
864 <table id="thing_list">
866 <tr><td>This</td><td>That</td></tr>
869 <tr id="thingy_2"><td>stuff</td><td>more stuff</td></tr>
870 <tr id="thingy_15"><td>stuff</td><td>more stuff</td></tr>
871 <tr id="thingy_6"><td>stuff</td><td>more stuff</td></tr>
875 [% L.sortable_element('#thing_list tbody',
876 url => 'controller.pl?action=SystemThings/reorder',
879 recolor_rows => 1) %]
881 After dropping e.g. the third element at the top of the list a POST
882 request would be made to the C<reorder> action of the C<SystemThings>
883 controller with a single parameter called C<thing_ids> -- an array
884 containing the values C<[ 6, 2, 15 ]>.
888 Dumps the Argument using L<Data::Dumper> into a E<lt>preE<gt> block.
890 =item C<sortable_table_header $by, %params>
892 Create a link and image suitable for placement in a table
893 header. C<$by> must be an index set up by the controller with
894 L<SL::Controller::Helper::make_sorted>.
896 The optional parameter C<$params{title}> can override the column title
897 displayed to the user. Otherwise the column title from the
898 controller's sort spec is used.
900 The other parameters in C<%params> are passed unmodified to the
901 underlying call to L<SL::Controller::Base::url_for>.
903 See the documentation of L<SL::Controller::Helper::Sorted> for an
904 overview and further usage instructions.
908 =head2 CONVERSION FUNCTIONS
912 =item C<options_for_select \@collection, %options>
914 Creates a string suitable for a HTML 'select' tag consisting of one
915 'E<lt>optionE<gt>' tag for each element in C<\@collection>. The value
916 to use and the title to display are extracted from the elements in
917 C<\@collection>. Each element can be one of four things:
921 =item 1. An array reference with at least two elements. The first element is
922 the value, the second element is its title.
924 =item 2. A scalar. The scalar is both the value and the title.
926 =item 3. A hash reference. In this case C<%options> must contain
927 I<value> and I<title> keys that name the keys in the element to use
928 for the value and title respectively.
930 =item 4. A blessed reference. In this case C<%options> must contain
931 I<value> and I<title> keys that name functions called on the blessed
932 reference whose return values are used as the value and title
937 For cases 3 and 4 C<$options{value}> defaults to C<id> and
938 C<$options{title}> defaults to C<$options{value}>.
940 In addition to pure keys/method you can also provide coderefs as I<value_sub>
941 and/or I<title_sub>. If present, these take precedence over keys or methods,
942 and are called with the element as first argument. It must return the value or
945 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
946 precedence over each individual sub. It will only be called once for each
947 element and must return a list of value and title.
949 If the option C<with_empty> is set then an empty element (value
950 C<undef>) will be used as the first element. The title to display for
951 this element can be set with the option C<empty_title> and defaults to
954 The option C<default> can be either a scalar or an array reference
955 containing the values of the options which should be set to be
958 =item C<tab, description, target, %PARAMS>
960 Creates a tab for C<tabbed>. The description will be used as displayed name.
961 The target should be a block or template that can be processed. C<tab> supports
962 a C<method> parameter, which can override the process method to apply target.
963 C<method => 'raw'> will just include the given text as is. I was too lazy to
964 implement C<include> properly.
966 Also an C<if> attribute is supported, so that tabs can be suppressed based on
967 some occasion. In this case the supplied block won't even get processed, and
968 the resulting tab will get ignored by C<tabbed>:
970 L.tab('Awesome tab wih much info', '_much_info.html', if => SELF.wants_all)
972 =item C<truncate $text, %params>
974 Returns the C<$text> truncated after a certain number of
977 The number of characters to truncate at is determined by the parameter
978 C<at> which defaults to 50. If the text is longer than C<$params{at}>
979 then it will be truncated and postfixed with '...'. Otherwise it will
980 be returned unmodified.
