481 A module modeled a bit after Rails' ActionView helpers. Several small
482 functions that create HTML tags from various kinds of data sources.
486 =head2 LOW-LEVEL FUNCTIONS
490 =item C<name_to_id $name>
492 Converts a name to a HTML id by replacing various characters.
494 =item C<attributes %items>
496 Creates a string from all elements in C<%items> suitable for usage as
497 HTML tag attributes. Keys and values are HTML escaped even though keys
498 must not contain non-ASCII characters for browsers to accept them.
500 =item C<html_tag $tag_name, $content_string, %attributes>
502 Creates an opening and closing HTML tag for C<$tag_name> and puts
503 C<$content_string> between the two. If C<$content_string> is undefined
504 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
505 are key/value pairs added to the opening tag.
507 C<$content_string> is not HTML escaped.
511 =head2 HIGH-LEVEL FUNCTIONS
515 =item C<select_tag $name, $options_string, %attributes>
517 Creates a HTML 'select' tag named C<$name> with the contents
518 C<$options_string> and with arbitrary HTML attributes from
519 C<%attributes>. The tag's C<id> defaults to C<name_to_id($name)>.
521 The C<$options_string> is usually created by the
522 L</options_for_select> function. If C<$options_string> is an array
523 reference then it will be passed to L</options_for_select>
526 =item C<input_tag $name, $value, %attributes>
528 Creates a HTML 'input type=text' tag named C<$name> with the value
529 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
530 tag's C<id> defaults to C<name_to_id($name)>.
532 =item C<hidden_tag $name, $value, %attributes>
534 Creates a HTML 'input type=hidden' tag named C<$name> with the value
535 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
536 tag's C<id> defaults to C<name_to_id($name)>.
538 =item C<submit_tag $name, $value, %attributes>
540 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
541 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
542 tag's C<id> defaults to C<name_to_id($name)>.
544 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
545 be added via the C<onclick> handler asking the question given with
546 C<$attributes{confirm}>. If request is only submitted if the user
547 clicks the dialog's ok/yes button.
549 =item C<textarea_tag $name, $value, %attributes>
551 Creates a HTML 'textarea' tag named C<$name> with the content
552 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
553 tag's C<id> defaults to C<name_to_id($name)>.
555 =item C<checkbox_tag $name, %attributes>
557 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
558 HTML attributes from C<%attributes>. The tag's C<id> defaults to
559 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
561 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
562 created with said C<label>. No attribute named C<label> is created in
565 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
567 Creates a date input field, with an attached javascript that will open a
568 calendar on click. The javascript ist by default anchoered at the bottom right
569 sight. This can be overridden with C<cal_align>, see Calendar documentation for
570 the details, usually you'll want a two letter abbreviation of the alignment.
571 Right + Bottom becomes C<BL>.
573 =item C<radio_button_tag $name, %attributes>
575 Creates a HTML 'input type=radio' tag named C<$name> with arbitrary
576 HTML attributes from C<%attributes>. The tag's C<value> defaults to
577 C<1>. The tag's C<id> defaults to C<name_to_id($name . "_" . $value)>.
579 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
580 created with said C<label>. No attribute named C<label> is created in
583 =item C<javascript_tag $file1, $file2, $file3...>
585 Creates a HTML 'E<lt>script type="text/javascript" src="..."E<gt>'
586 tag for each file name parameter passed. Each file name will be
587 postfixed with '.js' if it isn't already and prefixed with 'js/' if it
588 doesn't contain a slash.
590 =item C<stylesheet_tag $file1, $file2, $file3...>
592 Creates a HTML 'E<lt>link rel="text/stylesheet" href="..."E<gt>' tag
593 for each file name parameter passed. Each file name will be postfixed
594 with '.css' if it isn't already and prefixed with 'css/' if it doesn't
597 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
599 Creates a date input field, with an attached javascript that will open a
600 calendar on click. The javascript ist by default anchoered at the bottom right
601 sight. This can be overridden with C<cal_align>, see Calendar documentation for
602 the details, usually you'll want a two letter abbreviation of the alignment.
603 Right + Bottom becomes C<BL>.
605 =item C<tabbed \@tab, %attributes>
607 Will create a tabbed area. The tabs should be created with the helper function
611 L.tab(LxERP.t8('Basic Data'), 'part/_main_tab.html'),
612 L.tab(LxERP.t8('Custom Variables'), 'part/_cvar_tab.html', if => SELF.display_cvar_tab),
615 An optional attribute is C<selected>, which accepts the ordinal of a tab which
616 should be selected by default.
618 =item C<areainput_tag $name, $content, %PARAMS>
620 Creates a generic input tag or textarea tag, depending on content size. The
621 mount of desired rows must be given with C<rows> parameter, Accpeted parameters
622 include C<min_rows> for rendering a minimum of rows if a textarea is displayed.
624 You can force input by setting rows to 1, and you can force textarea by setting
627 =item C<multiselect2side $id, %params>
629 Creates a JavaScript snippet calling the jQuery function
630 C<multiselect2side> on the select control with the ID C<$id>. The
631 select itself is not created. C<%params> can contain the following
638 The label of the list of available options. Defaults to the
639 translation of 'Available'.
643 The label of the list of selected options. Defaults to the
644 translation of 'Selected'.
648 =item C<sortable_element $selector, %params>
650 Makes the children of the DOM element C<$selector> (a jQuery selector)
651 sortable with the I<jQuery UI Selectable> library. The children can be
652 dragged & dropped around. After dropping an element an URL can be
653 postet to with the element IDs of the sorted children.
655 If this is used then the JavaScript file C<js/jquery-ui.js> must be
656 included manually as well as it isn't loaded via C<$::form-gt;header>.
658 C<%params> can contain the following entries:
664 The URL to POST an AJAX request to after a dragged element has been
665 dropped. The AJAX request's return value is ignored. If given then
666 C<$params{with}> must be given as well.
670 A string that is interpreted as the prefix of the children's ID. Upon
671 POSTing the result each child whose ID starts with C<$params{with}> is
672 considered. The prefix and the following "_" is removed from the
673 ID. The remaining parts of the IDs of those children are posted as a
674 single array parameter. The array parameter's name is either
675 C<$params{as}> or, missing that, C<$params{with}>.
679 Sets the POST parameter name for AJAX request after dropping an
680 element (see C<$params{with}>).
684 An optional jQuery selector specifying which part of the child element
685 is dragable. If nothing is given then the whole child element is
686 dragable, and clicks through to underlying elements like inputs or
687 links might not work.
693 <script type="text/javascript" src="js/jquery-ui.js"></script>
695 <table id="thing_list">
697 <tr><td>This</td><td>That</td></tr>
700 <tr id="thingy_2"><td>stuff</td><td>more stuff</td></tr>
701 <tr id="thingy_15"><td>stuff</td><td>more stuff</td></tr>
702 <tr id="thingy_6"><td>stuff</td><td>more stuff</td></tr>
706 [% L.sortable_element('#thing_list tbody',
707 'url' => 'controller.pl?action=SystemThings/reorder',
709 'as' => 'thing_ids') %]
711 After dropping e.g. the third element at the top of the list a POST
712 request would be made to the C<reorder> action of the C<SystemThings>
713 controller with a single parameter called C<thing_ids> -- an array
714 containing the values C<[ 6, 2, 15 ]>.
718 Dumps the Argument using L<Data::Dumper> into a E<lt>preE<gt> block.
722 =head2 CONVERSION FUNCTIONS
726 =item C<options_for_select \@collection, %options>
728 Creates a string suitable for a HTML 'select' tag consisting of one
729 'E<lt>optionE<gt>' tag for each element in C<\@collection>. The value
730 to use and the title to display are extracted from the elements in
731 C<\@collection>. Each element can be one of four things:
735 =item 1. An array reference with at least two elements. The first element is
736 the value, the second element is its title.
738 =item 2. A scalar. The scalar is both the value and the title.
740 =item 3. A hash reference. In this case C<%options> must contain
741 I<value> and I<title> keys that name the keys in the element to use
742 for the value and title respectively.
744 =item 4. A blessed reference. In this case C<%options> must contain
745 I<value> and I<title> keys that name functions called on the blessed
746 reference whose return values are used as the value and title
751 For cases 3 and 4 C<$options{value}> defaults to C<id> and
752 C<$options{title}> defaults to C<$options{value}>.
754 In addition to pure keys/method you can also provide coderefs as I<value_sub>
755 and/or I<title_sub>. If present, these take precedence over keys or methods,
756 and are called with the element as first argument. It must return the value or
759 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
760 precedence over each individual sub. It will only be called once for each
761 element and must return a list of value and title.
763 If the option C<with_empty> is set then an empty element (value
764 C<undef>) will be used as the first element. The title to display for
765 this element can be set with the option C<empty_title> and defaults to
768 The option C<default> can be either a scalar or an array reference
769 containing the values of the options which should be set to be
772 =item C<tab, description, target, %PARAMS>
774 Creates a tab for C<tabbed>. The description will be used as displayed name.
775 The target should be a block or template that can be processed. C<tab> supports
776 a C<method> parameter, which can override the process method to apply target.
777 C<method => 'raw'> will just include the given text as is. I was too lazy to
778 implement C<include> properly.
780 Also an C<if> attribute is supported, so that tabs can be suppressed based on
781 some occasion. In this case the supplied block won't even get processed, and
782 the resulting tab will get ignored by C<tabbed>:
