=head1 DESCRIPTION
|
|
|
|
A module modeled a bit after Rails' ActionView helpers. Several small
|
|
functions that create HTML tags from various kinds of data sources.
|
|
|
|
The C<id> attribute is usually calculated automatically. This can be
|
|
overridden by either specifying an C<id> attribute or by setting
|
|
C<no_id> to trueish.
|
|
|
|

Available high-level functions implemented in this module:
|
|
|
|
=over 4
|
|
|
|
=item C<yes_no_tag $name, $value, %attributes>
|
|
|
|
Creates a HTML 'select' tag with the two entries C<yes> and C<no> by
|
|
calling L<select_tag>. C<$value> determines
|
|
which entry is selected. The C<%attributes> are passed through to
|
|
L<select_tag>.
|
|
|
|
=item C<textarea_tag $name, $value, %attributes>
|
|
|
|
Creates a HTML 'textarea' tag named C<$name> with the content
|
|
C<$value> and with arbitrary HTML attributes from C<%attributes>. The
|
|
tag's C<id> defaults to C<name_to_id($name)>.
|
|
|
|
=item C<date_tag $name, $value, %attributes>
|
|
|
|
Creates a date input field, with an attached javascript that will open a
|
|
calendar on click.
|
|
|
|
=item C<javascript_tag $file1, $file2, $file3...>
|
|
|
|
Creates a HTML 'E<lt>script type="text/javascript" src="..."E<gt>'
|
|
tag for each file name parameter passed. Each file name will be
|
|
postfixed with '.js' if it isn't already and prefixed with 'js/' if it
|
|
doesn't contain a slash.
|
|
|
|
=item C<stylesheet_tag $file1, $file2, $file3...>
|
|
|
|
Creates a HTML 'E<lt>link rel="text/stylesheet" href="..."E<gt>' tag
|
|
for each file name parameter passed. Each file name will be postfixed
|
|
with '.css' if it isn't already and prefixed with 'css/' if it doesn't
|
|
contain a slash.
|
|
|
|
=item C<tabbed \@tab, %attributes>
|
|
|
|
Will create a tabbed area. The tabs should be created with the helper function
|
|
C<tab>. Example:
|
|
|
|
[% L.tabbed([
|
|
L.tab(LxERP.t8('Basic Data'), 'part/_main_tab.html'),
|
|
L.tab(LxERP.t8('Custom Variables'), 'part/_cvar_tab.html', if => SELF.display_cvar_tab),
|
|
]) %]
|
|
|
|
=item C<areainput_tag $name, $content, %PARAMS>
|
|
|
|
Creates a generic input tag or textarea tag, depending on content size. The
|
|
amount of desired rows must be either given with the C<rows> parameter or can
|
|
be computed from the value and the C<cols> paramter, Accepted parameters
|
|
include C<min_rows> for rendering a minimum of rows if a textarea is displayed.
|
|
|
|
You can force input by setting rows to 1, and you can force textarea by setting
|
|
rows to anything >1.
|
|
|
|
=item C<multiselect2side $id, %params>
|
|
|
|
Creates a JavaScript snippet calling the jQuery function
|
|
C<multiselect2side> on the select control with the ID C<$id>. The
|
|
select itself is not created. C<%params> can contain the following
|
|
entries:

|
|
|

|
|
|
|
=item C<labelsx>
|
|
|
|

|
|
translation of 'Available'.
|
|
|
|
=item C<labeldx>
|
|
|
|
The label of the list of selected options. Defaults to the
|
|
translation of 'Selected'.

=item C<sortable_element $selector, %params>
|
|
|
|
Makes the children of the DOM element C<$selector> (a jQuery selector)
|
|
sortable with the I<jQuery UI Selectable> library. The children can be
|
|
dragged & dropped around. After dropping an element an URL can be
|
|
postet to with the element IDs of the sorted children.
|
|
|
|
If this is used then the JavaScript file C<js/jquery-ui.js> must be
|
|
included manually as well as it isn't loaded via C<$::form-gt;header>.
|
|
|
|
C<%params> can contain the following entries:
|
|
|
|
=over 2
|
|
|
|
=item C<url>
|
|
|
|
The URL to POST an AJAX request to after a dragged element has been
|
|
dropped. The AJAX request's return value is ignored by default. If given then
|
|
C<$params{with}> must be given as well.
|
|
|
|
=item C<ajax_return>
|
|
|
|
If trueish then the AJAX request's return is accepted.
|
|
|
|
=item C<with>
|
|
|
|
A string that is interpreted as the prefix of the children's ID. Upon
|
|
POSTing the result each child whose ID starts with C<$params{with}> is
|
|
considered. The prefix and the following "_" is removed from the
|
|
ID. The remaining parts of the IDs of those children are posted as a
|
|
single array parameter. The array parameter's name is either
|
|
C<$params{as}> or, missing that, C<$params{with}>.
|
|
|
|
=item C<as>
|
|
|
|
Sets the POST parameter name for AJAX request after dropping an
|
|
element (see C<$params{with}>).
|
|
|
|
=item C<handle>
|
|
|
|
An optional jQuery selector specifying which part of the child element
|
|
is dragable. If the parameter is not given then it defaults to
|
|
C<.dragdrop> matching DOM elements with the class C<dragdrop>. If the
|
|
parameter is set and empty then the whole child element is dragable,
|
|
and clicks through to underlying elements like inputs or links might
|
|
not work.
|
|
|
|
=item C<dont_recolor>
|
|
|
|
If trueish then the children will not be recolored. The default is to
|
|
recolor the children by setting the class C<listrow0> on odd and
|
|
C<listrow1> on even entries.
|
|
|
|
=item C<params>
|
|
|
|
An optional JavaScript string that is evaluated before sending the
|
|
POST request. The result must be a string that is appended to the URL.

Example:
|
|
|
|
<script type="text/javascript" src="js/jquery-ui.js"></script>
|
|
|
|
<table id="thing_list">
|
|
<thead>
|
|
<tr><td>This</td><td>That</td></tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr id="thingy_2"><td>stuff</td><td>more stuff</td></tr>
|
|
<tr id="thingy_15"><td>stuff</td><td>more stuff</td></tr>
|
|
<tr id="thingy_6"><td>stuff</td><td>more stuff</td></tr>
|
|
</tbody>
|
|
<table>
|
|
|
|
[% L.sortable_element('#thing_list tbody',
|
|
url => 'controller.pl?action=SystemThings/reorder',
|
|
with => 'thingy',
|
|
as => 'thing_ids',
|
|
recolor_rows => 1) %]
|
|
|
|
After dropping e.g. the third element at the top of the list a POST
|
|
request would be made to the C<reorder> action of the C<SystemThings>
|
|
controller with a single parameter called C<thing_ids> -- an array
|
|
containing the values C<[ 6, 2, 15 ]>.
|
|
|
|
=item C<dump REF>
|
|
|
|
Dumps the Argument using L<Data::Dumper> into a E<lt>preE<gt> block.
|
|
|
|
=item C<sortable_table_header $by, %params>
|
|
|
|
Create a link and image suitable for placement in a table
|
|
header. C<$by> must be an index set up by the controller with
|
|
L<SL::Controller::Helper::make_sorted>.
|
|
|
|
The optional parameter C<$params{title}> can override the column title
|
|
displayed to the user. Otherwise the column title from the
|
|
controller's sort spec is used.
|
|
|
|
The other parameters in C<%params> are passed unmodified to the
|
|
underlying call to L<SL::Controller::Base::url_for>.
|
|
|
|
See the documentation of L<SL::Controller::Helper::Sorted> for an
|
|
overview and further usage instructions.
|
|
|
|
=item C<paginate_controls>
|
|
|
|
Create a set of links used to paginate a list view.
|
|
|
|
See the documentation of L<SL::Controller::Helper::Paginated> for an
|
|
overview and further usage instructions.

|
|
|
|
=item C<tab, description, target, %PARAMS>
|
|
|
|
Creates a tab for C<tabbed>. The description will be used as displayed name.
|
|
The target should be a block or template that can be processed. C<tab> supports
|
|
a C<method> parameter, which can override the process method to apply target.
|
|
C<method => 'raw'> will just include the given text as is. I was too lazy to
|
|
implement C<include> properly.
|
|
|
|
Also an C<if> attribute is supported, so that tabs can be suppressed based on
|
|
some occasion. In this case the supplied block won't even get processed, and
|
|
the resulting tab will get ignored by C<tabbed>:
|
|
|
|
L.tab('Awesome tab wih much info', '_much_info.html', if => SELF.wants_all)
|
|
|
|
=item C<truncate $text, [%params]>
|
|
|
|
See L<SL::Presenter::Text/truncate>.
|
|
|
|
=item C<simple_format $text>
|
|
|
|
See L<SL::Presenter::Text/simple_format>.
