bootstrap 弹出式搜索模板

研读了一下JA的代码

    <?php if ($this->countModules('head-search')) : ?>
                        <!-- HEAD SEARCH --><!-- $this->_c('head-search')是什么？？？$this->p又是什么？？ -->
                        <div class="head-search <?php $this->_c('head-search') ?>">
                            <div class="dropdown">
                                <!-- button 里面怎么会自动加aria-expanded = ture? 是bootstrap模板，上一个元素会增加一个 open属性？ -->
                              <button class="btn btn-primary dropdown-toggle" type="button" id="head-search" data-toggle="dropdown">
                                <i class="fa fa-search"></i>
                              </button>
                              <div class="dropdown-menu" role="menu" aria-labelledby="head-search">
                                  <!--直接调用模块moudules/mod_finder 注意后台的新建搜索模块有两种，一个是简单的search,另一个是smart search,后都对应是的mod_finder目录-->
                                <jdoc:include type="modules" name="<?php $this->_p('head-search') ?>" style="raw" />

                              </div>
                            </div>
                        </div>
                        <!-- //HEAD SEARCH -->
                        <!-- 总结，这个一个弹出式的Bootstrap模板，利用button自动添加属性aria-expanded = ture,button的父标签就自动增加open，它的下一级元素必须是dropdown-menu -->
                    <?php endif ?>

改写一个弹出式搜索比较简单，重写mod_finder模块的模板放在模板目录下的html/mod_finder/

在后台搜索模块下选相应layout

    <div class="dropdown">
        <button class="btn btn-primary dropdown-toggle" type="button" id="head-search" data-toggle="dropdown">
            <i class="fa fa-search"></i>
        </button>
        <div class="dropdown-menu" role="menu" aria-labelledby="head-search">
　　　　　　　　//上面是添加的代码
            <form id="mod-finder-searchform<?php echo $module->id; ?>" action="<?php echo JRoute::_($route); ?>" method="get" class="form-search">
                <div class="finder<?php echo $suffix; ?>">
                    <?php
                    // Show the form fields.
                    echo $output;
                    ?>

                    <?php $show_advanced = $params->get('show_advanced', 0); ?>
                    <?php if ($show_advanced == 2) : ?>
                        <br />
                        <a href="<?php echo JRoute::_($route); ?>"><?php echo JText::_('COM_FINDER_ADVANCED_SEARCH'); ?></a>
                    <?php elseif ($show_advanced == 1) : ?>
                        <div id="mod-finder-advanced<?php echo $module->id; ?>">
                            <?php echo JHtml::_('filter.select', $query, $params); ?>
                        </div>
                    <?php endif; ?>
                    <?php echo modFinderHelper::getGetFields($route, (int) $params->get('set_itemid', 0)); ?>
                </div>
            </form>
        </div>
    </div>
