我有这个功能,我认为它显示了巨大的选择框......
function loadChild() {
$configmodel = gbimport ( "listbingo.model.configuration" );
$params = $configmodel->getParams ();
$adid = ( int ) JRequest::getVar ( 'adid', 0 );
$parent = ( int ) JRequest::getVar ( 'catparentid', 0 );
$selfid = ( int ) JRequest::getVar ( 'selfid', 0 );
if (! $parent) {
return false;
} else {
$catmodel = gbimport ( "listbingo.model.category" );
//$children = $catmodel->getParentTreeForSelect(true, $parent);
$cat_list = $catmodel->getParentTreeForSelect ( true, $parent );
$categories = array ();
$categories [] = JHTML::_ ( 'select.option', '', JText::_ ( 'SELECT_CATEGORY' ), 'value', 'text' );
foreach ( $cat_list as $cat ) {
$xtreename = str_replace ( ".", "", $cat->treename );
$xtreename = str_replace ( " ", "-", $xtreename );
$xtreename = str_replace ( "<sup>|_</sup>", "", $xtreename );
if ($cat->children > 0) {
$categories [] = JHTML::_ ( 'select.optgroup', JText::_ ( $xtreename ), 'value', 'text' );
} else {
$categories [] = JHTML::_ ( 'select.option', $cat->value, JText::_ ( $xtreename ), 'value', 'text' );
}
}
if((int)$adid>0)
{
$disarray = array ('class' => 'inputbox required', 'onChange' => 'processSubcat(this.value)','disabled'=>'disabled');
}
else
{
$disarray = array ('class' => 'inputbox required', 'onChange' => 'processSubcat(this.value)');
}
$subcats = JHTML::_ ( 'select.genericlist', $categories, 'scatid', $disarray, 'value', 'text', $selfid );
$view = $this->getView ( 'ajaxinput' );
$view->setLayout ( 'subcat' );
$view->assignRef ( 'subcats', $subcats );
$view->assignRef ( 'adid', $adid );
$view->assignRef ( 'selfid', $selfid );
$view->display ();
}
}
选择框看起来像这样:
<select name="scatid">
<optgroup label="June">
<option>2005</option>
<option>2006</option>
<option>2007</option>
<option>2008</option>
</optgroup>
<optgroup label="July">
<option>2005</option>
<option>2006</option>
</optgroup>
</select>
它有数百个选项(所有的 selctbox)和几十个 optgroups...
我想要实现的是在一个选择框中显示 optgroups ......以及在另一个选择框中显示所选 optgroup 的选项......
有人可以帮我解决这个问题...我不知道从什么开始...我不擅长 js/jquery...
我想要这样,因为有太多选项可供选择,我必须向下滚动很多才能找到我需要的东西......
非常感谢。
