select联动效果：

模版代码：

<dl>
    <dt>品牌：</dt>
    <dd>
        <select class="combox required" name="pinpai_id" ref="jixing_id"
            refUrl="{{$smarty.const.__ROOT__?c=jixing&a=getJixing&pinpai={value}|url}}">
            <option value="">所有品牌</option>
            {{html_options options=$pinpaiArr selected=$info.pinpai_id}}
        </select>
    </dd>
</dl>
<dl>
    <dt>机型：</dt>
    <dd>
        <select class="combox required" name="jixing_id" id="jixing_id">
        <option value="">所有机型</option>
        {{html_options options=$jixingArr selected=$info.jixing_id}}
        </select>
    </dd>

服务器端返回代码：

public function getJixingAction() {
    $pinpai = (int)$this->request('pinpai');
    $list = $this->cur_model->where('pinpai_id='.$pinpai)->order('id ASC')->select();
    $text = '[["", "所有机型"]';
    foreach ($list as $v) {
        $text .= ',["'.$v['id'].'", "'.$v['name'].'"]';
    }
    $text .= ']';
    exit($text);
