根據選擇下拉框的內容和下面的內容篩選出想要的內容
<select class="select01" onchange="usuxx(this.value)"> {php $field = dr_field_options('chelei',0, 'case');} {loop $field $i $t} <option {if $i==$get.chelei}selected{/if} value="{$i}"> {$t} </option> {/loop} </select> <script> function usuxx(v) { var url = "{dr_search_url($params, 'chelei', 'usuxx', null,'case')}"; window.location.href = url.replace('usuxx', v); } </script>我不知道你字段到底是chelei還是ceshi，我就猜測是chelei吧
