使用javascript自动填充表单-从datalist获取数据

我有一个自动完成字段，它从数据库接收数据：

<datalist id="custlist">
    <?php
      $q_cust=mysql_query("select * from customer where rowstatus='0' order by id");          
                if (mysql_num_rows($q_cust)>0) {
                    while ($row=mysql_fetch_array($q_cust)){
                        print '<option value="'.$row['id'].'">'.$row['name'].'</option>';
                    }
                }

     ?>
 </datalist>

<tr>
    <td></td>
    <td><h3>Field 1</h3></td>
    <td>:</td>
    <td><input class="awesomplete" required="required" id="cust" name ="custnama" list="custlist" /></h3></td>
    <td></td>

</tr>
