问题描述
我有两个具有相同值的下拉框...当我在第一个下拉选择一个值时,第二个下拉必须隐藏所选的值并显示剩下的第二个下拉...我正在获取使用php从表中下拉值...这可能是通过设计或使用查询???
//第一次下拉
I have two Drop down boxes with the same values on both... when i choose a value in 1st drop down , the second drop down must hide the chosen value and display remaining in the second drop down...am fetching drop down values from a table using php ...is this possible via design or using a query???
//1st drop down
<td><i><b>Rec_Series</b></i></td>
<td><select id="rec" name="rec">
<?php Show_Recseries($_POST['Region'],$brname[0]) ; ?>
</select>
</td>
<script language="javascript">$('#rec').val("<?php echo $_POST['rec'];?>")</script>
//第二次下拉
//2nd drop down
<td><i><b>Bill_Mac_id</b></i></td>
<td><select id="brmacid" name="brmacid">
<?php
Show_Mac_id($_POST['Region'],$brname[0]);
?>
</select>
</td>
<script language="javascript">$('#brmacid').val("<?php echo $_POST['brmacid'];?>")</script>
有人可以帮我吗? []
