我正在尝试使用 ajax 和 php 在我的多个表中获取下一行。我的概念是,在更改我的年份和类型选择时,表必须重新出现。如果我将类型更改为第三年表隐藏并且学期第三表出现。它工作正常,。但是如果我改变没有年表行也必须根据它添加。例如,如果没有第 4 年意味着那么我必须在每个表中获得 4 行。我不知道我在这里袭击的地方?
我的代码:
<table>
<tr><td><label><span class="required">*</span>No of Year</label></td>
<td>
<select name="no_of_year" id="no_no_year" onchange="change_row()">
<option value="">--Year--</option>
<?php for($i=1;$i<=$year;$i++) { ?>
<option value="<?php echo $i; ?>" <?php if($_POST['no_of_year']==$i) { echo "selected"; } ?>><?php echo $i; ?></option>
<?php } ?>
</select> <span class="required"><?php echo $msg_year;?></span>
</td>
</tr>
<tr> <td><label><span class="required">*</span>Type</label> </td>
<td><select name="type" onchange="change_col(this.value);"><option value="">--Type--</option> <option value="2" <?php if($_POST['type']=='2') { echo "selected"; } ?>>Semester</option> <option value="1" <?php if($_POST['type']== '1') { echo "selected"; } ?>> Year </option> </select>
<span class="required"><?php echo $msg_type;?></span></td></tr>
<tr> <td><label><span class="required">*</span>Fees Per Year/Semester:</label> </td> </tr>

</table>
</td>
</tr>
</table>
</tr>
</table>
脚本:
<script type="text/javascript">
function change_col(type)
