我有下表使用 Javascript 来计算单元格的总和。当输入 Javascript 时,总数量相加并将其显示在 TD id="totalSum" 中。
最终我需要在totalSum等于100时将它放在哪里,然后执行php代码。
如何让 PHP 读取 totalSum 中的数据,然后在等于 100 时执行 PHP?
HTML-
<table id="mytable" width="394">
<colgroup>
<col style="width: 50px;">
<col>
<col style="width: 60px;">
<col style="width: 110px;">
</colgroup>
<tbody>
<tr>
<th width="130" height="43"></th>
<th width="52">Weight Select</th>
<th width="181">New P</th>
</tr>
<tr>
<td align="center" width="130"> </td>
<td align="center">
<input type="text" size="2" value="1" id="qty_item_1" name="sum" >
</td>
<td align="center" id="total_item_1"></td>
</tr>
<tr>
<td align="center" width="130"></td>
<td align="center" >
<input type="text" size="2" value="1" id="qty_item_2" name="sum" >
</td>
<td align="center" id="total_item_2"></td>
</tr>
<tr class="tr">
<td align="left" colspan="1"><strong>Grand Total:</strong></td>
<td width="11" align="left" id="totalSum"></td>
</tr>
</tbody>
</table>
Javascript-
<script type="text/javascript">
var bIsFirebugReady = (!!window.console && !!window.console.log);
