之前,我有一个带有单选按钮的表单,当然,按下提交时它会在单选按钮中提交值.

但如果我不再需要收音机按钮,我该怎么办呢？当按表格单元格或行时会自动将值提交到下一页而不提交按钮？

<form method="post" action="billing.php">
    <table width="900" border="0" align="center" cellpadding="2" cellspacing="0" id='center'>
        <tr>
            <td><input type="radio" name="carrier" <?php if (isset($carrier) && $carrier=="LBC") echo "checked";?>  value="LBC"></td>
            <td><img src="../paymentoptions/LBC.jpg" alt="LBC" class="picture"/></td>
            <td><p>The Shipping takes 1-2 days for NCR and 2-3 days for any provincial. Payment method only available is through BPI Bank Deposit<p>
                <div id='price'> Additional ?250 </div></td>

        </tr>
        <tr>
            <td><input type="radio" name="carrier" <?php if (isset($carrier) && $carrier=="PickUp") echo "checked";?>  value="PickUp"></td>
            <td><img src="../paymentoptions/Pick-up.jpg" alt="Pick-Up" class="picture"/></td>
            <td><p>Personally pick up your merchandise at our office. …

<tr>
    <td height="250px" width="300px"><center><label><input type="radio" name="carrier" <?php if (isset($carrier) && $carrier=="LBC") echo "checked";?>  value="LBC"><img src="../paymentoptions/lbc.png" alt="LBC" class="picture" width="245px" style="margin:10px"/></label></td>

    <td height="250px" width="300px"><center><label><input type="radio" name="carrier" <?php if (isset($carrier) && $carrier=="PickUp") echo "checked";?>  value="PickUp"><img src="../paymentoptions/pickup.jpg" alt="Pick-Up" class="picture" height="210px" width="250px" style="margin:10px"/></label></td>
</tr>

您好,如果没有选择选项,如何禁用表单提交按钮？谢谢
