根据订单

Question

我在Virtuemart 3购物车中有一个奇怪的行为，我想了解并解决。

关于以下代码：

<input type="text"
                   onblur="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                   onclick="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                   onchange="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                   onsubmit="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                   title="<?php echo  vmText::_('COM_VIRTUEMART_CART_UPDATE') ?>" class="quantity-input js-recalculate" size="3" maxlength="4" name="quantity[<?php echo $pkey; ?>]" value="<?php echo $prow->quantity ?>" />

<button type="submit" class="vmicon vm2-add_quantity_cart sprite" name="updatecart.<?php echo $pkey ?>" title="<?php echo  vmText::_ ('COM_VIRTUEMART_CART_UPDATE') ?>" ></button>

<button type="submit" class="vmicon vm2-remove_from_cart" name="delete.<?php echo $pkey ?>" title="<?php echo vmText::_ ('COM_VIRTUEMART_CART_DELETE') ?>" ><span class="delBut">x</span><?php echo vmText::_ ('COM_VIRTUEMART_CART_DELETE') ?></button>

当有人在文本字段中输入不同的金额并点击＆＃34;输入＆＃34; /＆＃34;返回＆＃34;产品数量更新完全没问题。但是，如果我按照以下代码切换两个按钮，并且客户点击＆＃34;输入＆＃34; /＆＃34;返回＆＃34;金额已更新，但顶级产品也会从购物车中删除。

<input type="text"
                       onblur="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                       onclick="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                       onchange="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                       onsubmit="Virtuemart.checkQuantity(this,<?php echo $step?>,'<?php echo vmText::_ ('COM_VIRTUEMART_WRONG_AMOUNT_ADDED',true)?>');"
                       title="<?php echo  vmText::_('COM_VIRTUEMART_CART_UPDATE') ?>" class="quantity-input js-recalculate" size="3" maxlength="4" name="quantity[<?php echo $pkey; ?>]" value="<?php echo $prow->quantity ?>" />

<button type="submit" class="vmicon vm2-remove_from_cart" name="delete.<?php echo $pkey ?>" title="<?php echo vmText::_ ('COM_VIRTUEMART_CART_DELETE') ?>" ><span class="delBut">x</span><?php echo vmText::_ ('COM_VIRTUEMART_CART_DELETE') ?></button>

<button type="submit" class="vmicon vm2-add_quantity_cart sprite" name="updatecart.<?php echo $pkey ?>" title="<?php echo  vmText::_ ('COM_VIRTUEMART_CART_UPDATE') ?>" ></button>

我想知道为什么会发生这种情况，因为在第二个版本中似乎都会执行提交按钮。没有Java Script，是否有充分的解决方案。
