修改前请先备份下列档案：
    themes/模板名称/flow.dwt
    flow.php

开启 themes/模板名称/flow.dwt

搜寻
  1. name="goods_number[{$goods.rec_id}]"
复制代码
会找到类似这段... (依据个人使用的模组不同会有些许差异)
  1. <input class="TextInput" name="goods_number[{$goods.rec_id}]" id="goods_number_{$goods.rec_id}" value="{$goods.goods_number}" type="text" size="4" onkeydown="showdiv(this)"/>
复制代码
置换成... (依据个人使用的模组不同会有些许差异)
  1. <input class="TextInput" onblur="changePrice(document.getElementById('goods_number_{$goods.rec_id}').value,{$goods.rec_id})" name="goods_number[{$goods.rec_id}]" id="goods_number_{$goods.rec_id}" value="{$goods.goods_number}" size="4" id="ECS_FORMBUY">
复制代码
搜寻
  1. <!-- {if $step eq "cart"} -->
复制代码
在下面加入
  1. <script type="text/javascript">
  2. /**
  3. * 点选可选属性或改变数量时修改商品价格的函数
  4. */
  5. function changePrice(number,rec_id)
  6. {
  7. //var attr = getSelectedAttributes(document.forms['ECS_FORMBUY']);
  8. // var qty = document.forms['ECS_FORMBUY'].elements['number'].value;
  9. Ajax.call('flow.php', 'step=update_cart_ajax&rec_id=' + rec_id +'&number=' + number, changePriceResponse, 'GET', 'JSON');
  10. }
  11. /**
  12. * 接收返回的信息
  13. */
  14. function changePriceResponse(res)
  15. {
  16. document.getElementById('goods_number_' + res.rec_id).value = res.goods_number;
  17. if (res.error > 0)
  18. {
  19. alert(res.content);
  20. }
  21. else
  22. {
  23. document.getElementById('subtotal_'+res.rec_id).innerHTML = res.subtotal;//商品小计
  24. document.getElementById('cart_amount_desc').innerHTML = res.cart_amount_desc;//购物车商品总价说明
  25. document.getElementById('market_amount_desc').innerHTML = res.market_amount_desc;//购物车商品总市价说明

  27. //更新购物车区块 (若你的购物流程页面没有包含 {insert name='cart_info'} 的话，则不需要放这段)
  28. //var cartInfo = document.getElementById('ECS_CARTINFO');
  29. //if (cartInfo)
  30. //{
  31.   //cartInfo.innerHTML = res.content;
  32. //}

  34. }
  35. }
  36. </script>

搜寻
  1. {$goods.subtotal}
复制代码
替换为
  1. <div id="subtotal_{$goods.rec_id}">{$goods.subtotal}</div>

复制代码
替换为
  1. <span id="cart_amount_desc">{$shopping_money}</span>

复制代码
将上面整段移除

搜寻
