  随手一敲烂代码 哈哈哈  大概就是算差价再用jquery改变对应的内容
  var success=function(result){
      if(result.state==1){
          $(function () {
              //原来的总价
              var total =  parseInt($("#total").html());
              //得到那个小计
              var price =parseInt($("#newsum-"+product_id).html());
              //得到和之前的差价
              var sub=result.sum-price;
              //得到新的总价
              var newtotal=total+sub;
              $("#newsum-"+product_id).html(result.sum);
              //修改总价
              $("#total").html(newtotal);
          });

  第一 添加class  id
  

  <td align="center" bgcolor="#ffffff" >￥<span class="totle" id="total-<?php echo $product['id'] ?>"><?php echo $product['num']*$product['price'] ?></span>元</td>

  <td bgcolor="#ffffff">
             <span id="total2">购物金额小计 ￥<?php echo $total ?>元</span>             
   </td>

  第二 添加js

  if(response.errno == 0){
                              var price = ($("#product-"+productid).val())*($("#p-"+productid).html());
                              $("#total-"+productid).html(price);
                              var sum = 0;
                              $(".totle").each(function() {
                                sum += parseFloat($(this).text());
                              $("#total2").text("￥"+sum+"元");
        })
  }

         </dd>

  <script type="text/javascript">
          function changeNumber(){
                var num = parseInt($("#number").val());
                var sellPrice = <?php echo $data['price']?>;
                $("#totalPrice").html("￥"+num*sellPrice+"元");
          }
        </script>
