Question

令人惊讶的stackoverflows。我有一个表单，通过ajax执行动态表单值的计算。表单输入值被提交，而跨度div值没有。有人能帮我吗。感谢

<script type="text/javascript">
$(document).ready(function (e) {
    $("#orderForm").on('submit',(function(e) {

        e.preventDefault();

        $.ajax({

url: "order.php",

            type: "POST",

        data:  new FormData(this),
            contentType: false,
            cache: false,
            processData:false,
            success: function(data)
            {
            $("#target").html(data);
$('#alerts').delay(2000).fadeOut('slow');
            },
            error: function() 
            {
            }           
       });
    }));
});


</script>




<form method="post"  id="orderForm">
 price:<input  type="text" name="price[]"  value=""><br>
sum total:  <span id="sum">500</span>

</form>

Answer 1

除了跨度之外，尝试向表单添加隐藏的输入字段。像这样：

<form method="post"  id="orderForm">
   <input type="hidden" id="sum">
   price:<input  type="text" name="price[]"  value=""><br>
   sum total:  <span id="sum">500</span>
</form>

通过ajax传递动态表单值和span id值
