Question

我目前在aproject工作，在管理员编辑价格时计算价格金额。我想在使用jquery编辑值时添加列值。请给我一些示例，当我编辑值时，如何实现对列值的求和。 http://jsfiddle.net/unKDk/13/

  <script type="text/javascript">
  var totals=[0,0,0];
  $(document).ready(function(){

  var $dataRows=$("#sum_table tr:not('.totalColumn, .titlerow')");
  alert("inside");
  $dataRows.each(function() {
    $(this).find('.rowDataSd').each(function(i){        
        totals[i]+=parseInt( $(this).html());
    });
  });
$("#sum_table td.totalCol").each(function(i){  
    $(this).html("total:"+totals[i]);
  });

 });

</script>



       <table id="sum_table" class="display" style="float:left; width: 100%;border-radius: 
       5px 5px 5px 5px;
                        box-shadow: 2px 2px 6px #666666;-moz-
    box-sizing: none;" border=1 data="${bidding}" >


                        <tr>
                        <th style="color:#3300CC;  align:center" colspan="14">Double-
                    </tr>
                        <tr>  
                            <td  class="heading">Bidding Id</td>

                    <c:forEach items="${biddings}" var="bidding" >
                        <tr>

                             <td>${bidding.itemName}</td>  
                             <td>${bidding.uom}</td>

            </table>

Answer 1

好的，我希望我能正确理解......

FIDDLE DEMO

HTML：

<tr>
    <td class="rowDataSd">Orange</td>
    <td class="rowDataSd">2</td>
    <td class="rowDataSd">
        <input name='amountInfo' value='5' />
    </td>
</tr>

jquery的一部分：

$('input[name="amountInfo"]').on('input', function () {
          total = 0;
          $dataRows.each(function () {
              var amountInfo = parseInt($(this).find('input[name="amountInfo"]').val());
              amountInfo = (amountInfo) ? amountInfo : 0; //Check if number otherwise set to 0
              total += amountInfo;
          });
          $('.totalCol').html("Total:" + total);
      });

基本上我会监听任何输入更改，然后检索每行的新值并更新总计。
