使用循环生成表行时自动将行和列数据添加在一起

Question

我正在创建一个表格，其中列和行应自动添加其数据，但是我必须基于数据库数据生成名称，并且必须使用循环来添加详细信息。添加列是完美的，但是在这里添加行是相当困难的：）

  

如何通过一个输入数据将行和列加在一起？并添加最后一列总计（不可修改）

注意：我的输入行将使用循环功能生成，因此，如果要更改class-name，id等，请在两个表行中进行更改。

对不起，我的英语不好，谢谢。您可以在下面找到以下代码段：

$(document).on('input', '.outstanding, .received, .paid', updateSchedule26);

function updateSchedule26() {
  var sum = 0, sum2 = 0, sum3 = 0, out, reci, paid;
  $('.outstanding, .received, .paid').each(function(i) {
    if (!isNaN(this.value) && this.value.length != 0) {
      if ($(this).hasClass('outstanding')) {
        out = $(this).val();
        sum += parseFloat(this.value);
      } else if($(this).hasClass('received')) {
        reci = $(this).val();
        sum2 += parseFloat(this.value);
      } else if($(this).hasClass('paid')) {
        paid = $(this).val()
        sum3 += parseFloat(this.value);
      }
    }
  });
  var total = (parseInt(out) + parseInt(reci)) + parseInt(paid);
  $(".amtOutstanding").val(parseFloat(total).toFixed(2));
  $('#sch26_outstanding').val(sum.toFixed(2));
  $('#sch26_received').val(sum2.toFixed(2));
  $('#sch26_paid').val(sum3.toFixed(2));
  $('#sch26_amtOutstanding').val($(".amtOutstanding").val());
}

我想您可以单独更新行和列，如下所示：

$(document).on('input', '.outstanding, .received, .paid', updateTable);

function updateTable() {
  updateRow($(this).closest("tr"));
  updateCol($(this).closest("td"), $(this));
  updateTotal($(this.closest("table")));
}

function updateRow($row) {
  var sum = 0,
    sum2 = 0,
    sum3 = 0;
  $row.find('.outstanding, .received, .paid').each(function(i) {
    if (!isNaN(this.value) && this.value.length != 0) {
      if ($(this).hasClass('outstanding')) {
        out = $(this).val();
        sum += parseFloat(this.value);
      } else if ($(this).hasClass('received')) {
        reci = $(this).val();
        sum2 += parseFloat(this.value);
      } else if ($(this).hasClass('paid')) {
        paid = $(this).val()
        sum3 += parseFloat(this.value);
      }
    }
  });
  $row.find('.amtOutstanding').val(sum + sum2 + sum3);
}

function updateCol($col, $input) {
  var index = $col.index() + 1;
  var sum = 0;
  $col.closest('table').find('td:nth-child(' + index + ')').find('input').each(function(i) {
    if (!isNaN(this.value) && this.value.length != 0 && !$(this).attr('id')) {
      sum += parseFloat(this.value);
    }
  });

  if ($input.hasClass('outstanding')) {
    $('#sch26_outstanding').val(sum.toFixed(2));
  } else if ($input.hasClass('received')) {
    $('#sch26_received').val(sum.toFixed(2));
  } else if ($input.hasClass('paid')) {
    $('#sch26_paid').val(sum.toFixed(2));
  } else if ($input.hasClass('amtOutstanding')) {
    $('#sch26_amtOutstanding').val(sum.toFixed(2));
  }

}

function updateSchedule26() {
  var sum = 0,
    sum2 = 0,
    sum3 = 0,
    out, reci, paid;
  $('.outstanding, .received, .paid').each(function(i) {
    if (!isNaN(this.value) && this.value.length != 0) {
      if ($(this).hasClass('outstanding')) {
        out = $(this).val();
        sum += parseFloat(this.value);
      } else if ($(this).hasClass('received')) {
        reci = $(this).val();
        sum2 += parseFloat(this.value);
      } else if ($(this).hasClass('paid')) {
        paid = $(this).val()
        sum3 += parseFloat(this.value);
      }
    }
  });
  var total = (parseInt(out) + parseInt(reci)) + parseInt(paid);
  $(".amtOutstanding").val(parseFloat(total).toFixed(2));
  $('#sch26_outstanding').val(sum.toFixed(2));
  $('#sch26_received').val(sum2.toFixed(2));
  $('#sch26_paid').val(sum3.toFixed(2));
}

function updateTotal($table) {
  var sum = 0;
  $table.find('.amtOutstanding').each(function(i) {
    if (!isNaN(this.value) && this.value.length != 0) {
        sum += parseFloat(this.value);
    }
  });
  $('#sch26_amtOutstanding').val(sum.toFixed(2))
}
