得到两个表的总数

Question

我这里有两个HTML表，用于计算每列的总数。

这是我的问题

我不知道如何获得两张桌子的总数。

当您更改单元格中的数字时，我希望显示表格，我希望在按键时重新计算总数。

还有任何想法如何简化我的JavaScript代码。

这是我的第一张桌子的代码。 请查看下面我的小提琴的链接以获取完整的代码。 谢谢。

    <table style="border:1px solid purple">

    <tr id = "Tr1">
        <td><input class="cell2" type="text" name="cell2" value="SAMPLE2" /></td>

Answer 1

我在<td>和<tr>添加了以下类

1. cell-val ：单元格包含一个值，该值是计算的一部分
2. cell-number ：单元格包含一个数字（原因：使单元格正确对齐）
3. cell-total ：单元格包含总计
4. cell-grand-total ：单元格包含总计
5. row-total ：行包含总值
6. row-grand-total ：行包含总计

我修改了calculateSum()函数。 其中，基于单元的索引执行计算。

计算所有cell-total

1. 获取td.cell-total的索引
2. 获取该索引中的所有上述单元格（ $(curTable).find("tr>td.cell-val:nth-child(" + indCell + ")") ））
3. totalCol =将以上所有单元格相加
4. 设置数据集中的总和以用于总计计算（ $(this).data('value', totalCol) ）
5. 设置cell-total = numberWithCommas(totalCol.toFixed(2))的html

在这里， numberWithCommas()将您的数字转换为逗号分隔的值，因为它使数字可读。

对总计进行类似的计算。

这是代码段：让我知道是否有任何问题

 $(document).ready(function() { $("input").keyup(function() { inputKeyUp(); calculateSum(); }); calculateSum(); inputKeyUp(); }); function inputKeyUp() { // TOTAL COST - 30s $("input[name='cell3']").each(function(index) { var cell3 = $("input[name='cell3']").eq(index).val(); var cell5 = $("input[name='cell5']").eq(index).val(); var cell6 = parseFloat(cell3) * parseFloat(cell5); if (cell3 == "") { cell6 = 0; } if (cell3 == "") { cell8 = 0; } else { var cell6 = parseFloat(cell3) * parseFloat(cell5); } if (!isNaN(cell6)) { $("input[name='cell6']").eq(index).val(cell6.toFixed(2)); } }); // TOTAL TARPs - 30s $("input[name='cell4']").each(function(index) { var cell4 = $("input[name='cell4']").eq(index).val(); var cell5 = $("input[name='cell5']").eq(index).val(); var cell7 = parseFloat(cell4) * parseFloat(cell5); if (cell4 == "") { cell7 = 0; } if (cell4 == "") { cell11 = 0; } else { var cell7 = parseFloat(cell4) * parseFloat(cell5); } if (!isNaN(cell7)) { $("input[name='cell7']").eq(index).val(cell7.toFixed(2)); } }); // COST/15s $("input[name='cell3']").each(function(index) { var cell3 = $("input[name='cell3']").eq(index).val(); var cell8 = parseFloat(cell3) * parseFloat(0.6); if (cell3 == "") { cell8 = 0; } else { var cell8 = parseFloat(cell3) * parseFloat(0.6); } if (!isNaN(cell8)) { $("input[name='cell8']").eq(index).val(cell8.toFixed(2)); } }); // TOTAL COST - 15s $("input[name='cell8']").each(function(index) { var cell8 = $("input[name='cell8']").eq(index).val(); var cell9 = $("input[name='cell9']").eq(index).val(); var cell10 = parseFloat(cell8) * parseFloat(cell9); if (cell9 == "") { cell10 = 0; } if (cell8 == "") { cell10 = 0; } else { var cell10 = parseFloat(cell8) * parseFloat(cell9); } if (!isNaN(cell10)) { $("input[name='cell10']").eq(index).val(cell10.toFixed(2)); } }); // TOTAL TARPs - 15s $("input[name='cell4']").each(function(index) { var cell4 = $("input[name='cell4']").eq(index).val(); var cell9 = $("input[name='cell9']").eq(index).val(); var cell11 = parseFloat(cell4) * parseFloat(cell9); if (cell9 == "") { cell11 = 0; } if (cell4 == "") { cell11 = 0; } else { var cell11 = parseFloat(cell4) * parseFloat(cell9); } if (!isNaN(cell11)) { $("input[name='cell11']").eq(index).val(cell11.toFixed(2)); } }); } function calculateSum() { $("table").each(function() { var curTable = this; $(this).find(".cell-total").each(function() { var indCell = ($(this).index() + 1), totalCol = 0, cellValue; $(curTable).find("tr>td.cell-val:nth-child(" + indCell + ")").each(function() { cellValue = parseFloat($(this).find("input").val()); totalCol += cellValue || 0; }); $(this).data('value', totalCol); $(this).html(numberWithCommas(totalCol.toFixed(2))); }); }); $("table tr.row-grand-total td.cell-grand-total").each(function() { var indCell = ($(this).index() + 1), totalCol = 0, cellValue; $("table tr.row-total>td:nth-child(" + indCell + ")").each(function() { cellValue = parseFloat($(this).data("value")); totalCol += cellValue || 0; }); $(this).find("div").html(numberWithCommas(totalCol.toFixed(2))); }); } function numberWithCommas(x) { return x.toString().replace(/\\B(?=(\\d{3})+(?!\\d))/g, ","); } 

 .cell-number, .cell-number input { text-align: right; } .row-grand-total { font-weight: bold; }

Answer 2

您不需要对您的手机ID进行硬编码。

如果您知道nth-child选择器和index（）方法，则可以轻松实现。

这是有效的解决方案。

 $(function() { $(document).on("keyup", "input[type='text']", function(event) { var $cell = $(event.target).parent(); var index = $cell.index() + 1; var $containerTable = $cell.closest("table"); var sum = 0; //iterate over the entire columns that you want to have total caluculated. $.each($("td:nth-child(" + index + ")", $containerTable), function(idx, cell) { sum += ($(cell).find("input").length) ? +($(cell).find("input").val()) : 0; }); //Once caculated, update the corresponding result cell on that table. $(".result td:eq(" + (index - 1) + ") div", $containerTable).html(sum); //Once result is calculated, update the grand total by iterating over the grand total cells. $.each($(".grand-result div"), function(idx, grCell) { var resultIndex = $(grCell).parent().index(); var grandSum = 0; $.each($(".result td:nth-child(" + (resultIndex + 1) + ")"), function(idx, resultCell) { grandSum += ($(resultCell).find("div").length) ? +($(resultCell).find("div").html()) : 0; }); $(grCell).text(grandSum); }); }); $("input[type='text']").trigger("keyup"); });

使用vanilla js获取所有输入值。 无需jQuery。 除非需要旧版浏览器支持？ 另外，您可能需要考虑将输入类型更改为“数字”。 这样，您可以减少必须执行的其他检查。

注意：我还没有将功能附加到'keyup'上，但是我确定您可以管理它：)

let fields = document.querySelectorAll('input');
let value = 0;

for (i = 0; i < fields.length; i++) {
  let itemVal = fields[i].value;
  if (!isNaN(itemVal) && itemVal != '') { // May need additional checks/regex to make sure value is a number
    console.log(itemVal)
    value = value + parseFloat(itemVal)

  } 
}

console.log(value)
