Jquery表行计算,多行/列

时间:2017-12-21 15:13:59

标签: javascript jquery

我有一张桌子,第一排代表几个月。接下来是价值观。我不想介绍聚合/行计算方法并将其显示在最后一行。由于行数和列数, 我不太确定从哪里开始 ,而不是重复代码。 因此我正在寻找一些提示开始

我为你准备了一个mcve,看看它看起来如何https://jsfiddle.net/468bguu1/2/

公式是

第1个月的计算ROW为:(.inc_row_0 + .inc_row_kor_0) - (.exp_row_0 + .exp_row_kor_0 + .work_row_0)

为方便计算,我添加了类名,我认为应该如何完成。

我的尝试:(首先必须将文本规范化为浮点数)

     for (var i = 0; i < 12; i++) {
   var row_a = parseFloat($(".inc_row_" + i).text().replace(/ /g, '').replace(',', '.')) + parseFloat($(".inc_row_kor_" + i).text().replace(/ /g, '').replace(',', '.'));
   var row_b = parseFloat($(".exp_row_" + i).text().replace(/ /g, '').replace(',', '.')) + parseFloat($(".exp_row_kor_" + i).text().replace(/ /g, '').replace(',', '.')) + parseFloat($(".work_row_" + i).text().replace(/ /g, '').replace(',', '.'));
   var calc = row_a - row_b;

   $(".res_row_" + i).text(calc.toFixed(2));
 }

2 个答案:

答案 0 :(得分:0)

这些取决于行单元格数量与所选择的相等。 整个&#34;从选择器开始#34;对于每个&#34;组&#34;单一班级会更好项目,使选择器更简单,更快速,更容易维护,但我不负责你的布局,只是一个建议。

首先,这是一个非常详细的选项,用于说明如何使用一组包含数据的数组。这可能会随着表的更改而出现问题,或者如果其中一个表&#34; row&#34;事情缺失或有额外的td可能不是很好。

&#13;
&#13;
function parseLocalString(localstring) {
  var strippedstring = localstring.replace(/ /g, '').replace(',', '.');
  var localnumber = parseFloat(strippedstring);
  return localnumber;
}
var myObj = {
  data: {}
}; // hold stuff without a lot of globals
myObj.data = {
  // arrays of numbers
  incRow: [],
  incRowKor: [],
  expRow: [],
  expRowKor: [],
  workRow: [],
  resRow: [],
};
// avoid the fixed 12, just get the stuff
// begins with
$("td[class^='inc_row_']").filter(function() {
  return !$(this).is("td[class^='inc_row_kor_']");
}).each(function() {
  myObj.data.incRow.push(parseLocalString($(this).text()));
});
$("td[class^='inc_row_kor_']").each(function() {
  myObj.data.incRowKor.push(parseLocalString($(this).text()));
});

$("td[class^='exp_row_']").filter(function() {
  return !$(this).is("td[class^='exp_row_kor_']");
}).each(function() {
  myObj.data.expRow.push(parseLocalString($(this).text()));
});
$("td[class^='exp_row_kor_']").each(function() {
  myObj.data.expRowKor.push(parseLocalString($(this).text()));
});

$("td[class^='work_row_']").each(function() {
  myObj.data.workRow.push(parseLocalString($(this).text()));
});

// calculate stuff
for (var i = 0; i < myObj.data.incRow.length; i++) {
  var row_a = myObj.data.incRow[i] + myObj.data.incRowKor[i];
  var row_b = myObj.data.expRow[i] + myObj.data.expRowKor[i] +
  myObj.data.workRow[i];
  var calc = row_a - row_b;
  myObj.data.resRow.push(calc);
}
console.log(myObj.data);
// display results
// odd the 'th' here...
$("th[class^='res_row_']").each(function(index,element) {
console.log(index,myObj.data.resRow[index].toFixed(2));
  $(this).text(myObj.data.resRow[index].toFixed(2));
});

&#13;

答案 1 :(得分:-1)

使用<tr>的ID(动态)

首先,您需要知道要使用哪一行,为每个行添加一个ID:
<tr class="btn-primary bg-success" id="inc_tr">
之后,您可以使用jQuery .each()函数(使用$(this)来处理每个<td>):

$("tr#inc_tr").each(function(trIndex) {
  $("td", this).each(function(tdIndex) {
    console.log($(this).text());
  });
});

并且不要忘记删除第一个(或#34;标题&#34;)。

<小时/> 使用<td> s id / class(静态)循环

你也可以使用循环。只需要在每个<td>的id后使其与索引一起使用,但您需要一个静态值:

for(var id = 0; id<=11; id++){
    console.log($(".inc_row_"+id).text());
}

由于它们是唯一标记,如果您使用id,而不是class,则会更好:

<td id="inc_row_0">0,00</td>

循环:

for(var id = 0; id<=11; id++){
    console.log($("#inc_row_"+id).text());
}

使用列

在这里你可以使用类,但我建议你为列中的每个单元格设置相同的类:

<tr class="btn-primary bg-success">
  <td>ROW A Σ</td>
  <td class="inc_col_0">0,00</td>
    ...
<tr class="btn-primary bg-success">
  <td>ROW A Adjust</td>
  <td class="inc_col_0">0,00</td>

现在,您可以再次执行.each()功能,并搜索<tr>的课程:

$("tr").each(function( indexTr ) {
  console.log($(this).find('td.inc_col_0').text());
});

或者,你可以试试:eq(),这个会返回第(x + 1)列。第二列的示例:

$("tr").each(function( indexTr ) {
  console.log($(this).find('td:eq(1)').text());
});
