Question

我在html中创建一个表格，我必须在折扣后计算价格。我目前有2行7个标题单元格，在每个标题单元格下面我有一个单元格。我正在努力为我的细胞增加价值。我尝试了这个var cells = document.getElementById('table').getElementsByTagName('td'); cells[1] = "3";将值3添加到我的数量，但该值没有出现在我的桌子上。我想这样做，所以我可以稍后将转换功能应用到我的所有TDS。我做错了什么？

＆＃13;

/* Format amount */
function ConvertAmount(Amount) {
  var cells = document.getElementById('table').getElementsByTagName('td');
  cells[1] = "3";

  var Zahl = Amount;
  Zahl = Math.round(Zahl * Math.pow(10, 2)) / Math.pow(10, 2);
  Zahl = Zahl.toFixed(2);
  Zahl = Zahl.toString();

  var Negativ = false;
  if (Zahl.indexOf("-") == 0) {
    Negativ = true;
    Zahl = Zahl.replace("-", "");
  }

  var str = Zahl.toString();
  str = str.replace(".", ",");

 
  var intVorkommastellen = str.length - (str.length - str.indexOf(","));

  var intKTrenner = Math.floor((intVorkommastellen - 1) / 3);
 
  var intZiffern = (intVorkommastellen % 3 == 0) ? 3 : (intVorkommastellen % 3);

 
  strNew = str.substring(0, intZiffern);
  
  strHelp = str.substr(intZiffern, (str.length - intZiffern));

  
  for (var i = 0; i < intKTrenner; i++) {
    
    strNew += "." + strHelp.substring(0, 3);
   
    strHelp = strHelp.substr(intZiffern, (strHelp.length - intZiffern));
  }

 
  var szNachkommastellen = str.substring(intVorkommastellen, str.length);
  if (szNachkommastellen.length < 3) {
    strNew += str.substring(intVorkommastellen, str.length) + '0';
  } else {
    strNew += str.substring(intVorkommastellen, str.length);
  }
  var Zahl = strNew;

  if (Negativ) {
    Zahl = "- " + Zahl;
  }

  return Zahl;
}
