javascript - HTML 表格无法正确呈现

Question

我有一个包含 JSON 数据的 HTML 表，我正在做的是创建一列作为输入字段，我的表标题是 Code,Item Name,Unitcode、Quantity和AcceptedQty，其中我仅将接受数量设置为输入字段，但数量字段也会转换为输入字段，但我不这样做知道我做错了什么

var tableDataDraft = [{
    "Code": "1326",
    "Item Name": "PINEAPPLE KG",
    "Unitcode": "NOS",
    "Quantity": "3.00",
    "AcceptedQty": "3.00"
  },
  {
    "Code": "1494",
    "Item Name": "2D CAKE CHARGES PER KG",
    "Unitcode": "NOS",
    "Quantity": "3.00",
    "AcceptedQty": "3.00"
  }
]


function addTableDraft(tableDataDraft) {
  var col = Object.keys(tableDataDraft[0]);
  var countNum = col.filter(i => !isNaN(i)).length;
  var num = col.splice(0, countNum);
  col = col.concat(num);
  var table = document.createElement("table");
  var tr = table.insertRow(-1);
  for (var i = 0; i < col.length; i++) {
    var th = document.createElement("th");
    th.innerHTML = col[i];
    tr.appendChild(th);
    tr.classList.add("text-center");
    tr.classList.add("head")
  }
  for (var i = 0; i < tableDataDraft.length; i++) {
    tr = table.insertRow(-1);
    for (var j = 0; j < col.length; j++) {
      let tabCell = tr.insertCell(-1);
      var hiddenField = document.createElement("input"); //creating input field hidden
      hiddenField.style.display = "none";
      var tabledata = tableDataDraft[i][col[j]];
      if (tableDataDraft[i]['Code'] === tableDataDraft[i][col[j]]) { //now setting html attributes
        tabCell.innerHTML = tabledata;
        hiddenField.setAttribute('name', 'Item_Code');
        hiddenField.setAttribute('value', tabledata);
        tabCell.appendChild(hiddenField);
      }
      if (tableDataDraft[i]['Item Name'] === tableDataDraft[i][col[j]]) {
        tabCell.innerHTML = tabledata;
        hiddenField.setAttribute('name', 'Item_Name');
        hiddenField.setAttribute('value', tabledata);
        tabCell.appendChild(hiddenField);
      }
      if (tableDataDraft[i]['Unitcode'] === tableDataDraft[i][col[j]]) {
        tabCell.innerHTML = tabledata;
        hiddenField.setAttribute('name', 'Unit_code');
        hiddenField.setAttribute('value', tabledata);
        tabCell.appendChild(hiddenField);
      }
      if (tableDataDraft[i]['Quantity'] === tableDataDraft[i][col[j]]) { //this quantity field i don't want to be input field

        hiddenField.setAttribute('name', 'Quantity');
        hiddenField.setAttribute('value', tabledata);
        tabCell.appendChild(hiddenField);
      }
      if (tableDataDraft[i]['AcceptedQty'] === tableDataDraft[i][col[j]]) { //this one i want to be a input field

        var quantityField = document.createElement("input");
        quantityField.style.border = "none";
        quantityField.style["text-align"] = "right";
        quantityField.setAttribute("name", "AcceptedQty");
        quantityField.setAttribute("autocomplete", "on");
        quantityField.setAttribute("value", tabledata);
        quantityField.setAttribute("type", "tel");
        quantityField.setAttribute("required", "required");
        quantityField.classList.add("dataReset");
        quantityField.toLocaleString('en-IN');
        tabCell.appendChild(quantityField);
      }

      if (j > 1)
        tabCell.classList.add("text-right");
    }
  }
  var divContainer = document.getElementById("table");
  divContainer.innerHTML = "";
  divContainer.appendChild(table);
  table.classList.add("table");
  table.classList.add("table-striped");
  table.classList.add("table-bordered");
  table.classList.add("table-hover");

为什么数量字段也显示为输入字段，我不知道

由于我的代码有点长，因为我添加了 HTML 表单 Attributes 因为我希望将所有数据发送到我的后端，所以我在 ajax 调用时序列化我的表单

我已经注释了我正在做什么的所有行，以便大家更容易理解

Answer 1

问题是因为在每行插入值时，您比较的是列值而不是列名称。当值相同时，这会导致问题，例如 Quantity 和 AcceptedQty 具有相同的值 3.0。尝试将其更改为 4.0，您会发现它有效。

这是代码的简化版本，用于检查当前列是否为 AcceptedQty 并仅显示一个输入字段。您仍然可以使用其他 if block ，但请确保条件类似于 if (col[j] === 'Code') 或 (col[ j] === '数量') 等

var tableDataDraft = [{
    "Code": "1326",
    "Item Name": "PINEAPPLE KG",
    "Unitcode": "NOS",
    "Quantity": "3.00",
    "AcceptedQty": "3.00"
  },
  {
    "Code": "1494",
    "Item Name": "2D CAKE CHARGES PER KG",
    "Unitcode": "NOS",
    "Quantity": "3.00",
    "AcceptedQty": "3.00"
  }
]


function addTableDraft(tableDataDraft) {
  var col = Object.keys(tableDataDraft[0]);
  var countNum = col.filter(i => !isNaN(i)).length;
  var num = col.splice(0, countNum);
  col = col.concat(num);
  var table = document.createElement("table");
  var tr = table.insertRow(-1);
  for (var i = 0; i < col.length; i++) {
    var th = document.createElement("th");
    th.innerHTML = col[i];
    tr.appendChild(th);
    tr.classList.add("text-center");
    tr.classList.add("head")
  }
  for (var i = 0; i < tableDataDraft.length; i++) {
    tr = table.insertRow(-1);
    for (var j = 0; j < col.length; j++) {
      let tabCell = tr.insertCell(-1);
      var hiddenField = document.createElement("input"); //creating input field hidden
      hiddenField.style.display = "none";
      var tabledata = tableDataDraft[i][col[j]];
      if (col[j] === 'AcceptedQty') { 
      //this one i want to be a input field
        
        var quantityField = document.createElement("input");
        quantityField.style.border = "none";
        quantityField.style["text-align"] = "right";
        quantityField.setAttribute("name", "AcceptedQty");
        quantityField.setAttribute("autocomplete", "on");
        quantityField.setAttribute("value", tabledata);
        quantityField.setAttribute("type", "tel");
        quantityField.setAttribute("required", "required");
        quantityField.classList.add("dataReset");
        quantityField.toLocaleString('en-IN');
        tabCell.appendChild(quantityField);
      }
      else
       { //now setting html attributes
        tabCell.innerHTML = tabledata;
        hiddenField.setAttribute('name', 'Item_Code');
        hiddenField.setAttribute('value', tabledata);
        tabCell.appendChild(hiddenField);
      }
      
      if (j > 1)
        tabCell.classList.add("text-right");
    }
  }
  var divContainer = document.getElementById("table");
  divContainer.innerHTML = "";
  divContainer.appendChild(table);
  table.classList.add("table");
  table.classList.add("table-striped");
  table.classList.add("table-bordered");
  table.classList.add("table-hover");
