Question

我有一个HTML表格，里面有输入字段，我的表格由4列组成，我只需要在UI上显示3列，第四列用于其他工作，所以我不想显示它在UI

上

在我的代码中，我有四列Item Code Item Name Selling Price和quantity
我正在尝试将Selling Price列隐藏为标题
我已经隐藏了身体部位，但是在隐藏标题时遇到了问题

var tableData = [{
    "Item Code": "1001",
    "Item Name": "Beverages",
    "Selling Price": "65",
    "Quantity": "12"

  },
  {
    "Item Code": "2003",
    "Item Name": "Juices",
    "Selling Price": "75",
    "Quantity": "14"
  },
  {
    "Item Code": "1004",
    "Item Name": "Soups",
    "Selling Price": "689",
    "Quantity": "15"

Answer 1

没有CSS的解决方案：您可以使用此行从DOM中删除元素：

table.rows[i].removeChild(childNode);

或：

childNode.style = 'display: none'

保留元素但不显示。

var tableData = [{
    "Item Code": "1001",
    "Item Name": "Beverages",
    "Selling Price": "65",
    "Quantity": "12"

  {
    "Item Code": "2003",
    "Item Name": "Juices",
    "Selling Price": "75",
    "Quantity": "14"
  },
  {
    "Item Code": "1004",
    "Item Name": "Soups",
    "Selling Price": "689",
    "Quantity": "15"

  },
  {
    "Item Code": "2005",
    "Item Name": "Cookies",
    "Selling Price": "74",
    "Quantity": "17"

  },

     const childNode = table.rows[i].childNodes[index - 1];
     //childNode.style = 'display: none'

使用CSS解决方案：

table tr th:nth-child(3),
table tr td:nth-child(3){
 display: none;
}

Answer 2

您可以使用CSS

td:nth-child(3),th:nth-child(3){
  display: none;
}

var tableData = [{
    "Item Code": "1001",

    "Selling Price": "65",
    "Quantity": "12"

    "Item Code": "2003",
    "Item Name": "Juices",
    "Selling Price": "75",
    "Quantity": "14"
  },
  {
    "Item Code": "1004",
    "Item Name": "Soups",
    "Selling Price": "689",

Answer 3

您已经包含了JQuery，为什么不使用它-

$('#HourlysalesSummary td:nth-child(' + idx + '),#HourlysalesSummary th:nth-child(' + idx + ')').hide();

您可以将idx替换为列索引。列索引将从1开始。此代码将隐藏标题行和数据行。

要显示一列，只需使用.show()而不是.hide()

$('#HourlysalesSummary td:nth-child(' + idx + '),#HourlysalesSummary th:nth-child(' + idx + ')').show();

这只会隐藏列，而不会从DOM中删除，因此您仍然可以使用数据以防其他用途。
