我正在尝试使用 HTML 创建一个简单的维修表单，使用下拉列表我希望能够选择一个模型，然后在两个表中显示所有兼容零件，一个用于新零件，一个用于报废。目前，我在进行演示时正在将数据硬编码到 JavaScript 中。我遇到的问题是零件表除了标题之外没有显示任何内容。我错过了什么？

最初，我尝试创建 CSV 文件来控制数据，但没有成功。我还需要它在本地工作，而不是在 Web 服务器上。

您将 brand-1 作为模型下拉列表中的值传递给 item[0]，将其更改为 item[2]它代表模型。我建议您在顶部添加一个空白选项，例如“选择模型”，以便在页面加载时默认不选择任何选项。 不要在段落之外使用
。请停止使用 var，使用 const 或 let。如果数据将被更改，则使用 let，对于固定数据，请使用 const。

// SKU data
let skuData = [
  ["SKU1", "Description 1", "Value 1"],
  ["SKU2", "Description 2", "Value 2"],
  ["SKU3", "Description 3", "Value 3"]
];

// Model data
let modelData = [
  ["Brand 1", "Gen 1", "Model 1"],
  ["Brand 2", "Gen 2", "Model 2"],
  ["Brand 3", "Gen 3", "Model 3"]
];

// New parts data
let newPartsData = [
  ["Part 1", "10", "5", "Model 1,Model 2"],
  ["Part 2", "20", "3", "Model 1,Model 3"],
  ["Part 3", "30", "2", "Model 2,Model 3"]
];

// Salvaged parts data
let salvagePartsData = [
  ["Part 4", "15", "4", "Model 1,Model 3"],
  ["Part 5", "25", "6", "Model 2,Model 3"],
  ["Part 6", "35", "2", "Model 1,Model 2"]
];

function populateDropdowns() {
  var skuDropdown = document.getElementById('sku');
  var modelDropdown = document.getElementById('model');

  // Populate SKU dropdown
  skuData.forEach(function(item) {
    var option = document.createElement('option');
    option.value = item[0];
    option.text = item[1] + " - " + item[2];
    skuDropdown.appendChild(option);
  });

  // Populate Model dropdown
  modelData.forEach(function(item) {
    var option = document.createElement('option');
    option.value = item[2];
    option.text = item[0] + " - " + item[1] + " - " + item[2];
