Gunakan menu lungsur untuk menukar perkara yang muncul dalam jadual

Question

Saya cuba mencipta borang pembaikan mudah menggunakan HTML, menggunakan dropdown saya mahu dapat memilih model dan kemudian memaparkan semua bahagian yang serasi dalam dua jadual, satu untuk bahagian baharu dan satu untuk sekerap. Pada masa ini saya sedang mengodkan data ke dalam JavaScript semasa menjalankan demo saya. Masalah yang saya hadapi ialah senarai bahagian tidak menunjukkan apa-apa kecuali tajuk. Apa yang saya terlepas? RepairFo

Anda akan 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]Ia mewakili model. Saya cadangkan anda menambah pilihan kosong di bahagian atas seperti "Pilih Model" supaya tiada pilihan dipilih secara lalai apabila halaman dimuatkan. Jangan gunakan

。请停止使用 var，使用 const 或 let di luar perenggan. Jika data akan ditukar, gunakan let, untuk data tetap, gunakan 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"]
