使用条件填充列表框多列

<select id="myListbox"></select>

var data = [
  { name: 'Apple', category: 'Fruit' },
  { name: 'Carrot', category: 'Vegetable' },
  { name: 'Orange', category: 'Fruit' },
  { name: 'Broccoli', category: 'Vegetable' }
];
var condition = 'Fruit'; // 假设条件为"Fruit"
var filteredData = data.filter(item => item.category === condition);

var listBox = document.getElementById('myListbox');
filteredData.forEach(item => {
  var option = document.createElement('option');
  option.text = item.name;
  listBox.add(option);
});
