<select id="barcodeScanner"></select>

$(document).ready(function() {
  $('#barcodeScanner').select2({
    ajax: {
      url: 'api/barcode-scanners', // 替换为实际的API地址
      dataType: 'json',
      delay: 250,
      processResults: function(data) {
        return {
          results: data
        };
      },
      cache: true
    },
    placeholder: '选择条形码扫描仪',
    minimumInputLength: 1
  });
});

$('#barcodeScanner').on('select2:select', function(e) {
  var selectedScanner = e.params.data;
  // 处理选择的条形码扫描仪
  console.log(selectedScanner);
});
