在javascript中读取文件名中包含随机字符串的csv文件

<input type="file" id="csvFileInput" accept=".csv" />

const fileInput = document.getElementById('csvFileInput');
fileInput.addEventListener('change', function(event) {
  const file = event.target.files[0];
  // 进行后续操作
});

const reader = new FileReader();
reader.onload = function(event) {
  const fileContent = event.target.result;
  // 进行后续操作，如解析CSV数据
};
reader.readAsText(file);

function parseCSV(csv) {
  const lines = csv.split('\n');
  const headers = lines[0].split(',');
  const data = [];
  for (let i = 1; i < lines.length; i++) {
    const values = lines[i].split(',');
    if (values.length === headers.length) {
      const row = {};
      for (let j = 0; j < headers.length; j++) {
        row[headers[j]] = values[j];
      }
      data.push(row);
    }
  }
  return data;
}

const csvData = parseCSV(fileContent);
console.log(csvData);
