如何将上传的csv转换为angularjs中的json对象

var fileInput = document.getElementById('csvFileInput');
var file = fileInput.files[0];
var reader = new FileReader();

reader.onload = function(e) {
  var csv = e.target.result;
  // 在这里进行CSV解析操作
};

reader.readAsText(file);

function csvToJSON(csv) {
  var lines = csv.split('\n');
  var result = [];

  var headers = lines[0].split(',');
  for (var i = 1; i < lines.length; i++) {
    var obj = {};
    var currentLine = lines[i].split(',');

    for (var j = 0; j < headers.length; j++) {
      obj[headers[j]] = currentLine[j];
    }

    result.push(obj);
  }

  return JSON.stringify(result);
}

var json = csvToJSON(csv);

app.controller('MainController', function($scope) {
  $scope.data = JSON.parse(json);
});
