根据唯一的key/name过滤数据的状态数组并推送到新的数组

function filterAndPushByKey(dataArray, key) {
  var filteredArray = [];

  for (var i = 0; i < dataArray.length; i++) {
    var data = dataArray[i];

    // 检查key属性是否已经存在于filteredArray中
    var existingData = filteredArray.find(function(filteredData) {
      return filteredData[key] === data[key];
    });

    if (existingData) {
      // 如果已存在，则更新该数据对象的状态
      existingData.status.push(data.status);
    } else {
      // 如果不存在，则创建新的key和对应状态数组，并添加到filteredArray中
      var newData = {};
      newData[key] = data[key];
      newData.status = [data.status];
      filteredArray.push(newData);
    }
  }

  return filteredArray;
}

// 示例数据数组
var dataArray = [
  { name: "A", status: "active" },
  { name: "B", status: "inactive" },
  { name: "A", status: "inactive" },
  { name: "C", status: "active" },
  { name: "B", status: "active" }
];

// 根据唯一的name过滤数据的状态数组并推送到新的数组
var filteredArray = filterAndPushByKey(dataArray, "name");

console.log(filteredArray);
