javascript - 如何获取 JSON 文件中的特定数据

Question

我试图仅以 JSON 格式获取每个数据中的见解。我使用 lodash 按月过滤它，但我不能只了解每个对象。

let insight5 = [{
    insight: "valid",
    reportMonth: "January - June 2018"
  },
  {
    insight: "invalid",
    reportMonth: "January 2018"
  },
  {
    insight: "valid",
    reportMonth: "February 2018"
  },
  {
    insight: "valid",
    reportMonth: "March 2018"
  },
  {
    insight: "valid",
    reportMonth: "April 2018"
  },
  {
    insight: "valid",
    reportMonth: "May 2018"
  },
  {
    insight: "valid",
    reportMonth: "June 2018"
  },
];


function filterData(data, month) {
  let filtered = _.filter(data, x => x.reportMonth == month)
  return filtered[0];
}

Answer 1

要仅获得洞察力，您需要返回该属性:

return filtered.length > 0 && filtered[0].insight;

我先检查长度，以防找不到匹配的数据。
