Question

我正在尝试使用PapaParse解析本地CSV文件并遍历JSON，以便仅从文件中输出特定数据。

示例：我只希望“磨粉描述”列与adidas && Champion匹配，所有其他数据都将被丢弃。

如果您需要更多说明，请随时询问，我会定期在这里检查。

papa.parse(file, {
  worker: true,
  header: true,
  transformHeader: true,
  step: function(result) {
    var data = result.data;
    for (var i = 0; i < data.length; i++) {
      var millDescription = JSON.stringify(data[i]["Mill Description"]);
      if (
        millDescription.includes("adidas") ||
        millDescription.includes("Champion")
      ) {
      // This is where I need help
      }
    }
  },
  complete: function(result, csv) {
    console.log("parsing complete read: ", result, csv); // Nothing is passed to here yet.
  }
});

Answer 1

尝试

 papa.parse(file, {
  worker: true,
  header: true,
  transformHeader: true,
  step: function(result) {
    let data = result.data;
    data = data.filter(d => d["Mill Description"].includes('adidas') || d["Mill Description"].includes('adidaChampions'));
  },
  complete: function(result, csv) {
    console.log("parsing complete read: ", result, csv); // Nothing is passed to here yet.
  }
});

输出看起来像这样，有多个JSON数组，然后我的问题是如何解析所有数据以转换回csv文件？
