Question

我需要将此CSV数据转换为javascript数组：

5/27/2019 19:54:09,5/27/2019, GSCOH6EUYN77D5N5HB22222222,"defgv",street
5/27/2019 20:21:58,5/27/2019, ZJ2ZOMAFNGTWEITTD333333333,"defgv",apartment
5/27/2019 20:33:09,5/27/2019, E3V5MNRGDU4WV4QVD444444444,"defgv",address
5/27/2019 20:34:39,5/27/2019, NQ5TZYVDIDBCEXBYC555555555,"defgv",home

我尝试使用：

var dataArr = xmlData.split("\n");
var data = dataArr.splice(1,dataArr.length-1);

但是它不起作用。.由于字符defgv中的空格，请考虑一下它。请您帮我转换一下。

预期输出：-

["5/27/2019 9:54:09,5/27/2019,GSCOH6EUYN77D5N5HB22222222,defgv,street",
"5/27/2019 20:21:58,5/27/2019,OMAFNGTWEITTD333333333,defgv,apartment"]

相反，m收到的输出为：

0: "5/22/2019 17:10:08,5/22/2019, GSCOH6EUYN77D5N5HB22222222,""
1: "      defgv",street
"
2: "5/22/2019 17:24:19,5/22/2019, OMAFNGTWEITTD333333333,""
3: "      defgv",apartment
"

Answer 1

我不清楚您的输入格式是什么。但是，请猜测一下，您可能必须拆分成字符串，然后将成对的字符串组合成单个字符串。这样可以做到：

const splitIntoJointRows = (data) =>   data .split ('\n')
       .reduce ((a, s, i, ss) => i % 2 ? [...a, ss[i - 1] + s] : a, [])

//-------------------------------------------------------------------------

const data = `5/27/2019 19:54:09,5/27/2019, GSCOH6EUYN77D5N5HB22222222,
     "defgv",street
5/27/2019 20:21:58,5/27/2019, ZJ2ZOMAFNGTWEITTD333333333,
     "defgv",apartment
5/27/2019 20:33:09,5/27/2019, E3V5MNRGDU4WV4QVD444444444,
     "defgv",address
5/27/2019 20:34:39,5/27/2019, NQ5TZYVDIDBCEXBYC555555555,
     "defgv",home
`;

console .log (
  splitIntoJointRows(data)
)

console .log (
  splitIntoJointRows(data)
    .map(s => s.split(/,\s*/))
)

console .log (
  splitIntoJointRows(data)
    .map(s => s.split(/,\s*/))
    .map(([date, a, b, c, d]) => ({date, a, b, c, d}))
)

在该代码段中，还有一个调用，使用该调用可以构建一个由字段数组组成的数组，并且可以将其进一步转换为对象数组（具有已发明键）。
