（javascript）CSV文件到javascript对象[重复]

Question

我是 JavaScript 菜鸟。 我需要从 csv 文件到 javascript 对象。

<<1.csv>>
apple
banana
car

<<2.csv>>
apple
banana

<<3.csv>>
apple
car
day

<<4.csv>>

<<5.csv>>
car

我想要这样的东西。

x = { "first": ["apple", "banana", "car"],
      "second": ["apple", "banana"],
      "third": ["apple", "car", "day"],
      "fourth": [],
      "fifth": ["car"]
}

我该怎么办？

Answer 1

下面是示例代码。

var x = {};

function readCSV(filename, objectKey) {
    var bufferString; 
    fs.readFile(filename,function (err,data) {
        if (err) {
            return console.log(err);
        }

        //Convert and store csv information into a buffer. 
        bufferString = data.toString();

        //create an array that contains each line as an element
        x[objectKey] = bufferString.split('\n');
    });
}

readCSV('1.csv', 'first');
readCSV('2.csv', 'second');
readCSV('3.csv', 'third');
readCSV('4.csv', 'forth');
readCSV('5.csv', 'fifth');
