如何将Papa.parse结果放入数组 [英] How to get Papa.parse results into an array

问题描述

预警，我是js的新手，我制作的以下代码摘自 从Javascript对象中的CSV检索解析数据(使用爸爸解析)

Forewarning, I am new to js and I crafted the code below was taken from Retrieve parsed data from CSV in Javascript object (using Papa Parse)

我的目标=将一个csv文件解析为一个数组，并在其他一些操作中使用该数组.我可以看到文件已通过"console.log("Row:"，row.data);正确解析，但是我无法弄清楚如何将整个数组/数据集转换为单独的变量，更不用说将其转换为单独的变量了"doSAtuff"功能.

my goal = parse a csv file into an array, and use that array in a few other operations. I can see that the file is getting parsed properly via the "console.log("Row:", row.data);", but I cannot figure out how to get that entire array/dataset into a separate variable, much less into the "doSAtuff" function.

function parseData(url, callBack) {
  Papa.parse(url, {
        download: true,
        header: true,
        dynamicTyping: true,
        comments: "*=",
        step: function(row) {
            console.log("Row:", row.data);
        },
        complete: function(results) {
          callBack(results.data);
        }
    });
}

function doStuff(data) {
    //Data should be usable here, but is emtp
    console.log("doStuff - console log '" + data + "' ?");
}

parseData(inputFile, doStuff);

我思考我想做类似的事情...

I think I want to do something like...

var csvArray = [];

csvArray = Papa.parse(url, {
        download: true,
        header: true,
        dynamicTyping: true,
        comments: "*
...

<some other stuff with csvArray>

但是现在我有点被车轴缠住了.

but i'm a bit wrapped around the axle at the moment.

推荐答案

我知道，如果删除header: true设置，则Papa.parse将返回一个数组而不是对象.

I know that if you remove the header: true setting then Papa.parse will return you an Array instead of an Object.

或者，您可以仅使用以下方法将返回的对象转换为数组:

Alternatively you could just convert the object that is returning into an array using something like:

function _arrayify(obj) { return Object.keys(obj).map(function (k) { return obj[k]; }) }
