在JavaScript中将数组对象转换为数组数组

Question

I have an object with arrays, each of which has numbers with double quotes, and I'd like to convert it into an array of arrays without double quotes.

This

> Object { CategoryA: Array[182], CategoryB: Array[180],
> CategoryC: Array[182], CategoryD: Array[171],
> CategoryE: Array[182], CategoryF: Array[183] }

to

Array [ Array[182], Array[182], Array[182], Array[182], Array[182], Array[182] ]

I tried .replace(/"/g, ""); but I'm getting that replace is not a function.

JSON.stringify and JSON.parse didn't help me and a for loop

for (var i = 0; i < data.length; i++) {
    data2[i] = data[i].replace(/"/g, "");
}
console.log(data2);

returns double quotes.

UPDATE

This is how my json looks like

{"CategoryA": ["297,239", "277,227", "279,310", "297,766"],
 "CategoryB": ["15,479,207", "14,845,266", "15,454,549"],
 "CategoryC": ["285,648", "295,982", "300,306", "302,508"]
} 

Answer 1

You can use map in combination with Object.keys like this:

var result = Object.keys(yourObject).sort().map(function(key) {
    return yourObject[key].map(function(num) {
        return +num.replace(/,/g, '');
    });
});

Please note that the comma , in your numbers it's for formatting, not a floating point.

 var yourObject = {"CategoryA": ["297,239", "277,227", "279,310", "297,766"], "CategoryB": ["15,479,207", "14,845,266", "15,454,549"], "CategoryC": ["285,648", "295,982", "300,306", "302,508"] } ; var result = Object.keys(yourObject).sort().map(function(key) { return yourObject[key].map(function(num) { return +num.replace(/,/g, ''); }); }); console.log(result); 

Thank you @Rayon.

You could sort the keys (to maintain alphabetical order) and apply a replace for changing the comma to point and a casting to number.

 var object = { "CategoryA": ["297,239", "277,227", "279,310", "297,766"], "CategoryB": ["15,479,207", "14,845,266", "15,454,549"], "CategoryC": ["285,648", "295,982", "300,306", "302,508"] }, array= Object.keys(object).sort().map(function(k) { return object[k].map(function (a) { return +a.replace(/,/g, ''); }); }); console.log(array);
