将具有多个数组的对象转换为多维数组

Question

I have this format:

Data = {
    "count": [ 62, 58, 10, 6 ],
    "categoires": [ "a1", "a2", "a3", "a4" ]
}

I need to get get data in to the following format:

data = [
    [ "a1", 62 ],
    [ "a2", 58 ],
    [ "a3", 10 ],
    [ "a4", 6 ]
]

Can anyone help me do this?

Answer 1

You can loop using for and length properties:

var data = [];
for (var i = 0; i < Data.count.length; i++)
    data[i] = [ Data.categoires[i], Data.count[i] ];

Answer 2

Try using while loop

 var data = { "count": [62, 58, 10, 6], "categoires": ["a1", "a2", "a3", "a4"] } var res = [], // array to push values to i = 0, // begin at index `0` len = data["categoires"].length; // max length while (i < len) { res.push([data["categoires"][i], data["count"][i]]); // push data tob `res` ++i; // increment index } console.log(res); document.body.textContent = JSON.stringify(res, null, 2)

 body { white-space:pre; }
