javascript - 使用对象创建二维数组 - Javascript

Question

我根据查询从 firebase 检索了以下数据。我尝试创建一个二维数组但没有成功。

我该怎么做？

Object {address: "6220 Lawson Dr, Haymarket, VA 20169", name: "Dave", petProfile: "A"}

Object {address: "2121 I St NW, Washington, DC 20052", name: "George W", petProfile: "A"}

预期结果:

[
 ["6220 Lawson Dr, Haymarket, VA 20169", "Dave", "A"],
 ["2121 I St NW, Washington, DC 20052", "George W", "A"]
]

我的代码:

var myArr = [];          
for (var i=0, len=data.length; i<len; i++) {
    for (var j=0, len2=data[i].length; j<len2; j++) {
        var sub = data[i][j]; 
    }
}
 myArr.push(sub);
 console.log(myArr);

您可以将两个对象移动到一个数组中，使用 Object.keys 和 Array#map 遍历每个对象并只返回值。

var obj1 = {address: "6220 Lawson Dr, Haymarket, VA 20169", name: "Dave", petProfile: "A"},
    obj2 = {address: "2121 I St NW, Washington, DC 20052", name: "George W", petProfile: "A"},
    arr = [obj1, obj2],
    res = arr.map(c => Object.keys(c).map(v => c[v]));
    
    console.log(res);
