Question

我是Javascript的新手。我有一个像这样的Javascript对象：

s = {"Toothless":"Dragon","Foo":"Bar"};

我需要将它转换为一系列数组，如下所示：

out = [["Toothless","Dragon"],["Foo","Bar"]];

这与Convert JavaScript array of 2 element arrays into object key value pairs中讨论的相反。 JQuery解决方案是可以接受的。

Answer 1

您可以映射项目以实现此目的：

    s = {"Toothless":"Dragon","Foo":"Bar"};
    var out = Object.keys(s).map(function(data){
        return [data,s[data]];
    });
    console.log(out);

Answer 2

let s = {"Toothless":"Dragon","Foo":"Bar"};

let out = Object.entries(s);

你得到out作为一个小数组的数组，见https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries

Answer 3

var s = {"Toothless":"Dragon","Foo":"Bar"};
var out = [];
for (var key in s){
    out.push([key, s[key]]);
}

Answer 4

使用jQuery试试这个。
