在Javascript中将对象键值对转换为一系列数组

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"]];

这与将2个元素数组的JavaScript数组转换为对象键值对中讨论的内容相反。 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。

 var tempArr = []; s = {"Toothless":"Dragon","Foo":"Bar"}; $.each(s,function(i,v){ tempArr.push([i,v]); });
