Convert object key-value pairs to a series of arrays in Javascript
提问by Akshat Mahajan
I am new to Javascript. I have a Javascript object like so:
我是 Javascript 的新手。我有一个像这样的 Javascript 对象：
s = {"Toothless":"Dragon","Foo":"Bar"};
I need to convert it into a series of arrays, like so:
我需要将其转换为一系列数组，如下所示：
out = [["Toothless","Dragon"],["Foo","Bar"]];
This is the reverse of what is discussed in Convert JavaScript array of 2 element arrays into object key value pairs. A JQuery solution is acceptable.
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相反。JQuery 解决方案是可以接受的。

You can map over the items to achieve this:
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);回答by Kobi
let s = {"Toothless":"Dragon","Foo":"Bar"};
let out = Object.entries(s);
and you get outas an array of small arrays,
see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries
你会得到out一个小数组的数组，请参阅https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries

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

Try this using jQuery.
使用 jQuery 试试这个。
var tempArr = [];
s = {"Toothless":"Dragon","Foo":"Bar"};
$.each(s,function(i,v){
tempArr.push([i,v]);
});
