在Javascript中將對象鍵值對轉換為一系列數組

Question

我是Javascript的新手。 我有一個像這樣的Javascript對象：

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

我需要將它轉換為一系列數組，如下所示：

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

這與將2個元素數組的JavaScript數組轉換為對象鍵值對中討論的內容相反。 JQuery解決方案是可以接受的。

Answer 1

您可以映射項目以實現此目的：

  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小數組的數組，見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試試這個。

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