Question

我有

的对象

{
0: "United States",
1: "India",
2: "Germany",
3: "Brazil",
4: "Taiwan",
5: "Israel",
6: "United Kingdom"
}

我只想使其像仅使用jQuery或Javascript

["United States", "India", "Germany".....]

我已经尝试了一些代码，例如

.reduce（）、. flat（）或.concat（）

但仍然无法正常工作

Answer 1

您可以将对象分配给数组。这种方法尊重键。

var object = { 0: "United States", 1: "India", 2: "Germany", 3: "Brazil", 4: "Taiwan", 5: "Israel", 6: "United Kingdom" },
    array = Object.assign([], object);

console.log(array);

Answer 2

$.map({0:"united states", 1: "India"}, function(q,w){return(w)})
> ["united states", "India"]

  0: "United States",
1: "India",
2: "Germany",
3: "Brazil",
4: "Taiwan",
5: "Israel",
6: "United Kingdom"
}

var result = Object.values(obj)

console.log(result);

var result = Object.keys(obj).map(function(key) {
  return obj[key];
});

console.log(result);

Answer 4

  const object = {
    0: 'United States',
    1: 'India',
    2: 'Germany',
    3: 'Brazil',
    4: 'Taiwan',
    5: 'Israel',
    6: 'United Kingdom'
  };

  const countries = Object.values(object);

国家/地区将包含您想要的列表

将对象简化为简单数组
