如何按对象的值按字母顺序而不是键排序？这是一个对象
{
1: "Arabic"
2: "Bulgarian"
3: "Catalan"
4: "Chinese"
5: "Croatian"
6: "Czech"
7: "Danish"
8: "Dutch"
9: "English"
10: "Estonian"
11: "Finnish"

13: "German"
14: "Greek"
15: "Hebrew"
16: "Hungarian"
17: "Icelandic"
18: "Indonesian"
19: "Italian"
20: "Japanese"
21: "Korean"

30: "Slovak"
31: "Slovenian"
32: "Spanish"
33: "Swedish"

}，并按字母顺序显示所需输出。

欢迎来到stackOverflow，这个问题将会出现在Javascript section上。
const obj = {1: "Arabic", ... }对于你的问题，如果你需要一个排序的数组：
const sorted = Object.values(obj).sort();如果你需要一个带排序数组的对象：
const newObj = {}
sorted.forEach((name, index) => newObj[index] = name)Stack Overflow用户

实际上，它是一个对象，而不是给定输入的数组。我们不能对对象进行排序，但我们可以通过覆盖Iterator接口来确定对象的迭代顺序，如下所示：
const myObj = {
1: "Arabic",
2: "Bulgarian",
3: "Catalan",
4: "Chinese",
5: "Croatian",
6: "Czech",
7: "Danish",
8: "Dutch",
9: "English",
10: "Estonian",
11: "Finnish",
12: "French",
13: "German",
14: "Greek",
15: "Hebrew",
16: "Hungarian",
17: "Icelandic",
18: "Indonesian",
19: "Italian",
20: "Japanese",
21: "Korean",
22: "Latvian",
23: "Lithuanian",
24: "Norwegian",
25: "Polish",
26: "Portuguese",
27: "Romanian",
28: "Russian",
29: "Serbian",
30: "Slovak",
31: "Slovenian",
32: "Spanish",
33: "Swedish",
34: "Turkish",
35: "Afrikaans",
};
myObj[Symbol.iterator] = function* () {
const entries = Object.entries(this).sort((a, b) => a[1].localeCompare(b[1]));
for (const [key, value] of entries) {
// you could determine what structure looks like here
yield { [key]: value };
}
};
for (const x of myObj) {
console.log(x);
}
