如何按字母顺序排序单个对象？ [英] How to sort single object alphabetically?

问题描述

我想按字母顺序对单个对象进行排序...

I want to sort single object alphabetically...

维护其键和值ex：

输入是： {2：a，3：e，4：h，5：g，6：d，7 ：i，8：c，9：f，10：b}

input is: {2: "a", 3: "e", 4: "h", 5: "g", 6: "d", 7: "i", 8: "c", 9: "f", 10: "b"}

我需要输出： { 2：a，10：b，8：c，6：d，3：e，9：f，5：g，4：h，7： i}

i need output: {2: "a", 10: "b", 8: "c", 6: "d", 3: "e", 9: "f", 5: "g", 4: "h", 7: "i"}

这是我的js代码：

var myObject = {2: "a", 3: "e", 4: "h", 5: "g", 6: "d", 7: "i", 8: "c", 9: "f", 10: "b"}

keysSorted = Object.keys(myObject).sort(function(a,b){return myObject[a]-myObject[b]});
console.log(keysSorted);

推荐答案

如果您只想对属性名称数组进行排序，请使用 String＃localeCompare 用于比较字符串。

If you just want to sort the property name array then use String#localeCompare for comparing string.

var myObject = {
  2: "a",
  3: "e",
  4: "h",
  5: "g",
  6: "d",
  7: "i",
  8: "c",
  9: "f",
  10: "b"
}

keysSorted = Object.keys(myObject).sort(function(a, b) {
  return myObject[a].localeCompare(myObject[b])
});
console.log(keysSorted);
