如何在JavaScript中将映射键值转换为数组

Question

我有一个Map，其中包含键和它们的值。我希望将所有键值转换为数组。

const gameEvents = new Map([
  [17, '⚽ GOAL'],
  [36, ' Substitution'],
  [47, '⚽ GOAL'],
  [61, ' Substitution'],
  [64, ' Yellow card'],
  [69, ' Red card'],
  [70, ' Substitution'],
  [72, ' Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, ' Yellow card'],
]);

我希望我的新数组看起来像这样

['⚽ GOAL',' Substitution','⚽ GOAL' ,' Substitution', ' Yellow card', ' Red card', ' Substitution',' Substitution',, '⚽ GOAL', '⚽ GOAL', ' Yellow card']

Answer 1

这就行了

​

const gameEvents = new Map([
  [17, '⚽ GOAL'],
  [36, ' Substitution'],
  [47, '⚽ GOAL'],
  [61, ' Substitution'],
  [64, ' Yellow card'],
  [69, ' Red card'],
  [70, ' Substitution'],
  [72, ' Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, ' Yellow card'],
]);

console.log([...gameEvents.values()]);

​

Answer 2

试试这个：

​

const gameEvents = [
  [17, '⚽ GOAL'],
  [36, ' Substitution'],
  [47, '⚽ GOAL'],
  [61, ' Substitution'],
  [64, ' Yellow card'],
  [69, ' Red card'],
  [70, ' Substitution'],
  [72, ' Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, ' Yellow card'],
];

console.log(gameEvents.map(x => x[1]))
