Set.prototype.values()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

values() 方法回傳一個 Iterator 物件,包含著 Set 物件中所有元素,由插入順序排序。

keys() 是這個方法的替身(為了與 Map 物件保持相似性);他運行的完全一模一樣,回傳 Set 中元素的 values

嘗試一下

const set1 = new Set();
set1.add(42);
set1.add("forty two");

const iterator1 = set1.values();

console.log(iterator1.next().value);
// Expected output: 42

console.log(iterator1.next().value);
// Expected output: "forty two"

語法

js
mySet.values();

範例

使用 values()

js
var mySet = new Set();
mySet.add("foo");
mySet.add("bar");
mySet.add("baz");

var setIter = mySet.values();

console.log(setIter.next().value); // "foo"
console.log(setIter.next().value); // "bar"
console.log(setIter.next().value); // "baz"
