如何在Chrome中将设置转换为数组？ [英] How to convert a Set to an Array in Chrome?

问题描述

如何将设置转换为数组？给出了转换设置为阵列，其中没有一个当前在Chrome浏览器中可用。

How to convert Set to Array? gives three answers for converting a Set to an Array, none of which currently work in the Chrome browser.

假设我有一个简单的Set

Let's say I have a simple Set

var set_var = new Set(['a', 'b', 'c']);

我可以迭代我的变量并将元素添加到空数组中

I can iterate through my variable and add the elements to an empty array

var array_var = [];
set_var.forEach(function(element){array_var.push(element)});

但是，有没有其他方法可以做到这一点，并提供更广泛的浏览器支持？

But are there any other ways to do this that have wider browser support?

推荐答案

为什么不尝试使用set iterator？

Why not give a try with set iterator?

function setToArray(set) {
  var it = set.values(),
      ar = [],
      ele = it.next();

  while(!ele.done) {
    ar.push(ele.value);
    ele = it.next();
  }

  return ar;
}

setToArray(new Set(['a', 'b', false, 0, 'c'])); // ["a", "b", false, 0, "c"]
