如何将逗号分隔的字符串转换为数组? [英] How can I convert a comma-separated string to an array?

问题描述

我有一个逗号分隔的字符串，我想将其转换为数组，以便可以循环遍历它.

I have a comma-separated string that I want to convert into an array, so I can loop through it.

有内置的功能吗?

例如，我有这个字符串

var str = "January,February,March,April,May,June,July,August,September,October,November,December";

现在我想用逗号将其分割，然后将其存储在数组中.

Now I want to split this by the comma, and then store it in an array.

推荐答案

var array = string.split(',');

MDN参考，主要是对于limit参数的可能意外行为很有帮助. (提示:"a,b,c".split(",", 2)出现在["a", "b"]上，而不是["a", "b,c"].)

MDN reference, mostly helpful for the possibly unexpected behavior of the limit parameter. (Hint: "a,b,c".split(",", 2) comes out to ["a", "b"], not ["a", "b,c"].)
