javascript - 如何将逗号分隔的字符串转换为数组？(How to convert a comma separated string to an array?)

Question

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

(我有一个逗号分隔的字符串，我想将其转换成数组，因此可以循环遍历它。)

Is there anything built-in to do this?

(有内置的功能吗？)

For eg I have this string

(例如，我有这个字符串)

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

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

(现在我想用逗号将其分割，然后将其存储在数组中。)

Answer 1

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

MDN reference , mostly helpful for the possibly unexpected behavior of the limit parameter.

(MDN参考 ，主要对limit参数可能发生的异常行为很有帮助。)

(Hint: "a,b,c".split(",", 2) comes out to ["a", "b"] , not ["a", "b,c"] .)

(（提示： "a,b,c".split(",", 2)出现在["a", "b"] ，而不是["a", "b,c"] 。）)
