javascript - 将JavaScript数组转换为逗号分隔列表的简便方法？(Easy way to turn JavaScript array into comma-separated list?)

Question

I have a one-dimensional array of strings in JavaScript that I'd like to turn into a comma-separated list.(我在JavaScript中有一个一维的字符串数组，我想把它变成以逗号分隔的列表。)

Is there a simple way in garden-variety JavaScript (or jQuery) to turn that into a comma-separated list?(在花园种类的JavaScript（或jQuery）中有一种简单的方法可以将其转换为以逗号分隔的列表吗？) (I know how to iterate through the array and build the string myself by concatenation if that's the only way.)(（我知道如何迭代数组并通过连接自己构建字符串，如果这是唯一的方法。）)   ask by Herb Caudill translate from so
