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

问题描述

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。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？ （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。）

I have a one-dimensional array of strings in JavaScript that I'd like to turn into a comma-separated list. Is there a simple way in garden-variety JavaScript (or jQuery) to turn that into a comma-separated list? (I know how to iterate through the array and build the string myself by concatenation if that's the only way.)

推荐答案

< a href =https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/join =noreferrer> Array.prototype.join（）方法：

var arr = ["Zero", "One", "Two"];

document.write(arr.join(", "));
