如何在字符串中的每个字符之间添加空格？ [英] How to add spaces between every character in a string?

问题描述

我正在尝试创建一个在字符串参数的字符之间插入空格的函数，然后返回一个新的字符串，其中包含与参数相同的字符，用空格字符分隔。

I am trying to create a function that inserts spaces between the characters of a string argument then return a new string which contains the same characters as the argument, separated by space characters.

例如

Hello

变为

H e l l o

我是一个大规模的新手，我确信这对某些人来说似乎没有脑子，但我似乎无法得到围绕着它。

I'm a massive novice and I'm sure that this might seem like a no-brain'er to some people, but I just can't seem to get my head around it.

推荐答案

你可以使用 split（） 函数将字符串转换为单个字符数组，并且然后 join（） 函数将其转换回指定连接的字符串g字符（指定空格作为连接字符）：

You can use the split() function to turn the string into an array of single characters, and then the join() function to turn that back into a string where you specify a joining character (specifying space as the joining character):

function insertSpaces(aString) {
  return aString.split("").join(" ");
}

（注意参数 split（）是你要分割的字符，例如，你可以使用 split（，）来分解以逗号分隔的列表，但是如果你传递一个空字符串，它只会拆分每个字符。）

(Note that the parameter to split() is the character you want to split on so, e.g., you can use split(",") to break up a comma-separated list, but if you pass an empty string it just splits up every character.)
