将整数转换为其等效字符，其中 0 =>a, 1 =>乙等

问题描述

我想根据字母表将整数转换为其等效字符.例如:

I want to convert an integer into its character equivalent based on the alphabet. For example:

0 => a
1 => b
2 => c
3 => d

等等.我可以构建一个数组并在需要时查找它，但我想知道是否有内置函数可以为我执行此操作.我通过 Google 找到的所有示例都使用 ASCII 值，而不是字符在字母表中的位置.

etc. I could build an array and just look it up when I need it but I’m wondering if there’s a built in function to do this for me. All the examples I’ve found via Google are working with ASCII values and not a character’s position in the alphabet.

推荐答案

假设你想要小写字母:

var chr = String.fromCharCode(97 + n); // where n is 0, 1, 2 ...

97 是小写a"的 ASCII 码.如果需要大写字母，请将 97 替换为 65(大写A").请注意，如果 n >25，你会跳出字母范围.

97 is the ASCII code for lower case 'a'. If you want uppercase letters, replace 97 with 65 (uppercase 'A'). Note that if n > 25, you will get out of the range of letters.
