在Javascript中将整数转换为其等效字符 [英] Convert integer into its character equivalent in Javascript
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。我可以构建一个数组,只在我需要的时候查看它,但我想知道是否有内置函数为我做这个?我通过Google找到的所有示例都使用ASCII值,而不是字母表中的字符位置。
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 characters position in the alphabet.
干杯。 :)
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是小写的ASCII码'一个'。如果你想要大写字母,用97替换97(大写'A')。请注意,如果 n> 25
,你将超出字母范围。
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.
