用Javascript中设置的字典数组替换字符串中的字母 [英] Replace letters in string with a dictionary array set in Javascript

问题描述

我有一个名为

"Pizza2Day!"

我要使用数组集替换的

.在这个数组集中，我将原始字母作为参考

that I want to replace using a array set. In this array set I have the original alphabets as reference

var originalValues = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'];

然后我设置了加密密钥

var encryptedValues = ['m', 'h', 't', 'f', 'g', 'k', 'b', 'p', 'j', 'w', 'e', 'r', 'q', 's', 'l', 'n', 'i', 'u', 'o', 'x', 'z', 'y', 'v', 'd', 'c', 'a'];

我想做的是在普通字符串(a，b，c，d)的原始字符串"Pizza2Day"中找到所有出现的内容，并将它们替换为加密集中(m，n，h，f)中的替换项.因此结果将是"Njaam2Fmc！"

what I want to do is find any occurrences in the original string "Pizza2Day" of normal alphabets (a,b,c,d) and replace them with their substitutes in the encryption set (m,n,h,f). So the result would be "Njaam2Fmc!"

我将如何去做?在这种情况下，循环会派上用场吗?

How would I go about doing this? Will a loop come in handy in this case?

推荐答案

另一种方法.

var dictionary = { "a": "m", "b": "h", "c": "t", "d": "f", "e": "g", "f": "k", "g": "b", "h": "p", "i": "j", "j": "w", "k": "e", "l": "r", "m": "q", "n": "s", "o": "l", "p": "n", "q": "i", "r": "u", "s": "o", "t": "x", "u": "z", "v": "y", "w": "v", "x": "d", "y": "c", "z": "a", "A": "M", "B": "H", "C": "T", "D": "F", "E": "G", "F": "K", "G": "B", "H": "P", "I": "J", "J": "W", "K": "E", "L": "R", "M": "Q", "N": "S", "O": "L", "P": "N", "Q": "I", "R": "U", "S": "O", "T": "X", "U": "Z", "V": "Y", "W": "V", "X": "D", "Y": "C", "Z": "A" },
    string = "Pizza2Day!",
    result = string.replace(/[a-z]/gi, m => dictionary[m]);
    
    console.log(result);
