替换字符串中的特定字符 - JavaScript [英] Replacing specific characters in a string - JavaScript

问题描述

好的，我正在尝试创建一个 JavaScript 函数来替换字符串中的特定字符.我的意思是，让我们说，一个字符一个字符地搜索一个字母，如果匹配，用另一个字符替换它.例如，将a"替换为x":Hello, how are you? 变成 Hello, how xre you? 和 Greetings and salutations 变成问候和问候.

Okay, so I'm trying to create a JavaScript function to replace specific characters in a string. What I mean by this is, lets say, searching a string character by character for a letter and if it matches, replacing it with another character. Ex, replacing "a" with "x": Hello, how are you? becomes Hello, how xre you? and Greetings and salutations becomes Greetings and sxlutations.

推荐答案

要删除多个字符，您可以使用正则表达式

for removing multiple characters you could use a regex expression

yourString.replace(new RegExp('a', 'g'), 'x')

使用不区分大小写的匹配删除相同的内容

for removing the same with a case-insensitive match use

yourString.replace(new RegExp('a', 'gi'), 'x')
