Question

如果角色出现在两个特定的角色之间，我该如何替换？即使之前和之后都有文字吗？

例如，如果我有这样的字符串：

var text = "For text `in between two backticks, replace all #es with *s`. It should `find all such possible matches for #, including multiple ### together`, but shouldn't affect ### outside backticks."

我想要的输出是：

"For text `in between two backticks, replace all *es with *s`. It should `find all such possible matches for *, including multiple *** together`, but shouldn't affect ### outside backticks."

我已获得以下代码：

text = text.replace(/`(.*?)#(.*?)`/gm, "`$1*$2`");

使用一个匹配反引号的简单/`[^`]+`/g正则表达式，然后使用除反引号之外的1个字符，然后再使用反引号，并替换回调中的#：

＆＃13;

var text = "For text `in between two backticks, replace all #es with *s`. It should `find all such possible matches for #, including multiple ### together`, but shouldn't affect ### outside backticks.";
var res = text.replace(/`[^`]+`/g, function(m) {
  return m.replace(/#/g, '*');
});
console.log(res);

＆＃13;

替换两个其他字符之间的多个相同字符的出现
