用特殊字符替换子字符串

Question

我有一个字符串，其中包含一些包含在一些特殊字符中的子字符串。 这是我的代码：

var p = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?';

var regex = /[\\[dog\\]]/g;

console.log(p.replace(regex, 'ferret'));

代码给了我输出The quick brown fox jumps over the lazy ferretdogferret. If the ferretdogferret reacted, was it really lazy? The quick brown fox jumps over the lazy ferretdogferret. If the ferretdogferret reacted, was it really lazy? 但我期待The quick brown fox jumps over the lazy ferret. If the ferret reacted, was it really lazy? The quick brown fox jumps over the lazy ferret. If the ferret reacted, was it really lazy?

Answer 1

只需删除整个模式周围的字符集，然后匹配\\[dog\\] ：

 var p = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?'; var regex = /\\[dog\\]/g; console.log(p.replace(regex, 'ferret')); 

Answer 2

您可以使用标准JS并像下面那样处理它。

 let txt = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?' let txt1 = txt.split(' ') txt1.map((word, i) => word.includes('dog') ? txt1[i]='ferret':null ) let sentence = txt1.join(' ') console.log(sentence)
