JavaScript 正则表达式删除完美匹配的任何前缀

Question

如何删除字符串中的“Dr”、“Dr.”或“dr”？

"Dr. Drake Cohen" would become "Drake Cohen"
"Dr Drake Cohen" would become "Drake Cohen"
"Drake Cohen" would become "Drake Cohen"
"Rachel Smith" would become "Rachel Smith"
"Dr. Rachel Smith" would become "Rachel Smith"

我尝试过的:

str.replace(/dr./i, "")

但这会删除所有 Dr 实例

Answer 1

使用这个正则表达式。

正则表达式: dr[\.\s] 不区分大小写应该打开。

从 revo 的评论来看，避免在 Alexandr 等名称中匹配 dr 要好得多。

正则表达式: \bdr[.\s]\s? 这将在 dr 之前检查 word boundary >.
