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"

我所尝试的：

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

但这将删除所有Dr实例，并使用此正则表达式

Regex:

dr[\.\s]

不区分大小写应处于启用状态

从revo的评论来看，这一点更好，避免在

Alexandr

等名称中匹配

dr

Regex:

\bdr[.\s]\s？

这将在

dr

之前检查

单词边界
几乎没有改进-dr[\.\s]\s？
@Kinduser:dr后面是否有可选空格？@Kinduserdr[\.\s]\s*
更好。@ibrahimmahrir是的，*
更好。甚至dr[.\s]+
@ibrahimmahrir.replace（/^[dr\.]+/gi'）
