javascript - JS 正则表达式匹配单词，包括空格包围的单词

Question

表达式:

/(^|[^ \/?$])\b(foo)\b/g

测试字符串:

foo             - need this 1
<div>foo</div>  - need this 2
 foo            - need this 3

Foo             - dont need this
foobar          - dont need this
/foo/           - dont need this

替换:

$1bar

需要帮助来改进此正则表达式以与 ex# 3 一起使用。See demo

Answer 1

尝试 (^|[^\/])\b(foo)\b 并将替换更改为 $2bar
