javascript - 正则表达式匹配双引号内的单引号(单独)？

Question

如何编写正则表达式来匹配它(参见箭头):

"this is a ->'<-test'" // note they are quotes surrounding a word

还有其他匹配的吗？

"this is a 'test->'<-"

在 JavaScript 中？ (然后，比如说，用双引号替换它们？)

我想用两个正则表达式分别匹配它们。

Answer 1

第一种情况

/'\b/

Regex Demo

"this is a 'test' there is another 'test'".replace(/'\b/g, '"'))
=> this is a "test' there is another "test'

第二种情况

/\b'/

Regex Demo

"this is a 'test' there is another 'test'".replace(/\b'/g, '"'))
=> this is a 'test" there is another 'test"
