Javascript 正则表达式 - 括号引用

Question

I'd like to somehow replace the string sequence "*" with (*) using a regex in Javascript. Replacing things between quotes to be between opening and closing parenthesis.

For example "apple" to (apple)

Any ideas?

Answer 1

Try something like:

str.replace(/"(.*?)"/g, function(_, match) { return "(" + match + ")"; })

Or more simply

str.replace(/"(.*?)"/g, "($1)")

Note the "non-greedy" specifier ? . Without this, the regexp will eat up everything including double quotes up until the last one in the input. See documentation here . The $1 in the second fragment is a back-reference referring the first parenthesized group. See documentation here .

Answer 2

You could try something like

replace(/"(.*?)"/g, "($1)")

Example

"this will be \"replaced\"".replace(/"(.*)"/, "($1)")
=> this will be (replaced)

"this \"this\" will be \"replaced\"".replace(/"(.*?)"/g, "($1)")
=> this (this) will be (replaced)
