从mongodb中的文档开头删除“

Question

I have a mongodb collection like this:

name: 'john'
family: '"smith"'

i want to remove " from first and end of family, for example convert '"smith"' to 'smith' . i know should use update and regular expression like this /^"/, but how?

Thanks for any reply.

Answer 1

Javascript example:

> '"smith"'.replace(/^"|"$/g, '')
'smith'

/^"|"$/g matches leading quote ( ^" ) or ( | ) or trailing quote ( "$ ).
