var text=“Afganistan (+86)”
var code=text.sub(/\w+/, ‘’)
result: code = (+86)

var text = “Antigua and Barbuda (+1268)”
var code=text.sub(/\w+/, ‘’)
result : code = and Barbuda (+1268)"

what regular expression I can try to get second one as first. ie (+1268)

Do you want “(+1268)” from the second query? If so, does

var code=text.sub(/[\w+ ]/, ‘’)

work? See Rubular: [\w+ ] for where I show it works.

Thanks,

“Antigua and Barbuda (+1268)”.scan(/\d+/).to_s
=> 1268

“Antigua and Barbuda (+1268)”.scan(/(+\d+)/).to_s
=> (+1268)

There’s a nice technique for quickly getting a substring from a
string using a subscript-style notation:

“Antigua and Barbuda (+1268)”[/(+\d+)/] # “(+1268)”
