I need help splitting a string in javascript by space ( ), ignoring space inside quotes expression.

I have this string:

var str = 'Time:Last 7 Days Time:Last 30 Days';

I would expect my string to be split to 2:

['Time:Last 7 Days', 'Time:Last 30 Days']

but my code splits to 4:

['Time:', 'Last 7 Days', 'Time:', 'Last 30 Days']

this is my code:

str.match(/(.*?|[^s]+)(?=s*|s*$)/g);

Thanks!

s = 'Time:Last 7 Days Time:Last 30 Days'

s.match(/(?:[^s]+|[^]*)+/g) 



// -> ['Time:Last 7 Days', 'Time:Last 30 Days']

Explained:

(?:         # non-capturing group

  [^s]+   # anything that's not a space or a double-quote

  |         #   or…

           # opening double-quote

    [^]*   # …followed by zero or more chacacters that are not a double-quote

           # …closing double-quote

)+          # each match is one or more of the things described in the group

Turns out, to fix your original expression, you just need to add a + on the group:

str.match(/(.*?|[^s]+)+(?=s*|s*$)/g)

#                         ^ here.
