Javascript 正则表达式帮助

Question

我承认，这么多年过去了，我对正则表达式的理解很烂。我希望有人能尽快帮助我。

var str = "11 FT 0 IN | 10' ( +$2,667.00 )";
var match = str.match(/**no clue what to do**/g);

// results needed
match[0] = "11 FT 0 IN";
match[1] = "10'";
match[2] = "( +$2,667.00 )";

Answer 1

 /^\s*((?:\s*[^\s|])+)\s*\|\s*((?:\s*[^\s(])+)\s*(.+)$/

结果在 matches[1] 到 [3] 中。 [0] 始终是整个匹配项。

 ((?:\s*[^\s|])+)  # non-pipe-or-space characters,

 \s*               # more optional spaces

 \s*               # more or more optional spaces
 (.+)              # just chomp everything beyond (the "( +$2,667.00 )")
 $                 # end of string
