javascript - 删除括号内的单词

Question

嗨，我是 javascript 的新手，所以我想知道如何删除括号内的单词并删除括号？我还想删除冒号之前的单词，然后用逗号替换括号，最后一个单词除外。例如，如果字符串包含：

language:chinese (29)parody:hyouka (73)character:fuyumi irisu (12)houtarou oreki (12)group:shuudan bouryoku (41)artist:murasaki syu (49)misc:schoolgirl (11)nakadashi (11)acting like a pet (6)

那么输出将变为

chinese,hyouka,fuyumi irisu,houtarou oreki,shuudan bouryoku,murasaki syu,schoolgirl,nakadashi,acting like a pet

我怎么能用javascript做到这一点？这是代码，它不起作用

var str = "language:chinese (29)parody:hyouka (73)character:fuyumi irisu (12)houtarou oreki (12)group:shuudan bouryoku (41)artist:murasaki syu (49)misc:schoolgirl (11)nakadashi (11)acting like a pet (6)";

var tags = str.replace(/\s*\(.*?\)\s*/g, ','));
final = tags.replace(/.*(?=:)/i, "");
alert(final);

Answer 1

使用 [^)]+ 表示此处打开后没有右括号：

var str = "language:chinese (29)parody:hyouka (73)character:fuyumi irisu (12)houtarou oreki (12)group:shuudan bouryoku (41)artist:murasaki syu (49)misc:schoolgirl (11)nakadashi (11)acting like a pet (6)";  

var tags = str.replace(/\s?\([^\)]+\)/g, ',')
              .replace(/[^:]+:([^,]+),/g,'$1,')
              .replace(/,$/,'');
alert(tags);​

甚至很简单：

var tags = str.replace(/([^:]+:)?([^(]+)\s\([^\)]+\)/g,'$2,')
              .replace(/,$/,'');
