请教JavaScript正则表达式

Question

请问如何用JavaScript的正则表达式提取如下格式的数据/* 任意字符
   任意行数
   任意字符 */
typedef 就是c的多行注释格式后面跟一个typedef关键字是在一堆杂乱的代码中提取我写的要么死循环，要么提取过头了，有高人赐教吗

Answer 1

从代码中提取/* safasfklsdfjlasdfjl */ typedef 为止嘛

Answer 2

JavaScript的正则表达式好像没有单行模式

Answer 3

var r = 'sadfjaskldfjweofjsladkfjlkxjfowiajflfjlaskdjflakjfoawejflasdjl\
sadlfjlasdkjflaskdjflksajdflajsdflj\
asdlkfjlaskdfjlwjlfd\
asldfjlasdfkj\
/*sdflksjdf\
sdlfjlk\
sdfjlskadfj */\
typedefasdlfjasldfjasdf\
asldfjlasdfjlasdf\
asdflkjasdlf';
alert(r.match(/\/\*[\s\S]*?\*\/\s+typedef/g));

Answer 4

[\s\S]*? 这也行呵呵，多谢哈不过这会把一些多余的代码也匹配进来的，如/* kdjfkf
d9f79d *//* 我想要的
    xxxx
    我想要的 */
typedef会把这串全部捕获了，但是我只想捕获下面一部分

Answer 5

var r = '/*sdflksjdf\
sdlfjlk\
sdfjlskadfj */\
sadfjaskldfjweofjsladkfjlkxjfowiajflfjlaskdjflakjfoawejflasdjl\
sadlfjlasdkjflaskdjflksajdflajsdflj\
asdlkfjlaskdfjlwjlfd\
asldfjlasdfkj\
/*sdflksjdf\
sdlfjlk\
sdfjlskadfj */\
typedefasdlfjasldfjasdf\
asldfjlasdfjlasdf\
asdflkjasdlf';
alert(r.match(/\/\*(?:[^*]|\*(?!\/))*\*\/\s+typedef/g));
