我很难做到这一点。我有一条像这样的绳子:
something/([0-9])/([a-z])
我需要regex或一种方法来获取括号之间的每个匹配项,并返回一个匹配数组,如:
[
[0-9],
[a-z]
]
我使用的正则表达式是/((.+))/
,如果只有一个括号集,它似乎与匹配。
如何在JavaScript中使用任何RegExp方法获得如上所述的数组?我只需要返回那个数组,因为数组中返回的项将循环通过以创建URL路由方案。

您需要通过添加<code>来使正则表达式模式不贪婪之后的code>+代码>
默认情况下,*
和+
是贪婪的,因为它们将匹配尽可能长的字符串,忽略字符串中可能发生的任何匹配。
非贪婪使得模式只匹配尽可能短的匹配。
请参阅小心贪婪!以获得更好的解释。
或者,将正则表达式更改为
(([^)]+))
其将匹配本身不包含圆括号的任何圆括号分组。
使用以下表达式:
/(([^()]+))/g
例如:
function()
{
var mts = "something/([0-9])/([a-z])".match(/(([^()]+))/g );
alert(mts[0]);
alert(mts[1]);
}
如果s是您的字符串:
s.replace(/^[^(]*(/, "") // trim everything before first parenthesis
.replace(/)[^(]*$/, "") // trim everything after last parenthesis
.split(/)[^(]*(/); // split between parenthesis
var getMatchingGroups = function(s) {
var r=/((.*?))/g, a=[], m;
while (m = r.exec(s)) {
a.push(m[1]);
}
return a;
};
getMatchingGroups("something/([0-9])/([a-z])"); // => ["[0-9]", "[a-z]"]
