js正则匹配小括号中的内容

Question

varaa="ldfjsldfj(dsfasjfj3124123)";小括号中是任意内容，怎样匹配出来

Answer 1

varaa="ldfjsldfj(dsfasjfj3124123)";varresult=aa.match(/\(([^)]*)\)/);//此时result＝["(dsfasjfj3124123)","dsfasjfj3124123"];if(result){console.log(result[1]);//"dsfasjfj3124123"}

Answer 2

可以使用如下正则：/\((.+)\)/g测试结果如下：'ldfjsldfj(dsfasjfj3124123)'.match(/\((.+)\)/g);console.log(RegExp.$1);//dsfasjfj3124123
