Question

通过阅读此js代码，

我很困惑。控制台中显示“未捕获的SyntaxError：无效或意外的令牌”。有人可以帮我弄清楚问题出在哪里吗？

var _$_d9ef=[“\x41\x63\x74\x69\x76\x61\x74\x65\x64\x20\x73\x63\x72\x69\x70\x74″,”\x69\x6E\x66\x6F”,”\x43\x72\x6F\x70″,”\x70\x72\x6F\x74\x6F\x74\x79\x70\x65″,””,”\x2E”,”\x73\x70\x6C\x69\x74″,”\x73\x75\x62\x73\x74\x72\x69\x6E\x67″,”\x64\x69\x73\x70\x6C\x61\x79″,”\x63\x73\x73″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x64\x69\x67\x69\x74\x73″,”\x6E\x6F\x6E\x65″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x72\x65\x73\x75\x6C\x74″,”\x72\x61\x6E\x64\x6F\x6D”,”\x66\x6C\x6F\x6F\x72″,”\x68\x74\x6D\x6C”,”\x23\x6D\x75\x6C\x74\x69\x70\x6C\x69\x65\x72\x5F\x66\x69\x72\x73\x74\x5F\x64\x69\x67\x69\x74″,”\x23\x6D\x75\x6C\x74\x69\x70\x6C\x69\x65\x72\x5F\x73\x65\x63\x6F\x6E\x64\x5F\x64\x69\x67\x69\x74″,”\x23\x6D\x75\x6C\x74\x69\x70\x6C\x69\x65\x72\x5F\x74\x68\x69\x72\x64\x5F\x64\x69\x67\x69\x74″,”\x23\x6D\x75\x6C\x74\x69\x70\x6C\x69\x65\x72\x5F\x66\x6F\x75\x72\x74\x68\x5F\x64\x69\x67\x69\x74″,”\x23\x6D\x75\x6C\x74\x69\x70\x6C\x69\x65\x72\x5F\x66\x69\x66\x74\x68\x5F\x64\x69\x67\x69\x74″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x66\x69\x72\x73\x74\x5F\x64\x69\x67\x69\x74″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x73\x65\x63\x6F\x6E\x64\x5F\x64\x69\x67\x69\x74″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x74\x68\x69\x72\x64\x5F\x64\x69\x67\x69\x74″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x66\x6F\x75\x72\x74\x68\x5F\x64\x69\x67\x69\x74″,”\x23\x66\x72\x65\x65\x5F\x70\x6C\x61\x79\x5F\x66\x69\x66\x74\x68\x5F\x64\x69\x67\x69\x74″,”\x20″,”\x69\x6E\x6E\x65\x72\x48\x54\x4D\x4C”,”\x2E\x62\x72\x5F\x30\x5F\x30\x5F\x35\x5F\x30″,”\x23\x77\x69\x6E\x6E\x69\x6E\x67\x73″,”\x23\x62\x61\x6C\x61\x6E\x63\x65″,”\x62\x61\x6C\x61\x6E\x63\x65″];

因此，除了使代码难以理解且难以理解之外，还有一些错误。

一个问题是大括号，例如// let's create data val df = Seq(("joe", "2017-03-29 2:23:38"), ("mike", "2017-03-29 3:53:38"), ("mary", "2017-03-29 11:03:38")) .toDF("name", "date") .select('name, to_timestamp('date) as "date") // Then, let's extract the hour and add your logic // (I'm not sure it is your exact logic, but you see the idea) df.withColumn("h", hour('date)) .withColumn("int", when('h >= 1 && 'h < 5, 1) .otherwise(when('h >= 5 && 'h < 10, 2) .otherwise(3))) .show +----+-------------------+---+---+ |name| date| h|int| +----+-------------------+---+---+ | joe|2017-03-29 02:23:38| 2| 1| |mike|2017-03-29 03:53:38| 3| 1| |mary|2017-03-29 11:03:38| 11| 3| +----+-------------------+---+---+，″和“。都应将它们全部替换为”或"。

然后，第一行声明一个变量'，随后代码尝试以_$_d9ef和$_d9ef和$d9ef的形式访问，只有最后一次访问才有效，其余的将失败。

最终的可执行代码为

_$_d9ef
