我在JavaScript中有这个代码:
[(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]
在控制台中,它将返回
Array [ "filter" ]
我如何解码许多与上述文本类似的文本？例如:
[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]][([][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+
(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+
([][[]]+[])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[+!+[]]+([][[]]+[])[+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+(!![]+[])[+!+[]]]
我想看一下普通的剧本.
Math.acos(Math.cos(30))不会返回30,但Math.acos(Math.cos(0.7))会返回0.7 ......我怎么能正确地做到？
我已经生成了libBox2D.a. 现在我想把它导入到C++项目中，但我不知道怎么做。如何libBox2D.a使用 CMake 将我的项目导入到我的项目中？
我的 C++ 项目包括Boost和WebSocket++库。我阅读了需要添加-lws2_32到 gcc 命令的其他主题，但我使用了 CLion，但我不知道如何修复它。
安慰：

我该做什么？
CSS:
input:focus ~ p {
color: red;
}
HTML:
<div>
<input type="text" />
</div>
<p>Please click on the input!</p>
我想制作p红色(仅限CSS),但输入是div...
可能吗？如何？
我已经加入了Boost 1.61.0.我的C++项目有类似的问题,我添加target_link_libraries(WsServer ws2_32)并修复了它.然后,出现了另一个错误.代码:WebSocket ++示例:simple_broadcast_server.cpp.我怎么解决它？

如您所见,此函数接受所有变量类型.是否可以过滤类型名称？我想只允许uint8_t, int8_t, uint16_t, int16_t etc. + float and double too吗？我不想做10个if陈述,因为它看起来不干净.
