对以下js代码进行反混淆破解 var version_ = jsjiamicomv7; var _0x123e5b = _0x9f4c; function_0x49e973 _0x114c33 _0x2ae680 _0x2cbfe5 _0x257391 _0x18d12d _0x2d62f9 return _0x49e973 = _0x49

说明：

代码中有一段混淆的函数，通过对该函数进行反混淆，得到其中的执行逻辑。

函数中有一个内部函数，该函数通过字符串拼接和字符编码转换生成一段代码，然后将这段代码进行执行。

该段代码使用一个while循环，每次循环中通过try-catch语句模拟了一些数值的运算，然后从一个数组中提取一个字符，并根据一些逻辑（包括比较、替换等操作）来判断是否继续循环。

最终得到的字符就是原来被混淆的字符串。

最后，代码通过document对象的getElementById方法获取一个元素，并将其innerHTML设置为空字符串。
