使用说明与常见问题How-to & FAQ
「JS eval 解包」是什么？What is the JavaScript Unpacker tool?
还原用 Dean Edwards p.a.c.k.e.r（eval(function(p,a,c,k,e,d)) 形式）压缩的 JavaScript 代码。纯文本解析，不执行任何代码，本地运行。Decode JavaScript packed with Dean Edwards p.a.c.k.e.r (the eval(function(p,a,c,k,e,d)) form) by pure text parsing — no code is executed, all local.
如何使用「JS eval 解包」？How do I use the JavaScript Unpacker tool?
在「JS eval 解包」中，按需设置点击「解包」、「复制」按钮即可。In the JavaScript Unpacker: Click "Unpack", "Copy".
支持哪些压缩格式？Which packed formats are supported?
支持最常见的 Dean Edwards p.a.c.k.e.r（eval(function(p,a,c,k,e,d){…}) 形式，2–62 进制，可连续解多层）。其他混淆方式可能无法还原。It supports the common Dean Edwards p.a.c.k.e.r form (eval(function(p,a,c,k,e,d){…}), radix 2–62, multiple layers). Other obfuscation schemes may not be recoverable.
会执行被解包的代码吗？Does it run the packed code?
不会。本工具只用正则读取打包参数（源码模板、进制、词表），按 packer 的编码规则做文本替换来还原源码，全程不调用 eval，也不执行粘贴的任何代码。参数里如果夹带表达式，会提示无法解析而不是运行它。No. It reads the packer arguments (template, radix, word list) with a regular expression and rebuilds the source by text substitution following the packer's encoding rules — eval is never called and none of the pasted code runs. If the arguments contain expressions, it reports that they cannot be parsed instead of running them.
代码或数据会被上传吗？Is my code or data uploaded?
不会。「JS eval 解包」完全用 JavaScript 在本地运行，适合处理含有密钥、内部接口等敏感内容的数据。No. The JavaScript Unpacker runs entirely in local JavaScript, so it is safe for data containing keys or internal endpoints.
