这个jQuery怎么破？
How can this jQuery be decoded?
我想知道这个 jQuery 文件是如何编码的，我该如何解码？

澄清问题： 上面的代码用十六进制混淆了，如何取消混淆这样的 jQuery 代码以使代码可读。
转换十六进制 -> utf8，然后用数组中的值替换 _0xc702 中的所有匹配项。然后替换 \["([a-zA-Z0-9]+)"\] -> .。然后快速扫描并给出语义变量名称。

这是我用来反混淆的一些代码：
main.js
var fs = require('fs');
var name = '_0xc702';
var vars;
// Use eval for quick hex -> utf8 strings
eval('vars=' + fs.readFileSync('vars.json', 'utf8'));
var input = fs.readFileSync('input.js', 'utf8');
vars.forEach(function(value, key) {
input = input.replace(new RegExp(name + '\['+key+'\]', 'g'), '"'+ value +'"');
});
input = input.replace(/\["([a-zA-Z0-9]+)"\]/g, '.');
console.log(input);
vars.json

澄清问题： 上面的代码用十六进制混淆了，如何取消混淆这样的 jQuery 代码以使代码可读。
转换十六进制 -> utf8，然后用数组中的值替换 _0xc702 中的所有匹配项。然后替换 \["([a-zA-Z0-9]+)"\] -> .。然后快速扫描并给出语义变量名称。

var options = {

这是我用来反混淆的一些代码：
main.js
var fs = require('fs');
var name = '_0xc702';
var vars;
// Use eval for quick hex -> utf8 strings
eval('vars=' + fs.readFileSync('vars.json', 'utf8'));
var input = fs.readFileSync('input.js', 'utf8');
vars.forEach(function(value, key) {
input = input.replace(new RegExp(name + '\['+key+'\]', 'g'), '"'+ value +'"');
});
input = input.replace(/\["([a-zA-Z0-9]+)"\]/g, '.');
console.log(input);
