How to hide js code
这次给大家带来怎么隐藏js代码，隐藏js代码的注意事项有哪些，下面就是实战案例，一起来看一下。
好了，我们来看下代码吧。
(function(window) {
var rep = { // 替换用的数据，使用了4个零宽字符，数据量减少了一半。
'00': '\u200b',
'01': '\u200c',
'10': '\u200d',
'11': '\uFEFF'
};
function hide(str) {
str = str.replace(/[^\x00-\xff]/g, function(a) { // 转码 Latin-1 编码以外的字符。
return escape(a).replace('%', '\\');
});
str = str.replace(/[\s\S]/g, function(a) { // 处理二进制数据并且进行数据替换
a = a.charCodeAt().toString(2);
a = a.length < 8 ? Array(9 - a.length).join('0') + a : a;
return a.replace(/../g, function(a) {
return rep[a];
});
});
return str;
}
var tpl = '("@code".replace(/.{4}/g,function(a){var rep={"\u200b":"00","\u200c":"01","\u200d":"10","\uFEFF":"11"};return String.fromCharCode(parseInt(a.replace(/./g, function(a) {return rep[a]}),2))}))';
window.hider = function(code, type) {
var str = hide(code); // 生成零宽字符串
str = tpl.replace('@code', str); // 生成模版
if (type === 'eval') {
str = 'eval' + str;
} else {
str = 'Function' + str + '()';
}
return str;
}
})(window);大家可以通过最简单的代码例子进行测试一下，看看效果如何，也可以进一步优化，或者写成插件什么的，就当练习吧。。
虽然这个东西没什么实际用处，不过有时候玩玩还是不错的，可出面试题吓唬新人哦。。
