  if (!hostname) throw new Error('vhost hostname required');
  if (!server) throw new Error('vhost server required');
  
  var regexp = new RegExp(
    '^' + hostname.replace(/[^*\w]/g, '\\$&').replace(/[*]/g, '(?:.*?)') + '$',

用JS计算字符所占字节数 
/**
 * 计算字符串所占的内存字节数，默认使用UTF-8的编码方式计算，也可制定为UTF-16
 * UTF-8 是一种可变长度的 Unicode 编码格式，使用一至四个字节为每个字符编码
 *
 * 000000 - 00007F(128个代码)      0zzzzzzz(00-7F)                             一个字节
 * 000080 - 0007FF(1920个代码)     110yyyyy(C0-DF) 10zzzzzz(80-BF)             两个字节
 * 000800 - 00D7FF
 * 00E000 - 00FFFF(61440个代码)    1110xxxx(E0-EF) 10yyyyyy 10zzzzzz           三个字节

在一个元素节点生成一个锁，保证在没有解锁的时候回调不会执行!

源码

(function ($){
  $.fn.sync = function (lock, fn){
    // 初始化参数
    fn = arguments.length === 1 ? lock : fn;
    fn = typeof lock === 'function' ? fn : $.noop;
    lock = lock && typeof lock === 'string' ? lock : 'default';
    lock = 'data-sync-' + lock;
