• 异步加载脚本，并触发加载完成时的回调函数

  function async(u, c) {
  var d = document, t = 'script',
    o = d.createElement(t),
    s = d.getElementsByTagName(t)[0];
  o.src = '//' + u;
  if (c) { o.addEventListener('load', function (e) { c(null, e); }, false); }
  s.parentNode.insertBefore(o, s);
  }

  usage

  async('snapabug.appspot.com/snapabug.js', function() {
  SnapABug.init('XXXXX-XXXXX-XXXXX-XXXXX-XXXXX');
  });
