补充 history 方法

var _wr = function(type) {
   var orig = history[type];
   return function() {
       var rv = orig.apply(this, arguments);
      var e = new Event(type);
       e.arguments = arguments;
       window.dispatchEvent(e);
       return rv;
   };
};

history.pushState = _wr('pushState');
 
history.replaceState = _wr('replaceState');
 
window.addEventListener('replaceState', function(e) {
  console.log('THEY DID IT AGAIN! replaceState 111111');
});

window.addEventListener('pushState', function(e) {
  console.log('THEY DID IT AGAIN! pushState 2222222');
});
