我已经更新了DOMAssistant库的代码，对我来说很好

var domReady = (function (){
  var arrDomReadyCallBacks = [] ;
  function excuteDomReadyCallBacks(){
       for (var i=0; i < arrDomReadyCallBacks.length; i++) {
         arrDomReadyCallBacks[i]();
       }
       arrDomReadyCallBacks = [] ;
  }

  return function (callback){
    arrDomReadyCallBacks.push(callback);
     /* Mozilla, Chrome, Opera */
      if (document.addEventListener ) {
          document.addEventListener('DOMContentLoaded', excuteDomReadyCallBacks, false);
      }
    /* Safari, iCab, Konqueror */
    if (/KHTML|WebKit|iCab/i.test(navigator.userAgent)) {
        browserTypeSet = true ;
        var DOMLoadTimer = setInterval(function () {
            if (/loaded|complete/i.test(document.readyState)) {
                //callback();
                excuteDomReadyCallBacks();
                clearInterval(DOMLoadTimer);
            }
        }, 10);
    }
    /* Other web browsers */

    window.onload = excuteDomReadyCallBacks;
}
})()
