DevExpress与长连接冲突导致DevExpressAJax事件失效

最近公司要做一个长连接从服务器推送消息，网上找了一段代码

      function onload() {

          var isIE = !!window.ActiveXObject;

          if (isIE) {

              ifrpush = new ActiveXObject("htmlfile"); // 创建对象

              ifrpush.open(); //打开

             var ifrDiv = ifrpush.createElement("div"); //添加一个DIV

              ifrpush.appendChild(ifrDiv); //添加到 htmlfile

             ifrpush.parentWindow.Change = Change; //注册 javascript 方法

              ifrDiv.innerHTML = "<iframe src='Action/Socket.ashx'></iframe>"; //在div里添加 iframe

             ifrpush.close(); //关闭

              setInterval("IsLoaded()", 1000); //监视长链接状态

         } else {

              request = new window.XMLHttpRequest();

              responseDIV.innerHTML = "";

             var url = "Action/Socket.ashx";

             request.open("GET", url, true);

              request.onreadystatechange = NOTIEReadyStateChange;

              request.send(null);

          }

      }

结果的DevExpress的js方法名重复了

_aspxAttachEventToElement(window, "load", aspxClassesWindowOnLoad);
function aspxClassesWindowOnLoad(evt){
__aspxDocumentLoaded = true;
ASPxResourceManager.SynchronizeResources();
aspxGetControlCollection().Initialize();
_aspxInitializeScripts();
_aspxInitializeLinks();
_aspxInitializeFocus();
}
