如果多个脚本同时定时访问,容易引发脚本异常,没下就记下来了。
</ script > < script type = " text/javascript " > function WebForm_CallbackComplete_SyncFixed() { for (var i = 0 ; i < __pendingCallbacks.length; i ++ ) { callbackObject = __pendingCallbacks[ i ]; if (callbackObject && callbackObject.xmlRequest && (callbackObject.xmlRequest.readyState == 4 )) { if ( ! __pendingCallbacks[ i ].async) { __synchronousCallBackIndex = - 1 ; } __pendingCallbacks[i] = null ; var callbackFrameID = " __CALLBACKFRAME " + i; var xmlRequestFrame = document.getElementById(callbackFrameID); if (xmlRequestFrame) { xmlRequestFrame.parentNode.removeChild(xmlRequestFrame); } WebForm_ExecuteCallback(callbackObject); } } } window.onload = function(){ if ( typeof (WebForm_CallbackComplete) == " function " ) { WebForm_CallbackComplete = WebForm_CallbackComplete_SyncFixed; }} </ script >
