任何人有任何想法吗?
当运行以下代码时,会发生上述错误:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
在此块内:
<script language="javascript" type="text/javascript">
var postBackElement;
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(InitializeRequestHandler);
function InitializeRequestHandler(sender, args) {
//set the postBackElement
postBackElement = args.get_postBackElement();
}
最佳答案
如果要使用RequestCompleted
事件,则需要处理它:
function RequestCompleted(sender, args) {
// Do what you need to do here
}
如果您不需要处理事件,只需从标记中删除此行:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
