基本上，当您需要使用jQuery进行客户端调用时，您正在使用POST进行服务器请求.这是如何执行此操作的说明:

Basically, you are doing a server-request using a POST when you need to use jQuery to do a client-side call. Here is an explanation of how to do this:

请使用AJAX.如果使用AJAX(ScriptManager，UpdatePanel，Contenttemplate)，则页面无法刷新.

将您的控件放在ContentTemplate
中

Please use AJAX. If you use AJAX (ScriptManager, UpdatePanel, Contenttemplate) the Page cannot refresh.

Place your Controls here within ContentTemplate

<asp:ScriptManager ID="SavedScriptManager" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="savedUpdatePanel" runat="server">
    <ContentTemplate>

如果在txtUsername文本框中输入用户名后我没错，那么您要显示该用户的名称，因为您已经放置了AutoPostback=true.哪个是对的.但是在这种情况下，您需要用户名而不刷新页面.

为避免页面刷新，请使用updatepanel

If I am not wrong after entering Username in your txtUsername Textbox, you want to display the name of that User, for that you had put the AutoPostback=true. which is right. but In this scenario you want the username without refreshing the page.

For avoiding page refresh use updatepanel
