推荐答案

是的，您可以使Web方法类似..您可以创建Web服务来调用服务器端代码

yes, you can make web method like.. you can create web service to call to server side code

[WebMethod]
public static String SetName(string name)
{
    return "Your String"
}

然后像这样调用javascript.

and then call in javascript like..

PageMethods.SetName(parameterValueIfAny, onSuccessMethod,onFailMethod);

这也是必需的

this also required

<asp:scriptmanager id="ScriptMgr" runat="server" enablepagemethods="true" xmlns:asp="#unknown"> </asp:scriptmanager>
