Question

当用户点击登录按钮时，我想调用login.ascx文件中的javascript函数。

以下是login.ascx代码的代码：

              <div class="dnnFormItem">
                <asp:label id="lblLogin" runat="server" AssociatedControlID="cmdLogin" CssClass="dnnFormLabel" />
               <asp:LinkButton id="cmdLogin" resourcekey="cmdLogin" cssclass="dnnPrimaryAction" text="Login" runat="server"/>
               <script type="text/javascript">
/*globals jQuery, window, Sys */
(function ($, Sys) {
    function setUpLogin() {
        var actionLinks = $("a[id$=cmdLogin]");
        actionLinks.click(function () {
            if ($(this).hasClass("dnnDisabledAction")) {
                return false;
            }

            actionLinks.addClass("dnnDisabledAction");
        });
    }

    $(document).ready(function () {
        setUpLogin();
        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(function () {
            setUpLogin();
        });
    });
}(jQuery, window.Sys));

以下是login.ascx中的javascript代码，我想在用户点击登录按钮时调用它。

function myTestFun() {





    //var  _currentUser =

    //           DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo();

    var userName = '<%=username%>';

    var fname = '<%=firstnm%>';

    var userinfo= {

        "Usr_Username": userName,
         "Usr_Email": "",
         "Usr_FirstName": fname
    };

     localStorage.setItem('GoDashProUser', JSON.stringify(GoDashProUser));
   }
   </script>

以下是使用C＃的代码隐藏文件：

         private void OnLoginClick(object sender, EventArgs e)
    {
        ClientScriptManager cs = Page.ClientScript;

            if (loginStatus == UserLoginStatus.LOGIN_USERNOTAPPROVED)
            {
                message = "UserNotAuthorized";
            }
            else
            {
                authenticated = (loginStatus !=UserLoginStatus.LOGIN_FAILURE);
            }

            //Raise UserAuthenticated Event
            var eventArgs = new UserAuthenticatedEventArgs(objUser, txtUsername.Text, loginStatus, "DNN")
                                {
                                    Authenticated = authenticated, 
                                    Message = message,

                                };
            //string script = "<script type=\"text/javascript\"> myTestFun(); </script>";
            //ClientScript.RegisterClientScriptBlock(this.GetType(), "myscript", script);
           // cs.RegisterStartupScript(GetType(), "myTestFun", "myTestFun();", true);
            //Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", "myTestFun()", true);
            ScriptManager.RegisterClientScriptBlock(this.Page, typeof(UpdatePanel), UniqueID, "myTestFun();", true);

            firstnm = objUser.FirstName;

            OnUserAuthenticated(eventArgs);
        }
    }

我已经尝试了大多数可能的选项来调用javascript函数，但它不会调用。我想调用javascript函数将数据保存到本地存储中，并且还想传递userinfo的值。

请告诉我一些方法。谢谢。
