在 asp.net 内容页面中单击按钮时 jQuery 代码不起作用

Question

这是我的母版页指令

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="DashMaster.master.cs" Inherits="TNC.DashMaster" %>

这是我的内容页面指令

<%@ Page Title="Dashboard Page" Language="C#" MasterPageFile="~/DashMaster.Master" AutoEventWireup="true" CodeBehind="Dashboard.aspx.cs" Inherits="TNC.dash.Dashboard" %>

在我的内容页面中，我有 3 个标签 { 个人资料标签、图片标签、更改密码标签}
当我更新我的个人资料信息时，它会更新到数据库文件，但更新后我想通过使用后面的代码显示消息 Profile info updated Successfully..

protected void btnDashProfileSubmit_Click(object sender, EventArgs e)
    {
        int i = _editUserPresenter.UpdateProfile(Convert.ToInt64(txtdashuserID.Text),
                                         txtdashusername.Text,
                                         txtdashfirstname.Text.Trim(),
                                         txtdashlastname.Text.Trim(),
                                         ddlGender.SelectedValue.ToString(),
                                         txtdashEmailID.Text,
                                         txtdashContactNo.Text.Trim(),
                                         txtdashdesignation.Text.Trim(),
                                         txtdashqualification.Text.Trim());
        if (i > 0)
        {
            //calling Display you can find this method below
            Display(Convert.ToInt64(txtdashuserID.Text));
            ScriptManager.RegisterStartupScript(this, GetType(), "editProfile", "$('.alert-success').show(); $('.alert-success').html('Profile Update Successfully...'); ", true);
            Response.Redirect("Dashboard.aspx?userID=10000000022&username=srikanth442#divprofile");
        }
        else
        {
            ScriptManager.RegisterStartupScript(this, GetType(), "editProfileFail", "$('.alert-danger').show(); $('.alert-danger').html('Profile Update Fail. Please Try Again');", true);
            Response.Redirect("Dashboard.aspx?userID=10000000022&username=srikanth442#divprofile");
        }
    }

我把这个显示方法叫做几个地方

public void Display(Int64 UserID)
        {
            DataSet ds = _userServices.GetUserByUserID(UserID);
            string Username = Extension.Decrypt(ds.Tables[0].Rows[0]["username"].ToString());
            Session["username"] = Username;
            _userSession.LoggedIn = true;
            _userSession.Username = Username;

            foreach (DataRow dw in ds.Tables[0].Rows)
            {
                txtdashuserID.Text = dw["userid"].ToString();
                txtdashusername.Text = Username;
                txtdashfirstname.Text = dw["firstname"].ToString();
                txtdashlastname.Text = dw["lastname"].ToString();
                txtdashEmailID.Text = dw["emailid"].ToString();
                txtdashContactNo.Text = dw["phone"].ToString();
                txtdashdesignation.Text = dw["designation"].ToString();
                txtdashqualification.Text = dw["qualification"].ToString();
                if (dw["accountype"].ToString() == "1")
                {
                    lbldashAccountType.Text = "Free";
                }
                if (dw["usertype"].ToString() == "1")
                {
                    lbldashUserType.Text = "General";
                }
                if (dw["roles"].ToString() == "1")
                {
                    lbldashRole.Text = "User";
                }
                Label lblUsername = (Label)Master.FindControl("lbldashfullname");
                Label lblAccountCreatedDate = (Label)Master.FindControl("lbldashAccountCreatedon");
                Label lblAccountUpdatedDate = (Label)Master.FindControl("lbldashprofileupdate");
                Session["username"] = Username;
                Session["AccCreateDate"] = String.Format("{0:dddd, dd MMM yyyy}", dw["account_create_date"]);
                Session["AccUpdatedDate"] = String.Format("{0:dddd, dd MMM yyyy}", dw["update_account_date"]);
            }
        }

试试这个

ClientScript.RegisterStartupScript(typeof(Page), "key",
             "<script type=\"text/javascript\">" + "$('.btnDashProfileSubmit').live(\"click\", function () {$('.alert-success').show(); $('.alert-success').html('Profile Update Successfully...');});" + "</script>"
             );
