alert 跳出提示訊息的幾種方法

1090807更新

//要引用JavaScriptSerializer類別 , NET 3.5 以上版本才有

using System.Web.Script.Serialization;

 try

{   

}

catch(Exception ex)

{

    var message = new JavaScriptSerializer().Serialize(ex.Message.ToString());

    var script = string.Format("alert({0});", message);

    ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "", script, true);

}

1.ClientScript.RegisterStartupScript(GetType(),"message","<script>alert('第一種方式,不會有白色底!');</script>");

2.HttpContext.Current.Response.Write("<script>alert('第二種方式,有白色底!')</script>");

1070412測試可用下面這行
HttpContext.Current.Response.Write("<script>alert('!!! 訊息錯誤 !!! : " + err.Message + "');</script>");
                 
3.public static void Show(System.Web.UI.Page page, string msg)
    {
        page.ClientScript.RegisterStartupScript(page.GetType(), "message", "<script language='javascript' defer>alert('" +  msg.ToString() + "');</script>");
    }
  Show(this, "第三種方式，不會有白色底!");

4.Response.Write("<script>alert('第四種方式，有白色底!')</script>");

5.window.showModalDialog('XXX.aspx', '', 'dialogWidth:429px;dialogHeight:200px;location:no,menubar:no,toolbar:no,status:no');

6.Page.clientscript.registerstartupscript(this.gettype(), "", "<script>window.open('../issue/issueallcomment.aspx');</script>");

7.如果使用ajax控制項的話
System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "opennewwindow", "alert('彈出來的內容!');", true);

8.在頁面body的最後一行個控制項，在給這個給控制項值，如:
label.Text="<script>alert('彈出來的內容!'); </script> ";

9.可以傳參數，注意  '  跟  "  的排列
 string strtmp = "if (confirm('此病歷號碼尚未收案，是否要新增收案')) {window.location.href = 'Default2.aspx?patno=" + txtselect.Text +"';}";
                            ClientScript.RegisterStartupScript(GetType(), "ScriptKey",strtmp, true);
 10.  ClientScript.RegisterClientScriptBlock(this.GetType(), "ScriptBlock", "alert('RegisterClientScriptBlock OK!!')", true);

11    ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('" + values + "');</script>", true);

注意  " 雙引號跟 ' 單引號 ，錯誤會造成無法使用
      ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('帳號驗證結果 : 錯誤 " + strcheck + "');</script>");

1070412測試可用下面這行
   ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert(" + "'" + Lbl_msg.Text + "'" +");</script>");// ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('存檔錯誤:'" + Lbl_msg.Text + "');</script>");
         

//下面是使用web服務的 alert

        string strid = TextBox1.Text.Trim();
        string strpw = TextBox2.Text.Trim();
        ServiceReference1.ServiceSoapClient ws = new ServiceSoapClient();
        if (ws.CheckHISAccount(strid, strpw) == 0)
        {
            ws.Close();
            //基本的 alert
            // ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('帳號驗證結果 : 正確 ');</script>");

            //轉址的 alert，斷行 \\n
            //ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('帳號驗證結果 : 正確\\n按 確定 轉往 Pacs');location.href='http://192.168.xxx.xxx';</script>");
           
            //確認再轉址的alert
            ClientScript.RegisterStartupScript(GetType(), "message", "<script>if (confirm('帳號驗證結果 : 正確\\n\\n按 確定 轉往 Pacs 視窗')) {window.location.href ='http://192.168.xxx.xxx';}</script>");
           

//確認再轉址的alert ScriptManager
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "alert", "alert('修改成功!'); location.href='Default.aspx';", True)

            //另開新視窗
            // ClientScript.RegisterStartupScript(GetType(), "message", "<script>window.open('http://192.168.xxx.xxx','新視窗的名稱');</script>");
          
            //純.net轉址
           // Response.Redirect("http://192.168.xxx.xxx");//登入ok後，轉址去pacs視窗
        }
        else {
            string strcheck = ws.CheckHISAccount(strid, strpw).ToString();
            ws.Close();
            //下面script注意 " 跟 ' 符號的包圍的前後順序
            ClientScript.RegisterStartupScript(GetType(), "message", "<script>alert('帳號驗證結果 : 錯誤 " + strcheck + "');</script>");
        }
