Execute JavaScript function in code behind multiple times using for loop in ASP.Net

Hi mukesh1,

I have checked its working on master page. You need to place the script inside the body tag before the ContentPlaceHolder. So that you can use the showpop method in each child page.

To show all msg refer the below code.

As per the documentation, each startup script is uniquely identified by its key and its type. Scripts with the same key and type are considered as duplicates. Add unique values to each key like this.

C#

protected void Page_Load(object sender, EventArgs e)
{
    for (int i = 0; i < 3; i++)
    {
        ScriptManager.RegisterStartupScript(this, typeof(Page), "Alert" + i, "<script>showpop('" + "Description " + (i + 1) + "','" + "title " + (i + 1) + "')</script>", false);
    }
}

ok, thanks sir.

C#

DataSet ds = sql.getds("select title from admin_notification ");
Label1.Text = ds.Tables[0].Rows.Count.ToString();
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
    ScriptManager.RegisterStartupScript(this, typeof(Page), "Alert" + i, "<script>showpop('" + ds.Tables[0].Rows[i]["title"].ToString()  + "','" + "title"  +"')</script>", false);
}

Script

   <script type="text/javascript">         
       function showpop(msg, title) {
           toastr.options = {
               "closeButton": false,
               "debug": false,
               "newestOnTop": false,
               "progressBar": true,
               "positionClass": "toast-bottom-left",
               "preventDuplicates": true,
               "onclick": null,
               "showDuration": "300",
               "hideDuration": "1000",
               "timeOut": "120000",
               "extendedTimeOut": "1000",
               "showEasing": "swing",
               "hideEasing": "linear",
               "showMethod": "fadeIn",
               "hideMethod": "fadeOut"
           }
           // toastr['success'](msg, title);
           var d = Date();
           var count = document.getElementById("Label1").value;
          
           toastr.success(msg, title);
           return false; 
       }
    </script>
