在vb.net中使用脚本管理器动态追加时间

Question

I am trying to append time dynamically in vb.net using below code but i always got error "missing ) after argument list" Please let me know where i am wrong.

Dim st As String = "09:00 am"
        Dim ed As String = "11:00 am"

        Dim start As DateTime = DateTime.ParseExact(st, "hh:mm tt", Nothing)
        Dim [end] As DateTime = DateTime.ParseExact(ed, "hh:mm tt", Nothing)
        Dim interval As Integer = 30
        Dim lstTimeIntervals As New List(Of String)

        For i As Integer = 1 To 5
            lstTimeIntervals.Add(start.ToString("hh:mm tt"))
            start = start.AddMinutes(interval)


            Response.Write(start + "<br/>")
            ScriptManager.RegisterStartupScript(Page, Page.GetType(), "time" + i.ToString, "alert('h');$('.cnt').append(" + start.TimeOfDay.ToString + ");", True)


        Next

ERROR

$('.cnt').append( 09:30:00 ); //here in bold portion of time it is giving error missing ) after argument list $('.cnt').append( 10:00:00 )

把时间用引号引起来：

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "time" + i.ToString, "alert('h');$('.cnt').append('" + start.TimeOfDay.ToString + "');", True)
