播放声音使用JavaScript与UpdatePanel的

我有以下Asp.net代码：播放声音使用JavaScript与UpdatePanel的

的问题是，当计时器滴答以每30秒和GridView填充的JavaScript代码不执行！并没有播放声音。

我也尝试过SoundPlayer类，但不能在服务器端工作任何人都可以提供给我一个解决方案吗？

和后面的代码是：

protected void Timer1_Tick(object sender, EventArgs e) 

     { 
      orderDB.LogState("Time Tick"); 
      if (Session["UserID"] != null) 
      {

      } 
      else 
      { 
       Response.Redirect("~/login.aspx"); 
      } 
     } 

private void FillDataGrid(int UserID) 
{ 

    Orders = orderDB.GetOrdersByUser(UserID); 
    orderDB.LogState("Select: " + DateTime.Now.ToString() + "\t" + Request.UserHostAddress + "\t" + Session.SessionID + "\t" + Session["UserID"].ToString()); 

    if (Orders == null) 
     Response.Redirect("~/login.aspx"); 

    DataTable Table = new DataTable(); 

    Table.Columns.Add("ID", System.Type.GetType("System.String")); 
    Table.Columns.Add("Name", System.Type.GetType("System.String")); 
    Table.Columns.Add("Address", System.Type.GetType("System.String")); 
    Table.Columns.Add("Number", System.Type.GetType("System.String"));

    Table.Columns.Add("Restaurant", System.Type.GetType("System.String")); 
    Table.Columns.Add("Branch", System.Type.GetType("System.String")); 

    for (int i = 0; i < Orders.Count; i++) 
    { 
     object[] myRow = new object[10]; 
     myRow[0] = Orders[i].GetId(); 
     myRow[1] = Orders[i].GetOwner();

     myRow[8] = Orders[i].GetResName(); 
     myRow[9] = Orders[i].GetBranchName(); 

     Table.Rows.Add(myRow); 
    } 

    orderDB.LogState("Table Rows Count: " + Table.Rows.Count); 
    GridViewOrders.DataSource = Table; 
    GridViewOrders.DataBind(); 

    string sSelectedAudio = Server.MapPath("home.wav"); 
    if (GridViewOrders.Rows.Count != 0) 
    { 
     playSound(sSelectedAudio); 
     orderDB.LogState("Sound Played: " + GridViewOrders.Rows.Count); 
    } 
    else 
    { 
     orderDB.LogState("Empty Grid View: " + GridViewOrders.Rows.Count); 
    } 
} 

private void playSound(string path) 
{ 
    string PlaySound = "<embed src=\"" + path + "\" autostart=\"true\" hidden=\"true\"></embed>"; 
    Response.Write(PlaySound); 
}

这可能是造成问题的Response.Write。尝试使用一个占位符控件，然后添加一个HtmlGenericControl将其与标记中嵌入标签即

HtmlGenericControl sound = new HtmlGenericControl("<embed src=\"" + path + "\" 
      autostart=\"true\" hidden=\"true\"></embed>"); 
    ucPlaceHolder.Controls.Add(sound);

确保占位控制withing在UpdatePanel的ContentTemplate您正在使用
