ASP.NET页面加载中效果实现

/// 

/// 页面加载中效果
/// 
public static void initJavascript()
{
        HttpContext.Current.Response.Write(" ");
        HttpContext.Current.Response.Write("");
        HttpContext.Current.Response.Write("
");
        HttpContext.Current.Response.Write("
");
        HttpContext.Current.Response.Write("
页面正在加载中 ...
");
        HttpContext.Current.Response.Write("
 
");
        HttpContext.Current.Response.Write("
");
        HttpContext.Current.Response.Flush();
}

2.Page_Load方法中调用

 protected void Page_Load(object sender, EventArgs e)
 { 
     initJavascript();
 }

3.前台调用
