页面操作完成时,显示提示信息并倒计N秒后跳转

1. 当前页,在后台代码往前台输出(注册)脚本的方式

   A:一般操作成功后提示(这里直接用Response.Write输出了,也可以使用Page的ClientScript对象的RegisterStartupScript方法)

protected   void  Button1_Click( object  sender, EventArgs e)
    {
        
string  yourUrl  =   " http://www.baidu.com " ;
        
string  yourMsg  =   " 操作已成功 " ;
        StringBuilder js 
=   new  StringBuilder( " <script language=\ " javascript\ " > " )
                .Append(
" document.write(\' "   +  yourMsg  +   " \'); " )
                .Append(
" var timeSpan = 10; setInterval(\ " Redirect()\ " ,1000); " )
                .Append(
" function Redirect(){  if(timeSpan == 0){ " )
                .Append(
" window.location.href=\ "" +yourUrl+ " \ " ; }else{ " )
                .Append(
" document.body.innerHTML = \ " 倒数\ " +(timeSpan--)+\ " 秒\ " ;}} " )
                .Append(
" </script> " );
        Response.Write(js.ToString());
    }

   B:异常处理 发生时提示

try
            {
                
int .Parse( " hello " );
            }
            
catch  (Exception ex)
            {
                StringBuilder js 
=   new  StringBuilder( " <script language=\ " javascript\ " > " )
                .Append(
" document.write(\' "   +  ex.Message  +   " \'); " )
                .Append(
" var timeSpan = 10; setInterval(\ " Redirect()\ " ,1000); " )
                .Append(
" function Redirect(){  if(timeSpan == 0){ " )
                .Append(
" window.location.href=\ " http: // www.baidu.com\"; }else{")
                .Append( " document.body.innerHTML = \ " 倒数\ " +(timeSpan--)+\ " 秒\ " ;}} " )
                .Append(
" </script> " );
                Response.Write(js.ToString());
            }

 

2. 跳转到另外一页(带需要的参数及值),然后在新页中处理

    A:使用JS,可以参考一中的脚本,用js读取参数就可以了

    B:如果无参数传递,可以考虑在<head></head>里插入
        <meta http-equiv="refresh" content="等待秒数;url=跳转地址">
