加了断点调试后台也运行Response.Write()这句话。可是运行的时候前台页面没有出现提示信息，直接跳转到softwareupgrade.aspx页面。为什么啊。我要是把Response.Redirect("softwareupgrade.aspx");这句话注释掉就会出现提示。为什么啊？
- C# code
private void IBSoftwareUpgrade_Click(object sender, System.Web.UI.ImageClickEventArgs e) { string sql="select * from softwareupgrade where sid='"+this.txtsid.Text+"'"; SqlConnection conn=new SqlConnection("uid=sa;pwd=sa;database=softwaremanage;server=."); conn.Open(); SqlCommand cmd=new SqlCommand(sql,conn); SqlDataReader reader=cmd.ExecuteReader(); if(reader.Read()) { Response.Redirect("softwareupgradesearch.aspx"); } else { Response.Write("<script language=javascript >confirm('此软件没有升级记录,是否添加?');</script>"); //this.IBSoftwareUpgrade.Attributes.Add("onclick","javascript:return confirm ('此软件没有升级记录，是否添加?')"); Response.Redirect("softwareupgrade.aspx"); } reader.Close(); conn.Close(); }------解决方案--------------------------------------------------------
Response.Write("<script language=javascript >confirm('此软件没有升级记录,是否添加?');</script>");
//this.IBSoftwareUpgrade.Attributes.Add("onclick","javascript:return confirm ('此软件没有升级记录，是否添加?')");
Response.Redirect("softwareupgrade.aspx");
=========>
Response.Write("<script>if(confirm('此软件没有升级记录,是否添加')){window.location.href='softwareupgrade.aspx';}
------解决方案--------------------------------------------------------
Response.Write和Response.Redirect一起用的时候就会这样，
你可以只用response.write("<script language=javascript >confirm('此软件没有升级记录,是否添加?');window.location.href='softwareupgrade.aspx'</script>");来实现
------解决方案--------------------------------------------------------
Response.Redirect("softwareupgrade.aspx");
======
有这句就直接过去了.
跳转可以用客户端跳转
- JScript code
window.location.href='softwareupgrade.aspx'
