.NET 解决重复提交问题

1.在ASPX页面下加一个隐藏域         <asp:HiddenField ID="HidSign" runat="server" />

2.cs代码

?

protected void Page_Load( object sender, EventArgs e)         {             if (!IsPostBack)             {                  UpdateSign();             }          }                static string rp_GoodsEdit;         public void UpdateSign()         {             HidSign.Value = DateTime.Now.ToString( "ffffff" );             rp_GoodsEdit = HidSign.Value;         }     //

?

protected void btnSave_Click( object sender, EventArgs e)         {             if (rp_GoodsEdit == HidSign.Value)             {                 UpdateSign();             }             else             {                 this .ClientScript.RegisterStartupScript( this .GetType(), "startup" , "alert('请勿重复提交！');self.parent.tb_remove('reload');" , true );                 UpdateSign();                 return ;             } ................ }
