        <script type = "text/javascript">
            function GetSQLTable() {
                $.ajax({

                        alert(response.d);
                    }
                });
            }
            function OnSuccess(response) {
                alert(response.d);
            }
            window.onload = GetSQLTable
        </script> 
    </head>
    <body style = "font-family:Arial; font-size:10pt">
        <form id="form1" runat="server">
            <div>
                <asp:TextBox ID="txtUserName" runat="server" visible="True"></asp:TextBox>
                <asp:TextBox ID="txtTerminalIP" runat="server" visible="True"></asp:TextBox>
            </div>
        </form>
    </body>
</html>

必须显示asp.net文本框（txtusername和txtterminalip）才能使其正常工作。我可以使用任何看不见的控件吗？即我不想在网页上显示用户名和IP地址。

Answer 1

使用css display:none;

脏样品

<div>
    <asp:TextBox ID="txtUserName" runat="server" style="display:none;"></asp:TextBox>
    <asp:TextBox ID="txtTerminalIP" runat="server" style="display:none;"></asp:TextBox>
</div>

更好的样本

<div class="i_want_to_hide">
    <asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
    <asp:TextBox ID="txtTerminalIP" runat="server"></asp:TextBox>
</div>

CSS

.i_want_to_hide > input {
    display: none;
}

Answer 2

只需使用HiddenField

即可

表示用于存储未显示值的隐藏字段。

示例用法：

<asp:HiddenField ID="txtUserName" Value="YourValue" />
<asp:HiddenField ID="txtTerminalIP" Value="YourValue" />

访问隐形属性
