Html 使用引导验证特定div

我有两个主要分区，一个用于登录，另一个用于注册。 我只想在用户单击“注册”按钮时验证注册div，当用户单击“登录”按钮时，不应执行注册验证。 这是我的html代码

<form id="form1" runat="server">

            <%--Login div--%>
            <div class="navbar-form navbar-right col-md-9">
                <div class="input-group" style="margin-top: 10px;">
                    <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
                    <asp:TextBox ID="txtMobleNoLogin" runat="server" class="form-control" placeholder="Mobile Number"></asp:TextBox>
                </div>
                <div class="input-group" style="margin-top: 10px;">
                    <span class="input-group-addon"><i class="glyphicon glyphicon-lock"></i></span>
