讓.Net驗證控件與自定義驗證合作無間

新建一個Page頁面，簡單的放一些控件

1. <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>  
2.         <asp:Button ID="Button1" runat="server"   Text="Button"    
3.             ValidationGroup="submit" CausesValidation="True"    
4.             onclick="Button1_Click" />  
5.         <input type="checkbox" id="checkbox" />我已閱讀注冊協議       
6.         <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"    
7.             ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="不能為空"    
8.             ValidationGroup="submit"></asp:RequiredFieldValidator>  

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server"   Text="Button" 
            ValidationGroup="submit" CausesValidation="True" 
            onclick="Button1_Click" />

            ValidationGroup="submit"></asp:RequiredFieldValidator>

1. <script type="text/javascript">   
2.         function test() {   
3.             var isCheck = document.getElementById('checkbox').checked;   
4.             if (isCheck) {   
5.           //Page_ClientValidate('submit'),這裡有不同的ValidGroup,所以Page_ClientValidate傳遞是指定的GroupName   
6.                 if (Page_ClientValidate('submit')) {

8.                     return true;
