<input id="accept-terms" type="checkBox" class="required"/> 
            <label for="accept-terms"> I accept the <asp:HyperLink ID="termsLink" runat="server" Target="_blank">terms and condtions</asp:HyperLink> of sale.</label>
            <label for="accept-terms" class="error-text">You must accept the terms and conditions before purchasing</label>

我得到这个错误：

Uncaught TypeError: Cannot call method 'getAttribute' of undefined
