Question

这是我的表单中我的文本框的示例，带有自定义验证，我想禁用验证器：

 <asp:textbox id="txtFirstName" runat="server" /></td><td>
        <script language ="javascript">
            function requireFirstName(source, args) {

                if (document.getElementById("<%=txtFirstName.ClientID %>").value =="") {
                    args.IsValid = false;
                }
                else {
                    args.IsValid = true;
                }
            }
      </script>
        <asp:CustomValidator ID="RequiredValidator1" runat="server" 
            ErrorMessage="You must enter your first name." 
             ForeColor="Red" clientvalidationfunction="requireFirstName"
            ></asp:CustomValidator>

这是我之前的按钮：

<asp:Button ID="PreviousButton" runat="server"  
                Text="<-- Back to Instructions" OnClick="btnBack_Click" 
                class="previous"   />
            <script type="javascript">
             document.getElementById("<%=PreviousButton.ClientID%>").disableValidation = true;
            </script>

这不起作用，仍然有验证器。帮助

Answer 1

<asp:Button ID="PreviousButton" runat="server" CausesValidation="false"  
                Text="<-- Back to Instructions" OnClick="btnBack_Click" 
                class="previous" EnableClientScript="false"   />

Answer 2

尝试将CausesValidation设置为false。

<asp:Button ID="PreviousButton" runat="server" Text="<-- Back to Instructions" OnClick="btnBack_Click" class="previous" CausesValidation="false" />

上一个按钮显示验证
