asp.net - 如何停止验证组中的一系列验证器以在错误时停止触发？网

Question

一个文本框上有 3 个验证器，

asp:RegularExpressionValidator asp:RangeValidator asp:CompareValidator

一些输入会触发所有 3 个，我怎样才能在任何错误时停止触发其余的？

可能这可以帮助您..您可以拦截 ASP.Net 验证框架的 ValidatorValidate 方法，并根据任何给定的验证控件结果选择性地禁用您想要的验证器控件。

<asp:TextBox ID="tbText" runat="server"></asp:TextBox>

<asp:RegularExpressionValidator EnableClientScript="true" ValidationExpression="\d" ID="rang" runat="server" ControlToValidate="tbText" >sdfsdfsdfsdfsdfsd</asp:RegularExpressionValidator>
<asp:RangeValidator EnableClientScript="true" Type="Date" MinimumValue="10/10/2000" MaximumValue="10/10/2013" runat="server" ID="rang2" ControlToValidate="tbText" >23444444444444</asp:RangeValidator>
<asp:Button ID="btn" runat="server" Text="submit"/>



<script language="javascript">
    var oldValidatorValidate = ValidatorValidate;
    function MyValidatorValidate(val, validationGroup, event) {



        //first call the original one
        oldValidatorValidate(val, validationGroup, event);

        //Here you can check val.isvalid - e.g write your logic here, like check for the correct validator etc etc
        //alert(val.id + ":" + val.isvalid);
        if (!val.isvalid) {
            var myVal = document.getElementById('<%=rang2.ClientID %>');
            //ValidatorEnable(myVal, false);
        }





    }
    ValidatorValidate = MyValidatorValidate;
</script>
