在ASP.NET中使用Customvalidator出现问题

问题描述：

我正在尝试验证手机号码，如果手机号码大于10，则会给出错误或警告，这是我的代码:

i am trying to validate mobile number if mobile number is greater than 10 it give error or alert here is my code:

function check()
     {
var pattern=/^[A-Za-z0-9]{10}$/;

     var regexp = new RegExp(pattern);
     //alert(document.getElementById("ctl00_ContentPlaceHolder1_txtPhoneNumber").value);
     if(regexp.test(document.getElementById("ctl00_ctl00_ContentPlaceHolder1_ContentProfile_txtMobileNumber").value))
     {
        return true;
     }
     else
     {

      alert('Phone is invalid');
     return false;
     }
     }

并将此函数调用给自定义验证器

and calling this function to custom validator

<asp:CustomValidator ID="CVtxtPhoneNumber" ClientValidationFunction="check();" ControlToValidate="txtMobileNumber" runat="server" ErrorMessage="Enter a valid Phone No."  ValidationGroup="EditProfile" SetFocusOnError="True" Display="Dynamic"></asp:CustomValidator>

问题是显示警报，但我只希望显示错误消息输入有效的电话号码".不是alert

The problem is that alert is displayed but i want the only the error message is displayed "Enter a valid phone no.". not the alert

答

/; var regexp = 新 RegExp(pattern); // alert(document.getElementById("ctl00_ContentPlaceHolder1_txtPhoneNumber").value); 如果(regexp.test(document.getElementById(" ).返回真； } 其他 { alert(' 电话无效')；返回假； } }

/; var regexp = new RegExp(pattern); //alert(document.getElementById("ctl00_ContentPlaceHolder1_txtPhoneNumber").value); if(regexp.test(document.getElementById("ctl00_ctl00_ContentPlaceHolder1_ContentProfile_txtMobileNumber").value)) { return true; } else { alert('Phone is invalid'); return false; } }

首先，您需要具有两个参数sender和args
为check(sender,args)，并且要显示错误消息时需要设置args.IsValid = false; .验证者自己会注意休息.

您的检查功能将为

First you need to have two arguments sender and args
as check(sender,args) and you need to set args.IsValid = false; when you want to show error message. Rest thing will be take care by validator itself.

your check function would be as

function check(sender,args)
        {
        var pattern=/^[A-Za-z0-9]{10}

/; var regexp = new RegExp(pattern); //alert(document.getElementById("ctl00_ContentPlaceHolder1_txtPhoneNumber").value); if(regexp.test(document.getElementById("ctl00_ctl00_ContentPlaceHolder1_ContentProfile_txtMobileNumber").value)) { args.IsValid = true; } else { args.IsValid = false; } }
