这里他使用了jqueryvalidator.js并用例子进行了解释。

 $.validator.addMethod('IP4Checker', function(value) {
            var ip = "^(?:(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.){3}" +
                "(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)$";
                return value.match(ip);
            }, 'Invalid IP address');

            $('#form1').validate({
                rules: {
                    ip: {
                        required: true,
                        IP4Checker: true
                    }
                }
            });

简短版本：

^(?!0)(?!.*\.$)((1?\d?\d|25[0-5]|2[0-4]\d)(\.|$)){4}$

Answer 3

您可以使用正则表达式来测试IP是否有效：

"127.0.0.1".match(/^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/);

Answer 4

嗨，这是IP地址的最佳解决方案和掩码

$.validator.addMethod('IP4Checker', function(value) {
        var ip = /^(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))\.(\d|[1-9]\d|1\d\d|2([0-4]\d|5[0-5]))$/; 
        return value.match(ip);
        }, 'Invalid IP address');

    var $validator = $("#addCardForm").validate({
          rules: {
              txtIP: {
              required: true,
              IP4Checker: true
              }

          }
        });

Answer 5

这适用于IP地址

$.validator.addMethod('IP4Checker', function(value) {

    var ip="^([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
    "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
    "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
    "([01]?\\d\\d?|2[0-4]\\d|25[0-5])$";
        return value.match(ip);
    }, 'Invalid IP address');

    $('#remoteForm').validate({
        rules: {
            ipAddr: {
                required: true,
                IP4Checker: true
            }
        }
    });

Answer 6

我使用jQuery Validation Plugin：

$.validator.addMethod('IP4Checker', function(value) {
        var ip = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";
            return value.match(ip);
}, 'Invalid IP address');

$('#form').validate({
    rules:{
        ip:{
            required: true,
            IP4Checker: true
        }
    }
});

希望有所帮助。

/* 
    validIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";
    validHostnameRegex = "^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\-]*[A-Za-z0-9])$";

$.validator.addMethod('ipChecking', function(value) {
    //var ip = "^(?:(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\.){3}" +"(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)$";
    validIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";
    ipCheckFlag = true;
    ipLists = value.split(',');
    for(ip=0; ip<ipLists.length; ip++){
        if(!ipLists[ip].trim().match(validIpAddressRegex)){
            ipCheckFlag = false;
        }
    }
    return ipCheckFlag;     
});

除了@RAVI MONE对具有子网掩码的IP地址的回答：

$.validator.addMethod('IP4Checker', function(value) {
    var ip="^$|([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
      "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
      "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\." +
      "([01]?\\d\\d?|2[0-4]\\d|25[0-5])((/([01]?\\d\\d?|2[0-4]\\d|25[0-5]))?)$";
    return value.match(ip);
}, 'Invalid IP address.');

Answer 9

如果IP地址格式正确，则此函数返回<div class="item"> <div class="two-half"> <div class="wrap">1</div> <div class="wrap">2</div> </div> <div class="two-half"> <div class="wrap">3</div> <div class="wrap">4</div> </div> </div> <div class="item"> <div class="two-half"> <div class="wrap">5</div> <div class="wrap">6</div> </div> <div class="two-half"> <div class="wrap">7</div> <div class="wrap">8</div> </div> </div>，否则返回true：

false
