jQuery IP地址validation失败

下面是代码片段，我编写了代码以掩盖IP地址并使用jQuery对其进行validation。 但是，我收到有效IP地址的错误消息（如222.222.222.222）。 有人可以帮忙吗？

//Validate the form $('#form').validate({ rules: { ip: { required: true, IP4Checker: true }, subnet: { required: true, IP4Checker: true }, gateway: { required: true, IP4Checker: true }, dns1: { required: true, IP4Checker: true }, dns2: { required: true, IP4Checker: true } }, messages: { ip: "Please enter a valid IP Address", subnet: "Please enter a valid Subnet Mask Address", gateway: "Please enter a valid Gateway Address", dns1: "Please enter a valid DNS1 Address", dns2: "Please enter a valid DNS2 Address" } }); //Validate the IP addresses $(function() { $.validator.addMethod('IP4Checker', function(value) { var ip = "^(?:(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)\\.){3}" + "(?:25[0-5]2[0-4][0-9][01]?[0-9][0-9]?)$"; return value.match(ip); }); }); //Set mask for IP address fields $(".ip").mask("999 . 999 . 999 . 999"); //Store numbers in hidden field $(".ip").blur(function () { //Create char array from phone number field var charArray = $(this).val().split(""); var num = ""; //taking the input $.each(charArray, function(index, value) { num = num + value; }); }); 

Answer 1

你的正则表达式错过了它 人物即。

 \b(?:(?: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]?) 

另请注意，您可以将此缩短为

 \b(?:\d{1,3}\.){3}\d{1,3}\b 

如果您不需要检查它是0-255之间的有效IP地址

任何\需要自己逃脱，所以它将是\

UPDATE

OP显示小提琴并且没有读过上面的线也掩盖了两侧的空格。 所以正则表达式永远不会有效，因为掩码添加了空格。

固定小提琴

只需用你的function替换

 //IP V4 jQuery.validator.addMethod("IP4Checker", function(value, element, param) { return this.optional(element) || /^(25[0-5]|2[0-4]\d|[01]?\d\d?)\.(25[0-5]|2[0-4]\d|[01]?\d\d?)\.(25[0-5]|2[0-4]\d|[01]?\d\d?)\.(25[0-5]|2[0-4]\d|[01]?\d\d?)$/i.test(value); //IP V6 jQuery.validator.addMethod("IP6Checker", function(value, element, param) { return this.optional(element) || /^((([0-9A-Fa-f]{1,4}:){7}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){6}:[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){5}:([0-9A-Fa-f]{1,4}:)?[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){4}:([0-9A-Fa-f]{1,4}:){0,2}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){3}:([0-9A-Fa-f]{1,4}:){0,3}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){2}:([0-9A-Fa-f]{1,4}:){0,4}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){6}((\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b)\.){3}(\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b))|(([0-9A-Fa-f]{1,4}:){0,5}:((\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b)\.){3}(\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b))|(::([0-9A-Fa-f]{1,4}:){0,5}((\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b)\.){3}(\b((25[0-5])|(1\d{2})|(2[0-4]\d)|(\d{1,2}))\b))|([0-9A-Fa-f]{1,4}::([0-9A-Fa-f]{1,4}:){0,5}[0-9A-Fa-f]{1,4})|(::([0-9A-Fa-f]{1,4}:){0,6}[0-9A-Fa-f]{1,4})|(([0-9A-Fa-f]{1,4}:){1,7}:))$/i.test(value); });
