如何利用js正则表达式判断ip地址的合法性

Posted 2023-04-26

在DW软件上，选中文本框，

在Spry里选择Sqry验证文本域，下面选择类型->IP地址

参考技术A function ValidateIPaddress( ip )   
    if( /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/.test( ip ) )   
        return true;
      
    alert("You have entered an invalid IP address!");
    return false;

下面的正则可以验证IPv6地址：

/^(([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])$|^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\\-]*[a-zA-Z0-9])\\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\\-]*[A-Za-z0-9])$|^\\s*((([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|((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3)|:))|(([0-9A-Fa-f]1,4:)5(((:[0-9A-Fa-f]1,4)1,2)|:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3)|:))|(([0-9A-Fa-f]1,4:)4(((:[0-9A-Fa-f]1,4)1,3)|((:[0-9A-Fa-f]1,4)?:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3))|:))|(([0-9A-Fa-f]1,4:)3(((:[0-9A-Fa-f]1,4)1,4)|((:[0-9A-Fa-f]1,4)0,2:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3))|:))|(([0-9A-Fa-f]1,4:)2(((:[0-9A-Fa-f]1,4)1,5)|((:[0-9A-Fa-f]1,4)0,3:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3))|:))|(([0-9A-Fa-f]1,4:)1(((:[0-9A-Fa-f]1,4)1,6)|((:[0-9A-Fa-f]1,4)0,4:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3))|:))|(:(((:[0-9A-Fa-f]1,4)1,7)|((:[0-9A-Fa-f]1,4)0,5:((25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d)(\\.(25[0-5]|2[0-4]\\d|1\\d\\d|[1-9]?\\d))3))|:)))(%.+)?\\s*$/

Js 正则表达式验证IP地址

1.验证方法

function isValidIP(ip) {
    var reg = /^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/
    return reg.test(ip);
} 

2.判断

isValidIP(NewIP) == false
