java ipv6校验_JS及java验证 IPV6,IPV4地址的 正则表达式 | 学步园
JS 驗證:
ipv4地址驗證：
function queryDev(ip){
var exp=/^(\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])$/;
var flag = ip.match(exp);
if(flag != undefined && flag!=""){
return true;
} else {
return false;
}
}
驗證IPV6地址：
function queryDev(ipvalue){
var isIpv6 = false;
if(ipvalue.match(/:/g).length<=7&&/::/.test(ipvalue)?/^([\da-f]{1,4}(:|::)){1,6}[\da-f]{1,4}$/i.test(ipvalue):/^([\da-f]{1,4}:){7}[\da-f]{1,4}$/i.test(ipvalue)){
isIpv6 = true;
}
if(isIpv6){
return true;
} else {
return false;
}
}
