Hi All,

 

Please help me how to validate UUID format in Server side script
below script always returning "Not Valid" .

var uuidValue= gs.generateGUID();
uuidValue=uuidValue.replace(/^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$/ "$1-$2-$3-$4-$5");

var uuidRegex = /^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$/;  
    if (uuidRegex.test(uuidValue)) {
       gs.info('Valid');
    } else {
       gs.info('Not Valid');
    }

@Supriya25 

try this

var sysId = '8bafe2e4db072150966c676ed396194c'; // Replace with your sys_id

function convertSysIdToUUID(sysId) {
    if (sysId.length !== 32) {
        gs.info('Invalid sys_id length');
        return null;
    }
    return sysId.replace(/^(.{8})(.{4})(.{4})(.{4})(.{12})$/, '$1-$2-$3-$4-$5');
}

var uuidValue = convertSysIdToUUID(sysId);
gs.info('UUID: ' + uuidValue);

Output:

Hi @terrillc 


is it Not  UUID format ?  please let me know if something wrong happing here.

var sysId = gs.generateGUID();

function convertSysIdToUUID(sysId) {
    if (sysId.length !== 32) {
        gs.info('Invalid sys_id length');
        return null;
    }
    return sysId.replace(/^(.{8})(.{4})(.{4})(.{4})(.{12})$/, '$1-$2-$3-$4-$5');
}

var uuidValue = convertSysIdToUUID(sysId);
gs.info('UUID: ' + uuidValue);

gs.info('UUID: ' + isUUID(uuidValue));
function isUUID ( uuid ) {
    var s = "" + uuid;

    s = s.match('^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$');
    if (s === null) {
      return false;
    }
    return true;
}
*** Script: UUID: 1ba32558-8301-2210-769a-c020feaad329
*** Script: UUID: true

Could you please check above  script once .
