How to partially mask the field value

[Vasu ch]

Hi,

I've a field "PAN Card Number" in user table. Whenever the user fills this field, I want to mask the value like BCXXXXXX1D. How can I do this? And how can I retrieve its value when needed?

Thank you.

Hello @Vasu ch 

Write Before BR on the same table and use condition pannumber isnot empty

And use below script-

(function executeRule(current, previous /*, g*/) {
   
    var panField = 'pan_number'; // Change this to match your field name
    var visibleChars = 2; // Number of characters to leave visible (e.g., the first two and the last character)
    var pan = current.panField;
    if (pan && pan.length >= (visibleChars + 2)) {
        // Create a masked PAN
        var prefix = pan.substring(0, visibleChars); // First two characters
        var maskedChars = 'X'.repeat(pan.length - (visibleChars + 2)); // Masked characters
        var suffix = pan.slice(-1); // Last character
        var maskedPAN = prefix + maskedChars + suffix;
        current.panField = maskedPAN;
    }
})(current, previous);

 Please accept my solution and mark as helpful.

But how can we fetch the actual PAN value when required?

Hi @Vasu ch ,
Try below script in before BR when pan not empty

(function executeRule(current, previous /*null when async*/) {
 var panCard = current.u_pan_number;
    if (panCard) {
        var maskedPan = panCard.substring(0, 2) + "XXXXXX" + panCard.substring(8, 9);
        current.u_pan_number = maskedPan;
    }

})(current, previous);

Please mark it as helpful and solution proposed if it serves your purpose.

Thanks,
