How to encode data from few text fields to QR Barcode field. ?

I moved your question to the Acrobat forum, first of all.

Are you using an actual Barcode field, or a text field with a barcode font?

If the latter, it depends on that font's encoding options.

If the former, I would recommend you use the built-in option to calculate the field's value, and then examine the code it generates and adapt it to your specific needs. Just remember this won't work when used in Reader!

I want to encode the form field values embedded to the barcode field via Adobr Javascript. I am developing in Adobe Acrobat Pro.

I am able to pass data to the barcode field in clear text with below code. But I need to encode the same. 

Please provide a solution for it asap

My code is as below

var F02 = "F02~" + this.getField("txtAmount").value;

var F03 = "F03~" + this.getField("txtChargeCode").value;

vardSep='||';

var Result = F02
+ dSep + F03

this.getField("Barcode").value = Result.toUpperCase() + '\r\n';
