Convert digits into words with JavaScript in PDF Form

Question

When I use the code as mentioned by Salman in Convert digits into words with JavaScript in my PDF form in Foxit Reader - custom calculation script, it does not work and when I see the console it says :

======== Field : calculate ========
[ Line: 00015 { ReferenceError } ] : document is not defined

What I need to modify in this to get it working in PDF form?

Answer 1

You obviously need to change the code

document.getElementById('number').onkeyup = function () {
    document.getElementById('words').innerHTML = inWords(document.getElementById('number').value);
};

to the equivalent in foxit

Something like

this.getField ("words").value = inWords(this.getField("number").value)
