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?
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)
