I have been converting all my PDF document into HTML which is working well but I have one issue and that is the custom validation function I had put inside my PDF in adobe JavaScript I cannot run these in regular JS. Is there converter or libraries that can run this adobe JSX to regular JS or will I have to rewrite my scripts. I have over 300 PDF so if there were a way to do this it would save me a lot of time. Thanks

Sample Code (Adobe Acrobat JS):

function validateDocument() {
    if(this.getField("FIELD1").valueAsString.length == 0)
    {
        app.alert("The field TEST is mandatory");
        return false;
    }
}
