how to hide or show a field after the form is digitally signed | Acrobat pdf forms

I have a form that needs to be digitally signed. After the form is signed, all form fields are made readonly from the properties. But my buttons are not hidden. What can I do to hide the buttons??

PS - I am using acrobat 15

Solution

  • There seems to be no in-built function or property to achieve the desired result. But I got a simple javascript that I could use to make all fields readonly and hide all buttons both at the same time.

    for ( var i = 0; i < this.numFields; i++) {
    var fname = this.getNthFieldName(i);
    if(fname.type == "button")
    {
        this.getField(fname).display = display.hidden;
    }
    else if ( fname != "Signature_2" ) 
           this.getField(fname).readonly = true ; 
}
