Is it possible to select text boxes with javaScript in acrobat

I would like to be able to use the JavaScript function of one of my form inputs to be able to show or hide a text box. After a lot of research I can only find how to select and hide other form input methods.

here is what I have:

var supplyBudget = this.getField("Supply Budget").value;
if (supplyBudget == ""){
/*text box selector*/.style.display = 3;
}
else if (supplyBudget =="0"){
/*text box selector*/.style.display = 3;
}
else{
/*text box selector*/.style.display = 1;
}

This runs when the user leaves the input field.

Solution

  • If you want to hide text that is part of the page content, you can't do that with PDF unless that particular text item is assigned to an Optional Content Group (OCG)... basically a layer that you can show or hide. There is no concept of "elements" for PDF page context like there is in HTML. Instead, there's a list of painting instructions for the page but JavaScript does not have access to it.
