Adobe Acrobat JavaScript

Question

I'm a graphic designer working on an order confirmation form with Adobe Acrobat. I know nothing of Javascript but I managed to write a formula to calculate the price of items on the pdf.

Now I'd like to fix one last thing, if I don't want the number to show up when it is less than 0 what should I do?

the script right now is pretty simple: event.value = ( this.getField("fill_1").value * this.getField("Prezzo € x kg Prezzo € x foglioRow1").value )

Fill_1 and Prezzo € x kg Prezzo € x foglioRow1 are the names of the cells.

Is there any online tool to help me figure this out? do you have any advice?

Answer 1

It's a matter of a simple condition. Does this work?

var x = ( this.getField("fill_1").value * this.getField("Prezzo € x kg Prezzo € x foglioRow1").value );
event.value = x < 0 ? "" : x;

If the line above didn't work then I'm stumped. I would the followings:

• what event is that?
• does it have more relevant code?
• did you mean x <= 0 ?
• what happens if event.value = 12 ?
• what happens if event.value = 'hello' ?
• what happens if event.value = this.getField("Prezzo € x kg Prezzo € x foglioRow1").value ?
