Javascript for subtraction

[Nikolaos.]

In Excel I would do it like this:

= (total vacation - vacation already taken) - requested vacation

How can I write this into a text field in javascript?

Hi,

It is quite straight forward.

• Open the document you are working on
• At the top of your screen, click on the Tools tab
• Type 'form' in the search field
• in the results, click on 'Create form'
• 
• your opened document should be visible, or get it from your scanner or start a new one
• Clcik on start to detect fields, 
• Create the fields you need 

• Make sure to name the fields in a logical/meaningful way
• In the Properties of the last one (to display result of the calculation)

• enter your calculation
• Click on Close
• At the top right f the screen toggle between Preview and Close to test your 'function'

In SFN you need to escape space character with backslash.

As far as I've been able to try it, it doesn't work.

Is it possible for you to send me the exact code that I need to insert to accomplish a subtraction?

[Nikolaos.]

Thank you for this step-by-step description, very helpful.

But after several attempts I can say that it doesn't work.

It doesn't do subtraction.

I also tried it with GPT, here is the code. Thanks everyone for your help.

var fieldValue1 = parseFloat(this.getField("Textfeld1").value);

var fieldValue2 = parseFloat(this.getField("Textfeld2").value);

var fieldValue3 = parseFloat(this.getField("Textfeld3").value);

if (!isNaN(fieldValue1) && !isNaN(fieldValue2) && !isNaN(fieldValue3)) {

    var result = fieldValue1 - fieldValue2 - fieldValue3;

    this.getField("Ergebnisfeld").value = result;

} else {

    this.getField("Ergebnisfeld").value = "";

}

If this is a calculation script replace this.getField("Ergebnisfeld").value = ... with event.value = ... .

I am very surprised. As you can see from the screenshots, the calculation works. Can you explain (with screenshots) what does not work for you?

I'm having the same issue. My fields are SUBTOTALA and SUBTOTALB

In the Simplified Field Notation box, I type:

SUBTOTALA-SUBTOTALB

Acrobat acts like it's going to calculate, the formula "blips" in the box, then the radio box goes back to no calculation. The same thing happens when I type

SUBTOTALA - SUBTOTALB

[try67]

Radio-button fields do not have a Calculate tab... Where exactly are you applying this code?

[sonyaa5264881]

Well, I did the EXACT SAME CODE in the EXACT SAME PLACE today and it worked perfectly. I saved quickly, thanked my lucky stars and went on my merry way!

What field names do you use?
