Java Script Calculation in PDF Form

Hello there

 

This might be easy for someone: 

I'd like to calculate in a PDF Form. 

 

I have 2 components which are relevant for the calc: 

1. Amount (whole numbers)

2. Checkbox (if this is checked, the amount should be multiply by 16 insted of 14)

 

There should be a condition: 

if the amount is between 2 and 4, it should multiply by 0.85

if the amount is between 5 and 9, it sould multyply by 0.75

if the amount is 10 or greater than 10 it should multyply by 0.50 

 

Any ideas? 

Would be so helpful.

If I understand  right, try use this code as calculation script of "Result" field:

var check = this.getField("Checkbox").valueAsString;
var num = Number(this.getField("Amount").value);
var x = 0;
var y = 0;
if(check == "Off")
x = 14;
else if(check != "Off")
x = 16;
if(num >= 2 && num <=4)
y = (num*x)*0.85;
else if(num >= 5 && num <=9)
y = (num*x)*0.75;
else if(num >= 10)
y = (num*x)*0.50;
else y = num*x;
event.value = y;

 


Hi Nesa

 

Thanks for your reply. 

 

I somehow managed to do it like that:

var amount = this.getField("amount").value; 
var checkbox = this.getField("checkbox");

if (amount === 1) 
{ 
if (checkbox.value != "Off") {
this.getField("total").value = amount*16; 
} else {
this.getField("total").value = amount*14
}
} 

else 
{ 
if (amount >= 2) 
{ 
if (checkbox.value != "Off") {
this.getField("total").value = amount*16*0.85; 
} else {
this.getField("total").value = amount*14*0.85
}
}

else 

// with more steps for higher numbers and >= arguments 
}
}

 

I tested your code and it worked perfectly as well! Thank you 🙂

When you say if checkbox is checked amount is multiply by 16 instead of 14, that means if checkbox is not checked amount is multiply by 14?

So where does then other conditions comes to play?

All of this happening in one field?

    Hi Asim

     

    Thanks for the reply

     

    With the status checkbox off, the calc should be

    Amount (e.g. 5) * 14 = 70

     

    With the checkbox selected, it should switch to

    Amount (e.g. 5) * 16 = 80 

     

    And this sould be multiplied by 0.75 (because 5 is in between 5-9).

     

    I work with 3 Fields:

    1. Amount (Textfield for the numbers)

    2. Checkbox Switch (for the switch from 14 to 16)

    3. Result (Textfield with can't be edited)
