java calculations

[paula99520745]

Hi All

Anyone able to help, I'd like to use or reference a fixed value so I can use it in a java calculation

I need to do this all in java, so my script needs to hold the value and I want to use it in some simple maths cals

This should be so easy but the material examples I am finding on the Net on Adobe pdf java is not helping me.

I been through Thoms video on Youtube and Iam still none the wizer

Acrobat uses JavaScript, not Java.

For a fixed value you can use a variable like:

var price = 1.23;

[paula99520745]

Yes I have a declared variable

var AF = 5;

My problem is when I add a calculation, like

+ "Admin $"  [Af] + "\n";

I cant use it to produce an answer

What I have is a sub total

I'd then like to show the AF variable

Then I wish to add the sub total and AF together as a Grand Total

your thoughts?

[try67]

To access the value of a field you need to use this syntax:

this.getField("Af").value

Notice the JS is case-sensitive, so if the field is called "AF" you have to enter it like that, not as "Af".

Thanks for the help.

Perhaps I should have said the result is being calculated in a popup text box

because this doesn't work

+ "Admin $" this.getField("AF").value;

This is the full script:

---

var msgText = "There are " + this.numPages + " pages in this document\n"; 

// counters 
var numA4 = 0; 
var numA3 = 0; 
var numA2 = 0;
var numA1 = 0; 
var numA0 = 0;
var p = .20;
var AF = 5.00;

// Values
var A4 = numA4*p;
var A3 = numA3*p;
var A2 = numA2*p;
var A1 = numA1*p;
var A0 = numA0*p;
var Sum = 0;

// helper function to compare a number with some wiggle room 
function inRange(wid,hei,targetWid,targetHei) { 
    var wiggle = 288; // amount of error to allow 
    return (wid>=(targetWid-wiggle) && wid<=(targetWid+wiggle)) &&  (hei>=(targetHei-wiggle) &&    hei<=(targetHei+wiggle)) || (hei>=(targetWid-wiggle) && hei<=(targetWid+wiggle)) &&  (wid>=   (targetHei-wiggle) && wid<=(targetHei+wiggle))  } 
 
for (pagenum=0;pagenum<this.numPages;pagenum++) { 
    var pbox = this.getPageBox("Crop",pagenum); 
    var width = (pbox[2] - pbox[0]); 
    var height = (pbox[1] - pbox[3]); 
   var recognized = false; 
        if (inRange(width,height,595,842)) { numA4++; recognized = true; }   
        if (inRange(width,height,842,1191)) { numA3++; recognized = true; } 
        if (inRange(width,height,1191,1684)) { numA2++; recognized = true; }
        if (inRange(width,height,1684,2384)) { numA1++; recognized = true; }
        if (inRange(width,height,3502,4566)) { numA0++; recognized = true; }   
 
    if (!recognized) msgText += ("Page " + (pagenum+1) + " has a width of " + (width/72).toFixed(2) + " and a height of " + (height/72).toFixed(2) + "inches\n");  } 
msgText +=
  numA4 + " A4 pages $" + (numA4*p).toFixed(2) + "\n"
+ numA3 + " A3 pages $" + (numA3*p*2).toFixed(2) + "\n"
+ numA2 + " A2 pages $" + (numA2*p*4).toFixed(2) + "\n"
+ numA1 + " A1 pages $" + (numA1*p*8).toFixed(2) + "\n"
+ numA0 + " A0 pages $" + (numA0*p*16).toFixed(2) + "\n"
+ (this.numPages++ - (numA4+numA3+numA2+numA1+numA0)) + " other pages" + "\n"
+ "SubT $" + (numA4*p+numA3*p*2+numA2*p*4+numA1*p*8+numA0*p*16).toFixed(2) + "\n"
+ "Admin $" this.getField("AF").value;

app.alert(msgText);

You forgot to add a plus sign before that statement...

[paula99520745]

Ok the script now runs

so it looks like...

+ this.getField +("AF").value;

This still wont bring up the answer set against the variable

var AF = 5.00

It should be reporting on the last line

Admin $5.00

If you copy-n-paste my full code and run it against any multiple paged pdf you will see how it works.

What I am wanted to achieve is;

an iteration of the pages, valued

sum of the 'other pages' - this is pages that are not within the paper spec's

a Sub Total

A new line for Admin of $5.00

And a new Grand total

[try67]

Works fine for me...

[paula99520745]

I don't get the output.

I get the green tick to indicate the script ran, but no output

Command Name: Execute JavaScript

Command Start Time: 2018-02-13 12:40:40

Command Status: Succeeded

Command Finish Time: 2018-02-13 12:40:40

Any ideas whats up?

[try67]

Where are these commands and this output are coming from? I'm not familiar with anything like that in Acrobat.

[paula99520745]

If your referring to

Command Name: Execute JavaScript

Command Start Time: 2018-02-13 12:40:40

Command Status: Succeeded

Command Finish Time: 2018-02-13 12:40:40

They come from here

[try67]

Ah OK, you're running it from an Action. I suggest you run it from the JS Console window first, and see what the results are.

[paula99520745]

Thanks for the help. still did not run from console

[paula99520745]

Correction. now that I remember how to do this.

I did get it to run in Console

and it shows an error.

TypeError: this.getField("AF") is null

52:Console:Exec

There are 4 pages in this document

4 A4 pages $0.80

0 A3 pages $0.00

0 A2 pages $0.00

0 A1 pages $0.00

0 A0 pages $0.00

0 other pages

subT $0.80

[Thom Parker]

There's you answer right there, field "AF" does not exist on the document.

[paula99520745]

You lost me Thom

Try67 on 12/02/2018 managed to demonstrate he did produce the value from the Variable held??

Which is what I am trying to do as well, I am at a loss as to why he ran the identical script and did get the value but when I run it I get nothing

I want the code told hold a variable that I can change to be displayed on the popup box

The value is in the script code var AF = 5.00;

I don't know how this relates to your comment that AF is no in the document?

Perhaps the answer lies in how the AF value is being held, can you not simply display a variable without using it in a calculation

[try67]

In your code you're trying to insert the value of a field called "AF" into the message string. Since there's no such field in the file, the error you see is thrown.

[paula99520745]

The bit of code I think we are talking about is

+ "Admin $" + this.getField("AF").value;

I have in the script

var AF = 5.00;

What I want to get is the line reporting

Admin $5.00

[try67]

Use Bernd's code from his last reply.

[Bernd Alheit]

Create text field with the name "AF" and put the value 5 in it.

[paula99520745]

I am not using a form, this is purely a script

or can I create a 'test' field in the script to hold the value? I thought that's what the variable did?

[Bernd Alheit]

You can use a variable AF

var AF = 5.0;

and access the variable

+ "Admin $" + AF;

[paula99520745]

Replaced

+ "Admin $" this.getField("AF").value;

with

+ "Admin $" + AF;

This has improved things as the script now runs and generates the popup again.

But still didn't produce the line Iam after

Admin $5

[try67]

Once more, if you don't post your full code we can't help.

[paula99520745]

Sorry I didn't see that request.

Its actually in the tread above, but here it is as it sits now
