Script to automate the function of buttons

[Samuel22307458169h]

Hello, I have written a script that assigns each button the visibility of 2 levels. The script works fine but when I reopen the PDF the function no longer works.

I have many languages in the pdfs I create and I usually use the set visibility level action in the button properties, but I wanted to automate this. How can I do this?

In the attached code I have only inserted 2 layers

var livBase = "Base";
var livIT = "Italiano";
var livEN = "Inglese";

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

function livelloInglese() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livEN || ocgs[i].name === livBase);
    }
}

function livelloItaliano() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livIT || ocgs[i].name === livBase);
    }
}

Yes is possible, like this:

var cScriptCode = "\nvar livBase = 'Base';\nvar livIT = 'Italiano';\nvar livEN = 'Inglese';\nfunction livelloInglese(){\nvar ocgs = this.getOCGs();\nfor (var i in ocgs) {\nocgs[i].state = (ocgs[i].name === livEN || ocgs[i].name === livBase);\n}\n}\nfunction livelloItaliano(){\nvar ocgs = this.getOCGs();\nfor (var i in ocgs) {\nocgs[i].state = (ocgs[i].name === livIT || ocgs[i].name === livBase);\n}\n}";
this.addScript("scriptPulsanti", cScriptCode);

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

I did various tests and also found suggestions in Adobe's API reference manual.

I created a "Run Javascript" action with this code and it works great

The setAction command shouldn't be a part of your code. You only need to run it once, from the JS Console.

[Samuel22307458169h]

Thanks for reply, what I would like is to have a command that automatically does what I could do with the Set visibility layer action.
That is, for each button I associate the visibility of the layer, each button has its own specific name.

[try67]

Your code does that, but the inclusion of the setAction command is unnecessary and will cause it not to work outside of Acrobat.

[Samuel22307458169h]

var livBase = "Base";
var livIT = "Italiano";
var livEN = "Inglese";

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

function livelloInglese() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livEN || ocgs[i].name === livBase);
    }
}

function livelloItaliano() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livIT || ocgs[i].name === livBase);
    }
}

Are you running it from the Console? You need to select the full code if you do. But that's not how you should use it.

Put this code under a doc-level script:

// Doc-level code
var livBase = "Base";
var livIT = "Italiano";
var livEN = "Inglese";

function livelloInglese() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livEN || ocgs[i].name === livBase);
    }
}

function livelloItaliano() {
    var ocgs = this.getOCGs();
    for (var i in ocgs) {
        ocgs[i].state = (ocgs[i].name === livIT || ocgs[i].name === livBase);
    }
}

And then run this code from the JS Console, making sure to select all of it before executing it:

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

[Samuel22307458169h]

It works! but I have a question, do I have to do this for every document? or is there a way to have it by default in every pdf?

[try67]

You have to add this to every document where you want this to work. You can do it as an Action and run it on multiple files, but you can't do it automatically for any file you open, no.

Thanks for your help

I added an action that executes this code:

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

is it possible to insert the code that goes into the javascript of the document with an action?

[Samuel22307458169h · Accepted solution]

Yes is possible, like this:

var cScriptCode = "\nvar livBase = 'Base';\nvar livIT = 'Italiano';\nvar livEN = 'Inglese';\nfunction livelloInglese(){\nvar ocgs = this.getOCGs();\nfor (var i in ocgs) {\nocgs[i].state = (ocgs[i].name === livEN || ocgs[i].name === livBase);\n}\n}\nfunction livelloItaliano(){\nvar ocgs = this.getOCGs();\nfor (var i in ocgs) {\nocgs[i].state = (ocgs[i].name === livIT || ocgs[i].name === livBase);\n}\n}";
this.addScript("scriptPulsanti", cScriptCode);

var pulsanteEN = this.getField("INGLESE");
pulsanteEN.setAction("MouseUp", "livelloInglese()");

var pulsanteIT = this.getField("ITALIANO");
pulsanteIT.setAction("MouseUp", "livelloItaliano()");

[Samuel22307458169h]

I have an issue, when scroll the doc after press the button for language selection, the layer disappeared.

[try67]

Are you sure it's set up correctly, spanning all the pages in your file?

[Samuel22307458169h]

How do I know if it spans all pages?

[try67]

There's no clear indication. You need to set it up that way when you created it. If you didn't, it will only be on one page.

Ok thanks, I investigated and actually the levels were set as never visible, with preflight I set an action that makes them visible if activated, now everything works, thanks again!
