Interactive PDF form - How to stop script from resetting on reopen?

[Puremutations_com]

I have a script that counts the checked boxes up to a predefined number (lets say 5) and stops users from checking more boxes. But when I close and reopen I can check another 5. Is there a way to prevent this from happening?

//----------------------------Document JavaScript Code ----------------------------

var counter = 0;                 // Checked counter

//--------Count Checked boxes again when document is closed and re-opened ------------

for (var i =0; i<= 100; i++){

          if (getField("chkBox" + i).value == "Yes"){

          counter += 1;

          }

}

//-------------Validation Function ---------------------------------------------------

function validateCheckBox(name,value){

          if (value == "Yes" && counter < this.getField("Quantity_Produits_Finale").value){

                    counter += 1;

          }else if (value == "Off"){

                    counter -= 1;

          }else{

                    getField(name).value = "Off";

                    app.alert("Vous ne pouvez pas sélectionner plus de " + this.getField("Quantity_Produits_Finale").value + " produit(s)");

          }

}

//-----------------End of Document Javascript------------------------

Action on each checkbox

validateCheckBox(event.target.name,event.target.value);

I don't see where you inserted my code. It needs to come instead of

everything that you have at the doc-level. Everything else can stay the

same.

I got it! Thank you very much for your help!!!

Counter needs to start at -1 otherwise only 4 are selected and message pops at the 5th.

[try67]

No, don't do that. Instead, change this line:

if (counter>Number(this.getField("Quantity_Produits_Finale").value)) {

To:

if (counter>=Number(this.getField("Quantity_Produits_Finale").value)) {

[Puremutations_com]

I reset counter value to 0. But I can only select 3 when adding the =

[Puremutations_com]

I found my mistake. Thanks!

[try67]

You can actually remove this part of the code:

if (value == "Yes"){

    counter++;

}   

[Puremutations_com]

Even with >= and code removal counter needs set to -1. It is when user selects the 6th box that error message pops up.

[try67]

Works fine for me...

function validateCheckBox(name,value){
    var counter = 0;
    for (var i=0; i<this.numFields; i++) {
        var f = this.getField(this.getNthFieldName(i));
        if (f==null) continue;
        if (f.type=="checkbox" && /^0 Check Box/.test(f.name) && f.value=="Yes") {
            counter++;
        }
    }
    if (counter>=Number(this.getField("Quantity_Produits_Finale").value)) {
        this.getField(name).value = "Off";
        app.alert("Vous ne pouvez pas sélectionner plus de " + this.getField("Quantity_Produits_Finale").value + " produit(s)");
    }
}

When clicking the fifth box, the error message appears.

[Puremutations_com]

That's it! I need to be able to check the fifth box. Hence the -1.

[try67]

OK, then your description was not clear... Anyway, if it works leave it as is, although starting from -1 is not the best practice.

[Puremutations_com]

It works perfectly!

[Bernd Alheit]

OK.

You should look at the console for error messages.

[Puremutations_com]

The issue I am having is the checked boxes counter reset to 0 every time I reopen this saved file and check new boxes. When I want it to retain the value of this.getField("Quantity_Produits_Finale").value (lets say 5) and stop people from checking new boxes.

So in other words on first go it stops at 5. OK
I save and reopen file
It allows me to check another 5 boxes when it should simply stop the user from checking more than 5 boxes NOT OK

I simply don't know how to implement that correctly?

[Bernd Alheit]

Your code at file open is incorrect. Look at the error message.

[Puremutations_com]

Ok! How do I fix this?

[Bernd Alheit]

Change the code.
