Show/hide layer conditional to checkbox and Text Field

Beware that an OCG state is not saved with the document and revert to default each time the document is closed.

I now wish to use that checkbox to make another thing: if the checkbox PA40 and the Text Field named PIED is 18 or higer, it will show the layer named PA4, and if the Text Field named PIED is lower then 18, it will show the layer PA4L.

Place this script in the checkbox:

if (event.target.value != "Off") && (this.getField("PIED").value >= 18) {

    var ocgArray1 = this.getOCGs();

    for (var i=0; i < ocgArray1.length; i++) {

        if (ocgArray1.name == "PA4") {ocgArray1.state = true;}

        if (ocgArray1.name == "PA4L") {ocgArray1.state = false;}

    }

}

else if (event.target.value != "Off") && (this.getField("PIED").value < 18) {

    var ocgArray1 = this.getOCGs();

    for (var i=0; i < ocgArray1.length; i++) {

        if (ocgArray1.name == "PA4") {ocgArray1.state = false;}

        if (ocgArray1.name == "PA4L") {ocgArray1.state = true;}

    }

}

else {

    var ocgArray1 = this.getOCGs();

    for (var i=0; i < ocgArray1.length; i++) {

        if (ocgArray1.name == "PA4") {ocgArray1.state = false;

      if (ocgArray1.name == "PA4L") {ocgArray1.state = false;

     }

}

Thanks, I changed it to this below and it still doesn't work.

var layerName = "PA40";

var layers = this.getOCGs(0).concat(this.getOCGs(1));

if (layers!=null && layers.length!=0) {

for (var i in layers) {

if (layers.name==layerName) {

layers.state = !layers.state;

break;

}

}

}

Been able to make it work by writing the code two times, one with ) and one with 1.

For my questions I was wondering if it would be easier to make a textfield appear instead of a layer, since I only have one item on it.

Thanks a lot

First of all, what's this line supposed to be?

var layers = this.getOCGs(0&&1);

If you're trying to get the OCGs from pages 0 and 1 like that, that's not how it's done.

Change it to:

var layers = this.getOCGs(0).concat(this.getOCGs(1));
