单击另一个旨在显示/隐藏图层的按钮时，在Adobe PDF中隐藏/显示按钮的代码是什么？

Question

I have a button that I edited the action to "run a JavaScript" under "Mouse Down."

This is the code I put into the JavaScript (Button is titled "Site External Doors"):

var docOCGs = this.getOCGs(); 
for (var x=0; x < docOCGs.length; x++) 
{
          if(docOCGs[x].name == "Site External Doors" ||
     docOCGs[x].name == "Site External Doors")
          {
                    docOCGs[x].state = !docOCGs[x].state; 
 }
}
// Button Style and Label Change 
if(event.target.borderStyle == border.b)
{
          // Perform Push Down Actions
          event.target.borderStyle = border.i;

          event.target.buttonSetCaption("Site External Doors Off");
} else {
          // Perform Pop Up Actions

          event.target.borderStyle = border.b;

          event.target.buttonSetCaption("Site External Doors On");
}

This code shows a layer when clicked and hides the layer when clicked again. I am wondering what code I need to add to get another button (titled "Door 52") to appear when the button "Site External Doors" is clicked and hide when it is clicked again.

Acroform buttons, like other fields, have a "display" property you can set. You should be able to set the "Door 52" button to be hidden on creation, then make it visible with code such as:

// Show the button
var door52 = getField("Door 52");
door52.display = display.visible;

// Hide the button again
door52.display = display.hidden;
