I have never written a script for indesign before so I am not really familiar with how it works

Eessentailly, I have a text box that a user would be writting a state in. I then want the script to take that as input, and then make a hidden image of that state visible.

Also, is it possible to have th script always running, or would the end user have to run it?

Thank you!

Hi,

It is possible using eventListeners. Look at example below and be awared that this is an example ONLY:

To switch this ON run:

#targetengine "session"
var myDoc = app.activeDocument;
myDoc.addEventListener("afterSelectionChanged", myDisplay);
function myDisplay(myEvent){
     if(app.documents.length == 0) return;
     var curDoc = app.activeDocument;
     if(curDoc.selection.length == 0) return;
     var 
          myInput = curDoc.textFrames.item("input"), 
          myOutput = curDoc.pageItems.item("output");
     if (!myInput.isValid || !myOutput.isValid) return;
     if (myInput.contents == "ON") myOutput.visible = true; 
     else myOutput.visible = false;  
}

to switch this OFF run (or quit InDesign):

app.activeDocument.eventListeners.everyItem().remove()

Assumings:

  • input textFrame is named "input" (I mean in "Layer's Panel")
  • output pageItem is named "output"
  • type "ON" to make "output" visible
