Abort Script If No Document Open

[IanBarber]

I am trying to stop the script from running if No Documents are open.

I have a variable at the beginning of the script which reads...  var docRef = app.activeDocument but it's throwing an error in ESTK if no document is open so I am trying to figure out a way to prevent the script from running if no document is open when the script is started.

I tried the following thinking that if the document length was greater then 0 then it would set the variable otherwise it would exit but this is wrong somewhere.

if(app.documents.length > 0){
var docRef = app.activeDocument
}else{
  return;
  }

try{

var docRef = app.activeDocument;

}

catch(e){

    var noDocs = false;

    }

if (noDocs== false){

    alert ("You do not have a document open.")

}

else {

// run script

}

Hi ian-barber​,

'return' only works in a function.

Your own code should be:

areThereDocuments ();
function areThereDocuments () {
if (app.documents.length > 0) {
    var docRef = app.activeDocument;
    // your code
    // alert (docRef.name);
    } else {
    alert ("no open document");
    return;
    }
}

Have fun
