View Full Version : indesign JS command "document.close" renders script useless - need help!

hey guys,

I have a (seemingly) fully working indesign script which opens up documents and indexes the contents.
it puts out the index fine, as long as I do not close the documents.

right now it
- opens
- analyzes
- opens next
- analyzes
- spits out the index of all docs

if I add a close in the loop after the analyze I get an Error 45 / Object is invalid alert on my index list

if (myFile != null) {
try {
// main routine. documents are opened , analyzed, closed, next.
for (x=0;x<myFile.length;x++) {
myOpenFile = myFile[x]
myDocument = app.open(myOpenFile);
mySearchPresets(); //also calls the search function and returns "myFoundList"

app.activeDocument.close(); // if I leave out this line everything works great.

} catch (e) {
alert ("Es ist ein Fehler beim Öffnen von\n" +myFile+ "\naufgetreten!\n\n" + e, "Fehler");

after this it jumps to this function

function myArtNumList(){
mySearchResultList = [];
myFinalList = [];
i = 0;
a = 0;
//converts text into integer
//myArtNum= +myArtNum;
//alert ("ich sortiere");
//alert (myFoundList[0]);
while (i < myFoundList.length) {

myArtNum = myFoundList[i].contents; // this is the part I get the 45 error on ...

// sort and output is omitted here

any thoughts on this? thanks for your help!

No idea what your myFoundtList contains, but if it contains *REFERENCES* to data in the document then of course the error makes sense.

Possibly you need to clone the objects/text/whatever you find before putting it in myFoundList, so that the list references JS objects in memory instead of objects in the document.

thanks! that just might be it! it searches for different types of text and puts the results into "myFoundList". so I would probably end up with the reference to the text instead of the text itself.

Do you have a quick hint how I could clone the contents so that the reference will get lost?

EDIT: I'm on it. I just might have found a way...

Just do

var copy = new String( reference_to_contents );

Or you can even simply do

var copy = "" + reference_to_contents;

If the contents are other than a string, you can find ways to clone objects via google query: "javascript clone object"

Thank you so much! That was the hint I needed!
