Change filename into link

Question

I want to change the filename of a link into Indesign. For example: the existing filename is table_EX.jpg and now I want it to change into table_CZ.jpg
I wrote a script, but it seems that it only change ONE link. Who can help me?
#target indesign
// Relink file fileName.js
if (app.documents.length == 0) {
     err("No open document. Please open a document and try again.", true);
var myDoc = app.activeDocument;
var myLinks = myDoc.links;
var myCounter = 0;
if (myLinks.length == 0) {
     err("This document doesn't contain any links.", true);
for (i = myLinks.length-1; i >= 0 ; i--) {
     var myLink = myLinks[i];
     var myOldfileName = myLink.name;
     var myNewfileName = myOldfileName.replace("_EX", "_CZ");
     var myNewFile = new File(myNewfileName);
     if (myNewFile.exists) {
          myLink.relink(myNewFile);
          myCounter++;
document.save()
document.close()

Answer 1

Change
var myLinks = myDoc.links;
to
var myLinks = myDoc.links.everyItem().getElements();
This should work, because myLinks will not change during the updates.
Hope that helps.
