get status of cross references

[ep_nna]

Hi all

Is there a way to get the status of a cross reference in JavaScript, basically like LinkStatus.LINK_MISSING etc. but for cross references? I would like to loop through a book and report cross references with errors (missing document, missing source etc.) to the user.

Not really. Cross-references are underlyingly huperlinks whose source is a CrossRefereceSource. So you'd have to check those hyperlinks (they're not visible in the Hyperlinks panel).

If the cross-ref's source is deleted, the hyperlink is deleted as well.

If the cross-ref's destination is deleted, then the hyperlink's destination is null.

That's about all you can determine as far as I know.

Hi Peter

That's disappointing. Anyway, what I tried to do was finding hyperlinks with source CrossReferenceSource and destination null, like so:

var _currDoc = app.activeDocument;
var _errorHyperlinksDoc = [];
for (var i = 0; i < _currDoc.hyperlinks.length; i++) {
    var _hyperlink = _currDoc.hyperlinks[i];
      if (_hyperlink.source == "[object CrossReferenceSource]" && _hyperlink.destination == null) {
        _currDoc.hyperlinks[i].showSource();
        _errorHyperlinksDoc.push(app.selection[0].parentTextFrames[0].parentPage.name)
    }  
}
alert(_errorHyperlinksDoc);

However, even though one of my two cross references is kind of broken (it's not red with a question mark but a red flag with a question mark, so the destination has been deleted and should therefore be null (?)), the alert at the end returns empty. So, is there a way to achieve what I'm trying to do at all?

Your script works fine over here, not sure why it doesn't work at your end. Maybe you could post the file.

Your script can be made more efficient as follows. Functionally it's the same as your script, it's just more efficient:

var _currDoc = app.activeDocument;
var _errorHyperlinksDoc = [];
var hlinks = _currDoc.hyperlinks.everyItem().getElements();
for (var i = 0; i < hlinks.length; i++) {
  var _hyperlink = hlinks[i];
  if (_hyperlink.source instanceof CrossReferenceSource 
      && _hyperlink.destination == null) {
    _errorHyperlinksDoc.push (
      _hyperlink.source.sourceText.parentTextFrames[0].parentPage.name
    );
  }
}
alert(_errorHyperlinksDoc);
