PageItem showing as valid when checked with JS but it actually does not exists in the document.

hello all,

var thedoc = app.documents.item(0);

var thepitem = thedoc.pageitems.itembyid(1784);

$.writeln(thepitem.isvalid);

hi bhumika,

iterate through allpageitems array of document , ids.

a pageitem id 1784 not there.

 

it misconception think available ids pageitem class denote object on page.

what return pageitem resolved? :

 

app.documents[0].pageitems.itembyid(1).getelements()[0]; // returns: [object document] 

 

what return in case?

 

app.documents[0].pageitems.itembyid(1784).getelements()[0]; // returns: [object pageitem] 

 

i ran following script on document german estk:

 

var doc = app.documents[0];  for(var n=1;n<2000;n++) {     try{     $.writeln(n+"\t"+doc.pageitems.itembyid(n).getelements()[0]);     }catch(e){n+"\t"+e.message}; } 

 

here results.

note, ids missing without being caught error handler:

"objekt ist ungültig" => "object not valid" ( message error handler )

 

so pageitem id 1784 existing, not item think is.

and yes, reading out properties crash indesign.

 

uwe

 

btw.: thread should moved indesign scripting
